The Air Force has begun construction of a new underground nuclear weapons storage and handling facility at F.E. Warren Air Force Base in Cheyenne, Wyoming.

The new Weapons Storage and Maintenance Facility (WSMF; sometimes called Weapons Generation Facility), which will replace the current Weapons Storage Area (WSA), will be a 90,000-square-foot reinforced concrete and earth-covered facility with supporting surface structures.

A satellite image taken in August and obtained from Maxar shows construction is well underway of the underground facility as well as several supporting facilities.

The Air Force says the new facility “will provide a safer and more secure facility for the storage of U. S. Air Force (USAF) assets,” a reference to W78/Mk12A and W87/Mk21 warheads for the Minuteman III ICBMs deployed in Warren AFB’s 150 missile silos. In the future, if Congress agrees to fund it, the new W87-1 warhead will replace the W78. According to the Air Force:

“The primary interior walls of Maintenance and Storage Area are 4-foot thick reinforced concrete (RC) elements with 4-foot thick RC roof slabs. The primary wall and roof elements are surrounded by a 20-foot thick soil layer which is contained by a 3-foot thick RC wall and roof element layer. The heavy multilayered system sits on a 5-foot thick RC structural mat for support.”

The $144 million contract was awarded to Fluor Corporation by the U.S. Army Corps of Engineers in 2018. The ground-breaking ceremony took place on May 21, 2019 but substantial construction (of buildings) did not begin until the Spring of 2020. The president of Flour’s Government Group is Tom D’Agostino, who previously served as the undersecretary for nuclear security at the Department of Energy, administrator of the National Nuclear Security Administration (NNSA), and deputy administrator for defense programs. Construction was scheduled to take 40 months and be completed in 2022.

Construction of the underground storage facility at F.E. Warren AFB follows the completion in 2012 of a massive underground nuclear weapons storage facility at the Strategic Weapons Facility Pacific (SWFPAC) next to the Kitsap Naval Submarine Base. Underground storage facilities are also planned at other bases.

Some Missile Numbers Do Not Match Recent DOD China Report

U.S. Indo-Pacific Command recently gave a briefing about the challenges the command sees in the region. The briefing says China is the “Greatest Threat to Global Order and Stability” and presents a set of maps that portray a massive Chinese military buildup and very little U.S. capability (and no Allied capability at all) to counter it. With its weapons icons and a red haze spreading across much of the Pacific, the maps resemble a new version of the Cold War classic Red Storm Rising.

Unfortunately, the maps are highly misleading. They show all of China’s forces but only a fraction of U.S. forces operating or assigned missions in the Pacific.

There is no denying China is in the middle of a very significant military modernization that is increasing its forces and their capabilities. This is and will continue to challenge the military and political climate in the region. For decades, the United States enjoyed an almost unopposed – certainly unmatched – military superiority in the region and was able to project that capability against China as it saw fit. The Chinese leadership appears to have concluded that that is no longer acceptable and that the country needs to be able to defend itself.

In describing this development, however, the INDO-PACOM briefing slides make the usual mistake of overselling the threat and under-characterizing the defenses. Moreover, some of the Chinese missile forces listed in the briefing differ significantly from those listed in the recent DOD report on Chinese military developments. As military competition and defense posturing intensify, expect to see more of these maps in the future.

Apples, Oranges, and Cherry-Picking

The INDO-PACOM maps suffer from the same lopsided comparison and cherry-picking that handicapped the 2018 Nuclear Posture Review: it overplays the Chinese capabilities and downplays the U.S. capabilities (see image below). While he briefing maps includes all of China’s military forces, whether they are postured toward India or Russia, it only shows a small portion of U.S. forces. INDO-PACOM mapmakers may argue that it’s only intended to show the force level in the Western Pacific theater, but INDO-PACOM spans all of the Pacific and the maps ignore other significant U.S. forces that are operating in the region to oppose China.

The INDO-PACOM map gives the impression that the United States only has 175 fighter-jets, 12 bombers, 50 maritime patrol aircraft, 1 aircraft carrier, four amphibious assault ships, 12 modern multi-warfare warships, 10 submarines, and 2 THAAD missile defense batteries in the region to deter China. In reality, the U.S. military forces based or assigned missions in the INDO-PACOM area of responsibility are significantly greater. The map excludes everything based in Hawaii, in Alaska, on the U.S. west coast, and elsewhere in the continental United States with missions in the Pacific or forces rotating through bases in the Indo-Pacific region. Examples of mischaracterizations of U.S. forces include:

Fighter aircraft: The map lists only lists 175 fighter-jets, but Pacific Air Forces says it has “Approximately 320 fighter and attack aircraft are assigned to the command with approximately 100 additional deployed aircraft rotating on Guam.”

Bombers: The map lists only 12 bombers, but the United States has more than 150 bombers, many of which would be used to counter Chinese forces in a war. Moreover, those bombers are considerably more capable than Chinese bombers and are supported by tankers to provide unconstrained range in the Pacific, something Chinese bombers cannot do.

Submarines: The map lists only 10 U.S. submarines, but according to the U.S. Naval Vessel Register the U.S. Navy has more than three times that many (35) in the Pacific, including 25 attack submarines, 2 guide missile submarines, and 8 ballistic missile submarines (SSBNs) homeported in Pacific ports. The omission of the 8 Pacific-based SSBNs is particularly problematic given their important role of targeting China – and that they are assigned up to eight times more nuclear warheads than China has in its entire nuclear weapons stockpile.

Aircraft carriers: The map lists only one U.S. aircraft carrier, but according to the U.S. Naval Vessel Register the U.S. Navy has six aircraft carriers based in the Pacific (two of them in shipyard). Moreover, unlike China’s single aircraft carrier (a second is fitting out), U.S. carriers are large flat-tops with more aircraft.

Amphibious assault ships: The map shows four U.S. amphibious assault ships, but the U.S. Pacific Fleet says it operates six (although one was recently damaged by fire). Moreover, the amphibious assault ships are being upgraded to carry the F-35B VSTOL aircraft, significantly improving their strike capability.

Missile defense: The map shows only two THAAD batteries but does not mention the Ground Based Midcourse missile defense system in Alaska. Nor are missile defense interceptors deployed on cruisers and destroyers listed.

ICBMs: One of the most glaring omissions is that the maps do not show the United States has any ICBMs (the map also does not list U.S. SLBMs but nor does it list Chinese SLBMs). Although U.S. ICBMs are thought to be mainly assigned to targeting Russia and would have to overfly Russia to reach targets in China, that does not rule out they could be used to target China (Chinese ICBMs would also have to overfly Russia to target the continental United States). U.S. ICBMs carry more nuclear warheads than China has in its entire nuclear stockpile.

A modified map, apparently made available by U.S. Pacific Air Forces, is a little better because it includes Australian, Japanese, and South Korean forces. But it still significantly mischaracterizes the forces the United States has in the Pacific or are assigned missions in the region. Moreover, the new map does not include the yellow highlights showing “hypersonics” missiles and portion of aircraft, ships, and submarines that are modern (see modified map below).

Inconsistent Missile Numbers

The INDO-PACOM maps are also interesting because the numbers for Chinese IRBMs and MRBMs are different than those presented in the 2020 DOD report on Chinese military developments. INDO-PACOM lists 250 IRBMs/MRBMs, more than 100 missiles fewer than the DOD estimate. China has fielded one IRBM (DF-26), a dual-capable missile that exists in two versions: one for land-attack (most DF-26s are of this version) and one for anti-ship attack. China operates four versions of the DF-21 MRBM: the nuclear DF-21A and DF-21E, the conventional land-attack DF-21C, and the conventional anti-ship DF-21D.

There is also a difference in the number of SRBMs, which INDO-PACOM sets at 1,000, while the DOD report lists 600+. The 600+ could hypothetically be 1,000, but the INDO-PACOM number shows that the high-end of the 750-1,500 range reported by the 2019 DOD China report probably was too high.

A comparison (see table below) is complicated by the fact that the two reports appear to use slightly different terminology, some of which seems inconsistent. For example, INDO-PACOM lists “missiles” but the low IRBM/MRBM estimate suggests it refers to launchers. However, the high number of SRBMs listed suggest it refers to missiles.

2025 Projection

The projection made by INDO-PACOM for 2025 shows significant additional increases of Chinese forces, except in the number of SRBMs.

The ICBM force is expected to increase to 150 missiles from 100 today. That projection implies China will field an average of 10 new ICBMs each year for the next five years, or about twice the rate China has been fielding new ICBMs over the past two decades. Fifty ICBMs corresponds to about four new brigades. About 20 of the 50 new ICBMs are probably the DF-41s that have already been displayed in PLARF training areas, military parades, and factories. The remaining 30 ICBMs would have to include more DF-41s, DF-31AGs, and/or the rumored DF-5C, but it seems unlikely that China can add enough new ICBM brigade bases and silos in just five years to meet that projection.

The briefing also projects that 50 of the 150 ICBMs by 2025 will be equipped with “hypersonics.” The reference to “hypersonics” as something new is misleading because existing ICBMs already carry warheads that achieve hypersonic speed during reentry. Instead, the term “hypersonics” probably refers to a new hypersonic glide vehicle. It is unclear from the briefing if INDO-PACOM anticipates the new payload will be nuclear or conventional, but a conventional ICBM payload obviously would be a significant development with serious implications for crisis stability. Even if this expansion comes true, the entire Chinese ICBM force would only be one-third of the size of the U.S. ICBM force. Nonetheless, a Chinese ICBM force of 100-150 is still a considerable increase compared with the 40 or so ICBMs it operated two decades ago (see graph below).

The IRBM/MRBM force is projected to increase to 375, from 250 today. That projection assumes China will field 125 additional missiles over five years, or 25 missiles each year. That corresponds to a couple of new brigades per year, which seems high. Yet production is significant and IRBM launchers have been seen in several regions in recent years. The IRBM/MRBM force presumably would include the DF-17, DF-21, and the DF-26.

About 75-87 of the IRBM/MRBM force will be equipped with “hypersonics” by 2025, according to INDO-PACOM. That projection probably refers to the expected fielding of the DF-17 with a new glide-vehicle payload, although that would imply a lot of the new launcher (enough for 4-6 brigades). Another possibly is that a portion of other IRBMs/MRBMs (perhaps the DF-26) might also be equipped with the new payload or have their own version. China has presented the DF-17 as conventional but STRATCOM has characterized it as a “new strategic nuclear system.” Adding new hypersonics to IRBMs/MRBMs that are already mixing nuclear and conventional seems extraordinarily risky and likely to further exacerbate the danger of misunderstandings.

The status and projection for the surface fleet are also interesting. The INDO-PACOM briefing lists the total number of aircraft carriers, amphibious assault ships, and modern multi-warfare combatant vessels at 54, of which 46 are modern multi-warfare combatant vessels. The briefing doesn’t specify what is excluded from this count, but it differs significantly from the count in the DOD China report.

One of the puzzling parts of the INDO-PACOM briefing is the projection that China by 2025 will be operating four aircraft carriers for fixed-wing jets. China is currently operating one carrier with a second undergoing sea-trials. How China would be able to add another three carriers in five years is a mystery, not least because the third and fourth hulls are of a new and more complex design. The projection also doesn’t fit with the U.S. Office of Naval Intelligence, which predicts the third carrier won’t be commissioned until 2024.

Bombers are projected to increase from 175 today to 225 in 2025, an increase of nearly 30 percent. Since 2025 is probably too early for the new H-20 to become operational, the increase appears to only involve modern version of the H-6 bomber. Although the bomber force has recently been reassigned a nuclear mission, the majority of the Chinese bomber force will likely continue to be earmarked for conventional missions.

Submarines and surface vessels will also increase and some of them are being equipped with long-range missiles. Combined with the growing reach of ground-based ballistic missiles and air-delivered cruise missiles, this results in the INDO-PACOM maps showing a Chinese “anti-access area denial” (A2AD) capability bleeding across half of the Pacific well beyond Guam toward Hawaii. But A2AD is not a bubble and weakens significantly in areas further from Chinese shores.

Conclusion and Recommendations

The INDO-PACOM maps project China’s military modernization will continue at a significant pace over the next five years with increases in delivery platforms and capabilities. This will reduce the military advantage the United States has enjoyed over China for decades and further stimulate modernization of U.S. and allied military forces in the region. As forces grow, operations increase, and rhetoric sharpens, insecurity and potential incidents will increase as well and demand new ways of reducing tension and risks.

The Trump administration is correct that China should be included in talks about limiting forces and reducing tension. So far, however, the administration has not presented concrete ideas for what that could look like. Like the United States, China will not accept limits on its forces and operations without something in return that Beijing sees as being in its national interest. Although China is modernizing its nuclear forces and appears intent on increasing it further over the next decade, the force will remain well below the level of the United States and Russia for the foreseeable future. Insisting that China should join U.S.-Russian nuclear talks seems premature and it is still unclear what the United States would trade in return for what. In the near-term, it seems more important to try to reach agreements on limiting the increase of conventional forces and operations.

Unfortunately, the INDO-PACOM briefing does a poor job in comparing Chinese and U.S. forces and suffers from the same flaw as the 2018 Nuclear Posture Review by cherry-picking and mischaracterizing force levels. It is tempting to think that this was done with the intent to play up the Chinese threat while downplaying U.S. capabilities to assist public messaging and defense funding. But the Chinese military modernization is important – as is finding the right response. Neither the public nor the Congress are served by twisted comparisons.

It would also help if the Pentagon and regional commands would coordinate and streamline their public projections for Chinese modernizations. Doing so would help prevent misunderstandings and confusion and increase the credibility of these projections.

Finally, these kinds of projections raise a fundamental question: why does the Pentagon and regional military commands issue public threat projections at all? That should really be the role of the Director of National Intelligence, not least to avoid that U.S. public intelligence assessments suffer from inconsistencies, cherry-picking, and short-term institutional interests.

On this day, ten years ago, U.S. President Barack Obama and Russian President Dmitri A. Medvedev signed the New START treaty during a ceremony in Prague. The treaty capped the number of strategic missiles and heavy bombers the two countries could possess to 800, with no more than 700 launchers and 1,550 warheads deployed. The treaty entered into force in February 2011 and into effect in February 2018.

Twice a year, the two countries have exchanged detailed data on their strategic forces. Of that data, the public gets to see three sets of numbers: the so-called aggregate data of deployed launchers, warheads attributed to those launchers, and total launchers. Nine years of published data looks like this:

The latest set of this data was released by the U.S. State Department last week and shows the situation as of March 1, 2020. As of that date, the two countries possessed a combined total of 1,554 strategic missiles and heavy bombers, of which

1,140 launchers were deployed with 2,699 warheads (note: the warhead number is actually about 100 too high because each deployed bomber is counted as one weapon even though bombers don’t carry weapons under normal circumstances).

Compared with September 2019, the data shows the two countries combined cut 3 strategic launchers, reduced deployed strategic launchers by 41, and reduced the number of deployed strategic warheads by 103. Of these numbers, only the “3” is real; the other changes reflect natural fluctuations as launchers move in and out of maintenance or are being upgraded.

Compared with February 2011, the data shows the two countries combined have cut 435 strategic launchers, reduced deployed strategic launchers by 263, and reduced the number of deployed strategic warheads by 638. While important, it’s important to remind that this warhead reduction is but a fraction (less than 8 percent) of the estimated 8,110 warheads that remain in the two countries combined nuclear weapons stockpiles (less than 6 percent if counting their total combined inventories of 12,170 stockpiled and retired (but yet to be dismantled) warheads).

The United States

The data shows the United States currently possessing 800 strategic launchers, of which 655 are deployed with 1,373 warheads attributed to them. This is a reduction of 13 deployed strategic launchers and 3 deployed strategic warheads over the past 6 months. These are not actual reductions but reflect normal fluctuations caused by launchers moving in and out of maintenance. The United States has not reduced its total inventory of strategic launchers since 2017.

Compared with February 2011, the United States has reduced its inventory of strategic launchers by 324, deployed launchers by 227, and deployed strategic warheads by 427. While important, the warhead reduction represents only a small fraction (about 11 percent) of the 3,800 warheads that remain in the U.S. stockpile (a little over 7 percent if counting total inventory of 5,800 stockpiled and retired (but yet to be dismantled) warheads).

The Russian Federation

The New START data shows Russia with an inventory of 764 strategic launchers, of which 485 are deployed with 1,326 warheads attributed to them. Compared with six months ago, this is a reduction of 28 deployed launchers and 100 deployed strategic warheads and reflects launcher maintenance and upgrade work to new systems.

Compared with February 2011, Russia has cut its inventory of strategic launchers by 111, deployed launchers by 36, and deployed strategic warheads by 211. This modest reduction represents less than 5 percent of the estimated 4,310 warheads that remain in Russia’s nuclear weapons stockpile (less than 4 percent if counting the total inventory of 6,370 stockpiled and retired (but yet to be dismantled) Russian warheads).

The Russian reductions accomplished under New START are smaller than the U.S. reductions because Russia had fewer strategic forces than the United States when the treaty entered into force in 2011.

Build-up, What Build-up?

With frequent claims by U.S. officials and nuclear weapons advocates that Russia is increasing its nuclear arsenal, it is interesting that despite a significant modernization program, the New START data shows this increase is not happening in the size of Russia’s strategic nuclear forces.

On the contrary, the New START data shows that Russia now has 170 deployed strategic launchers fewer than the United States, a number that exceeds the size of an entire US Air Force ICBM wing. The Russian launcher deficit has been growing by more than one-third since the lowest point of 125 in February 2018.

The Russian military is trying to compensate for this launcher disparity by increasing the number of warheads that can be carried on newer missiles replacing older types. Most of these warheads are not deployed on the missiles under normal circumstance but stored and could potentially be uploaded onto launchers in a crisis. The United States also has such an upload capability for its larger inventory of launchers and therefore is not at a strategic disadvantage.

Two of Russia’s new strategic nuclear weapons (Avangard and Sarmat) are covered by New START. Other types are in relatively small numbers and do not appear capable of upsetting the strategic balance. The treaty includes provisions for including new weapon types.

Inspections and Notifications

In addition to the New START data, the U.S. State Department also recently updated its overview of the status of the on-site inspections and notification exchanges that are part of the treaty’s verification regime.

Since February 2011, U.S. and Russian inspectors have carried out 328 on-site inspections of each other’s strategic nuclear forces and exchanged 19,852 notifications of launcher movements and activities. Four inspections happened this year before activities were temporarily halted due to the Coronavirus.

This inspection and notification regime and record are crucial parts of the treaty and increasingly important for U.S.-Russian strategic relations as other treaties and agreements have been scuttled.

But time is now also running out for New START with only a little over 10 months remaining before the treaty expires on February 5, 2021.

Russia and the United States can extend the New START treaty by up to 5 more years. It is essential both sides act responsibly and do so to preserve this essential agreement.

One year from today, on February 5, 2021, the New START treaty will expire, unless the United States and Russia act to extend the last nuclear arms control agreement for an additional five years.

No matter your political orientation, treaty extension is a no-brainer – for at least six primary reasons.

1. New START keeps nuclear arsenals in check. If the treaty expires, there will be no constraints on US or Russian strategic arsenals for the first time since 1972. It would remove caps on how many strategic nuclear missiles and bombers the two sides can own and how many warheads that are carried on them. This means that Russia could quickly upload about a thousand new warheads onto its deployed missile arsenal–without adding a single new missile. The United States could upload even more because it has more missiles and bombers than Russia (see table below). And both sides could begin to increase their arsenals, risking a new nuclear arms race.

At a time when NATO-Russian relations are at their lowest since the end of the Cold War, when long-term predictability is more important than in the past three decades, allowing New START constraints to expire is obviously not in the US strategic interest or that of its allies. Very simply, New START is a good deal for both the United States and Russia; it cannot be allowed to expire without replacing it with something better.

2. New START force level is the basis for current nuclear infrastructure plans. Both the United States and Russia have structured their nuclear weapons and industry modernization plans on the assumption that the New START force level will continue, or at least not increase. If New START falls away, those assumptions and modernization plans will have to be revised, resulting in significant additional costs that neither Russia nor the United States can afford.

3. New START offers transparency and predictability in an unstable world. Under the current treaty, the United States receives a notification every time a Russian missile is deployed, every time a missile or bomber moves between bases, and every time a new missile is produced. Without these notifications, the United States would have to spend more money and incur significant risks to get the exact same information through National Technical Means (i.e. satellites and other forms of site monitoring). Russia benefits in the same way.

Why would we willingly give all that up – to get absolutely nothing in return (and actually pay a steep price for giving it up)?

4. New START has overwhelming bipartisan support––even among Trump voters. Not only is extension a foreign policy priority for Democrats, but polling data indicates that approximately 70% of Trump voters across the country are in favor of extending New START.

Additionally, senior military leaders like the Vice Chairman of the Joint Chiefs of Staff and the commander of Air Force Global Strike Command have expressed support for the treaty. Even one of Trump’s own political appointees, Deputy Secretary of Defense for Policy David Trachtenberg, has testified that that “the transparency and verification requirements of the New START Treaty are a benefit” to the security of the United States.

5. We won’t get another chance. If New START expires next year, arms control between Russia and the United States as we know it is effectively over. Given the underlying East-West tensions and upcoming dramatic governance shifts in both the United States and Russia, there appears to be little interest or bandwidth available on either side in negotiating a new and improved treaty.

Moreover, although future arms control must attempt to incorporate other nuclear-armed states, efforts to do so should not jeopardize New START.

At risk of stating the obvious, negotiating a new treaty is exponentially more difficult than extending an existing one.

6. It’s easy. Extension of New START doesn’t require Congressional legislation or Senate ratification. All it takes is a presidential stroke of a pen. And at the end of 2019, Putin offered to immediately extend the treaty “without any preconditions.” President Trump should immediately take him up on his offer; as of today, he has exactly one year left to do so. But don’t wait till the last minute! Get it done!

The US Navy has now deployed the new W76-2 low-yield Trident submarine warhead. The first ballistic missile submarine scheduled to deploy with the new warhead was the USS Tennessee (SSBN-734), which deployed from Kings Bay Submarine Base in Georgia during the final weeks of 2019 for a deterrent patrol in the Atlantic Ocean.

The W76-2 warhead was first announced in the Trump administration’s Nuclear Posture Review (NPR) unveiled in February 2018. There, it was described as a capability to “help counter any mistaken perception of an exploitable ‘gap’ in U.S. regional deterrence capabilities,” a reference to Russia. The justification voiced by the administration was that the United States did not have a “prompt” and useable nuclear capability that could counter – and thus deter – Russian use of its own tactical nuclear capabilities.

We estimate that one or two of the 20 missiles on the USS Tennessee and subsequent subs will be armed with the W76-2, either singly or carrying multiple warheads. Each W76-2 is estimated to have an explosive yield of about five kilotons. The remaining 18 missiles on each submarine like the Tennessee carry either the 90-kiloton W76-1 or the 455-kiloton W88. Each missile can carry up to eight warheads under current loading configurations.

The first W76-2 (known as First Production Unit, or FPU) was completed at Pantex in February 2019. At the time, NNSA said it was “on track to complete the W76-2 Initial Operational Capability warhead quantity and deliver the units to the U.S Navy by the end of Fiscal Year 2019” (30 September 2019). We estimate approximately 50 W76-2 warheads were produced, a low-cost add-on to improved W76 Mod 1 strategic Trident warheads which had just finished their own production run.

The W76-2 Mission

The NPR explicitly justified the W76-2 as a response to Russia allegedly lowering the threshold for first-use of its own tactical nuclear weapons in a limited regional conflict. Nuclear advocates argue that the Kremlin has developed an “escalate-to-deescalate” or “escalate-to-win” nuclear strategy, where it plans to use nuclear weapons if Russia failed in any conventional aggression against NATO. The existence of an actual “escalate-to-deescalate” doctrine is hotly debated, though there is evidence that Russia has war gamed early nuclear use in a European conflict.

Based upon the supposed “escalate-to-deescalate” doctrine, the February 2018 NPR claims that the W76-2 is needed to “help counter any mistaken perception of an exploitable ‘gap’ in U.S. regional deterrence capabilities.” The National Nuclear Security Administration (NNSA) has further explained that the “W76-2 will allow for tailored deterrence in the face of evolving threats” and gives the US “an assured ability to respond in kind to a low-yield nuclear attack.”

Consultants who were involved in producing the NPR have suggested that “[Russian President] Putin may well believe that the United States would not respond with strategic warheads that could cause significant collateral damage” and “that Moscow could conceivably engage in limited nuclear first-use without undue risk…”

There is no firm evidence that a Russian nuclear decision regarding the risk involved in nuclear escalation is dependent on the yield of a US nuclear weapon. Moreover, the United States already has a large number of weapons in its nuclear arsenal that have low-yield options – about 1,000 by our estimate. This includes nuclear cruise missiles for B-52 bombers and B61 gravity bombs for B-2 bombers and tactical fighter jets.

Yes, but – so the W76-2 advocates argue – these low-yield warheads are delivered by aircraft that may not be able to penetrate Russia’s new advanced air-defenses. But the W76-2 on a Trident ballistic missile can. Nuclear advocates also argue the United States would be constrained from employing fighter aircraft-based B61 nuclear bombs or “self-deterred” from employing more powerful strategic nuclear weapons. In addition to penetration of Russian air defenses, there is also the question of NATO alliance consultation and approval of an American nuclear strike. Only a low-yield and quick reaction ballistic-missile can restore deterrence, they say. Or so the argument goes.

All of this sounds like good old-fashioned Cold War warfighting. In the past, every tactical nuclear weapon has been justified with this line of argument, that smaller yields and “prompt” use – once achieved through forward European basing of thousands of warheads – was needed to deter. Now the low-yield W76-2 warhead gives the United States a weapon its advocates say is more useable, and thus more effective as a deterrent, really no change from previous articulations of nuclear strategy.

The authors of the NPR also saw the dilemma of suggesting a more usable weapon. They thus explained that the W76-2 was “not intended to enable, nor does it enable, ‘nuclear war-fighting.’ Nor will it lower the nuclear threshold.” In other words, while Russian low-yield nuclear weapons lower the threshold making nuclear use more likely, U.S. low-yield weapons instead “raise the nuclear threshold” and make nuclear use less likely. Undersecretary of Defense for Policy John Rood even told reporters that the W76-2 would be “very stabilizing” and in no way supports U.S. early use of nuclear weapons, even though the Nuclear Posture Review explicitly stated the warhead was needed for “prompt response” strike options against Russian early use of nuclear weapons.

“Prompt response” means that strategic Trident submarines in a W76-2 scenario would be used as tactical nuclear weapons, potentially in a first use scenario or immediately after Russia escalated, thus forming the United States’ own “escalate-to-deescalate” capability. The United States has refused to rule out first use of nuclear weapons.

Since the United States ceased allocating some of its missile submarines to NATO command in the late-1980s, U.S. planners have been reluctant to allocate strategic ballistic missiles to limited theater tasks. Instead, NATO’s possession of dual-capable aircraft and increasingly U.S. long-range bombers on Bomber Assurance and Deterrence Operations (BAAD) – now Bomber Task Force operations – have been seen as the most appropriate way to slow down regional escalation scenarios. The prompt W76-2 mission changes this strategy.

In the case of the W76-2, carried onboard a submarine otherwise part of the strategic nuclear force, amidst a war Russia would have to determine that a tactical launch of one or a few low-yield Tridents was not, in fact, the opening phase of a much larger escalation to strategic nuclear war. Thus, it seems inconceivable that any President would approve employment of the W76-2 against Russia; deployment on the Trident submarine might actually self-deter.

Though almost all of the discussion about the new W76-2 has focused on Russia scenarios, it is much more likely that the new low-yield weapon is intended to facilitate first-use of nuclear weapons against North Korea or Iran. The National Security Strategy and the NPR both describe a role for nuclear weapons against “non-nuclear strategic attacks, and large-scale conventional aggression.” And the NPR explicitly says the W76-2 is intended to “expand the range of credible U.S. options for responding to nuclear or non-nuclear strategic attack.” Indeed, nuclear planning against Iran is reportedly accelerating, B-2 bomber attacks are currently the force allocated but the new W76-2 is likely to be incorporated into U.S. Central Command (CENTCOM) war planning.

Cheap, Quick, Simple, But Poorly Understood

In justifying the W76-2 since the February 2018 NPR, DOD has emphasized that production and deployment could be done fast, was simple to do, and wouldn’t cost very much. But the warhead emerged well before the Trump administration. The Project Atom report published by the Center for Strategic and International Studies in 2015 included recommendations for a broad range of low-yield weapons, including on long-range ballistic missiles. And shortly after the election of President Trump, the Defense Science Board’s defense priority recommendations for the new administration included “lower yield, primary-only options.” (This refers to the fact that the W76-2 is essentially little different than the strategic W76-1, “turning off” the thermonuclear secondary and thus facilitating rapid production.)

Initially, the military interest in a new weapon seemed limited. When then STRATCOM commander General John E. Hyten (now Vice Chairman of the Joint Chiefs of Staff) was asked during Congressional hearings in March 2017 about the military need for lower-yield nuclear weapons, he didn’t answer with a yes or no but explained the U.S. arsenal already had a wide range of yields:

Rep. Garamendi: The Defense Science Board, in their seven defense priorities for the new administration, recommended expanding our nuclear options, including deploying low yield weapons on strategic delivery systems. Is there a military requirement for these new weapons?

Gen. Hyten: So Congressman, that’s a great conversation to tomorrow when I can tell you the details [in closed classified session], but from a — from a big picture perspective in — in a public hearing, I can tell you that our force structure now actually has a number of capabilities that provide the president of the United States a variety of options to respond to any numbers of threats.

Later that month, in an interview at the Military Reporters and Editors Conference, Hyten elaborated further that the United States already had very flexible military capabilities to respond to Russian use of tactical nuclear weapons:

John Donnelly (Congressional Quarterly Roll Call): The Defense Science Board, among others, has advocated development of new options for maneuvering lower yield nuclear warheads instead of just air delivered, talking basically about ICBM, SLBM. The thinking, I think, is that given the Russian escalate to win, if you like, or escalate to deescalate doctrine, the United States needs to have more options. What do you think about, that is my question. Especially in light of the fact that there are those who are concerned that this further institutionalizes the idea that you can fight and maybe even win a limited nuclear war.

Gen. Hyten: …we’re going to look at that in the Nuclear Posture Review over the next six months. I think it’s a valid question to ask, but I’ll just tell you what I’ve said in public up until this point, and as we go into the Nuclear Posture Review.

…in the past and where I am right now is that I’ll just say that the plans that we have right now, one of the things that surprised me most when I took command on November 3 was the flexible options that are in all the plans today. So we actually have very flexible options in our plans. So if something bad happens in the world and there’s a response and I’m on the phone with the Secretary of Defense and the President and the entire staff, which is the Attorney General, Secretary of State and everybody, I actually have a series of very flexible options from conventional all the way up to large-scale nuke that I can advise the President on to give him options on what he would want to do.

So I’m very comfortable today with the flexibility of our response options. Whether the President of the United States and his team believes that that gives him enough flexibility is his call. So we’ll look at that in the Nuclear Posture Review. But I’ve said publicly in the past that our plans now are very flexible.

And the reason I was surprised when I got to STRATCOM about the flexibility, is because the last time I executed or was involved in the execution of the nuclear plan was about 20 years ago and there was no flexibility in the plan. It was big, it was huge, it was massively destructive. … We now have conventional responses all the way up to the nuclear responses, and I think that’s a very healthy thing. So I’m comfortable with where we are today, but we’ll look at it in the Nuclear Posture Review again.

During the Trump NPR process, however, the tone changed. Almost one year to the day after Hyten said he was comfortable with the existing capabilities, he told lawmakers he needed a low-yield warhead after all: “I strongly agree with the need for a low-yield nuclear weapon. That capability is a deterrence weapon to respond to the threat that Russia, in particular, is portraying.”

While nuclear advocates were quick to take advantage of the new administration to get approval for new nuclear weapons they said were needed to now respond to Russia’s supposed “escalate-to-deescalate” strategy, efforts to engage Moscow to discuss nuclear strategy and their impact on nuclear arsenals are harder to find. See, for example, this written correspondence between Representative Susan Davis and General Hyten:

Rep. Davis: Have you ever had a discussion with Russia about their nuclear posture, and in particular an escalate-to-de-escalate (E2D) strategy, which the Nuclear Posture Review claims is part of Russia’s nuclear doctrine? How did they respond? Do you view this doctrine as offensive or defensive in nature?

Gen. Hyten: I would like to have such a discussion, but I have never had a conversation with Russia about their nuclear posture.

During the Fiscal Year 2019 budget debate, Democrats argued strongly against the new low-yield W76-2, and opposition increased on Capitol Hill after the 2018 mid-term elections gave Democrats control of the House of Representatives. But given the relatively low cost of the W76-2, and the fact that it was conveyed as merely an “add-on” to an already hot W76 production line, little progress was made by opponents. Reluctantly accepting production of the warhead in the FY 2019 defense budget, opponents again in August 2019 tried to block funding in the FY 2020 defense budget arguing the new warhead “is a dangerous, costly, unnecessary, and redundant addition to the U.S. nuclear arsenal,” and that it “would reduce the threshold for nuclear use and make nuclear escalation more likely.” When the Republican Senate majority refused to accept the House’s sense, Democrats caved.

Just a few months later, the first W76-2 warheads sailed into the Atlantic Ocean onboard the USS Tennessee.

Should the U.S. Air Force withdraw the roughly 50 B61 nuclear bombs it stores at the Incirlik Air Base in Turkey? The question has come to a head after Turkey’s invasion of Syria, Erdogan’s increasingly authoritarian leadership and deepening discord with NATO, Trump’s inability to manage U.S. security interests in Europe and the Middle East, and war-torn Syria only a few hundred miles from the largest U.S. nuclear weapons storage site in Europe.

According to The New York Times, State and Energy Department (?) officials last weekend quietly reviewed plans for evacuating the weapons from Incirlik. “Those weapons, one senior official said, were now essentially Erdogan’s hostages. To fly them out of Incirlik would be to mark the de facto end of the Turkish-American alliance. To keep them there, though, is to perpetuate a nuclear vulnerability that should have been eliminated years ago.”

That review is long overdue! [Actually, I’ve heard there have been several reviews and a lively internal debate since the 2016 coup attempt.] Some of us have been calling for withdrawal for years (see here and here), but officials have resisted saying it wasn’t as bad as it looked and that the deployment still served a purpose. They were wrong. And by waiting so long to act, the United States has painted itself into a corner where the choice between nuclear security and abandoning Turkey has become unnecessarily stark and urgent.

The situation is even more untenable because Incirlik in just a few years is scheduled to receive a large shipment of the new B61-12 guided nuclear bomb, which would be a recommitment to nuclear deployment in Turkey.

This year is the 60th anniversary of the first deployment of nuclear weapons to Turkey. It is time to bring them home.

Nuclear Weapons At Incirlik

The specific reference in the New York Times article made by officials to nuclear weapons at Incirlik is the most recent and authoritative confirmation that nuclear weapons are still stored at the base. That confirms what I have been hearing and sources at US Air Forces Europe confirmed the report, telling William Arkin the weapons are still there.  There have been rumors the weapons were removed after the coup attempt in 2016 (and some really bad disinformation that they had been moved to Romania). All of those rumors were wrong. An article on the official Incirlik Air Base web site even confirms that the mission of the 39th Operations Support Squadron is “to orchestrate and control US, Turkish, and coalition forces operating at Incirlik Airbase in the execution of full-spectrum airpower and nuclear deterrent operations” (emphasis added). Given that the article will likely be removed now that I have pointed this out, it is reproduced in full below:

I have estimated for the past several years that the Air Force stores about 50 B61 nuclear gravity bombs at Incirlik, one-third of the 150 nuclear weapons currently deployed in Europe (see figure below). This estimate has been used by a wide range of news reports and commentators. The number of bombs at Incirlik has decreased over the past two decades from 90 in 2000. In those days, 40 of the 90 bombs were earmarked for delivery by Turkish F-16s. Those 40 bombs used to be stored in 6 vaults at both Akinci AB and Balikesir AB (20 at each) until they were moved to Incirlik when the US Air Force withdrew its Munition Support Squadrons from the Turkish bases in 1996. The 40 “Turkish” bombs remained at Incirlik until around 2005 when they were shipped back to the United States as part of the Bush administration’s unilateral nuclear reduction in Europe.

 

The remaining 50 bombs are for use by US jets, even though Turkey never allowed the US Air Force to permanently base fighter-squadrons at Incirlik. Jets would have to fly in during a crisis to pick up the weapons or they would have to be shipped to other locations before use. As a result, the nuclear posture at Incirlik has been more a storage site than a fighter-bomber base during the past two decades.

Although the Turkish participation in the NATO nuclear sharing mission was lessened (some would say mothballed) by the withdrawal of the “Turkish” weapons, the Turkish F-16s continued to serve a nuclear role. Despite local reports that F-16s never had a nuclear role, the US Air Force in 2010 informed Congress that “Turkey uses Turkish F-16s to execute their nuclear mission,” and that some of the F-16s would be upgraded to be able to deliver the new B61-12 bomb until the F-35A could take over the nuclear strike mission in the 2020s. That is now not going to happen after the Trump administration canceled the F-35 sale.

In 2015, satellite images revealed construction of a new security perimeter around most of the aircraft shelters with nuclear weapons storage vaults. Of the 25 shelters that originally were equipped with vaults, only 21 were included in the new security area with a capacity to store up to a maximum of 84 nuclear bombs. Normally only about two bombs are stored in each vault, for a total of inventory of 40-50 bombs at Incirlik.

 

As recently as last month, Vice Chief Staff of the Air Force, Gen. Stephen W. Wilson, visited Incirlik and was given tours of the various functions and facilities at the base. One of these was Protective Aircraft Shelter H-2 inside the “NATO Area” where he spoke to members of the 39^th Security Force that protects the nuclear weapons (see below). He was likely also shown the inside of the shelter and the weapons in the vault.

Recent Activities

If the Air Force decided to withdraw the B61 bombs from Incirlik, it would look pretty much like activities captured by Maxar’s satellites in 2019 and 2017. Those images show what appears to be either actual nuclear weapons movements or training to remove them.

One photo from March 22, 2019, shows a C-17 transport aircraft – likely from the 4^th Airlift Squadron of the 62^nd Airlift Wing at Joint Base Lewis-McChord in Washington – parked right outside the main gate to the NATO Area. The 4^th Airlift Squadron, which is the only unit in the Air Force that is qualified to airlift nuclear weapons, flies Prime Nuclear Airlift Force (PNAF) and Emergency Nuclear Airlift Operations (ENAO) missions (see images below).

 

The satellite image shows the C-17 and gate area surrounded by armored vehicles and armed guards of the 39^th Security Force as well as technicians to protect and carry out the weapon movement. One of the unique vehicles seen is an 18-meter truck lined up with the loading pad of the C-17. The same type of truck can be seen parked at the weapons maintenance unit building a few months later (see image below).

 

Another set of Maxar satellite photos of a possible nuclear weapons movement or exercise is from December 2017. A Nuclear Security Inspection that year (and 2014)  reportedly included weapons emergency evacuation drills. The scenario on the 2017 image is similar to that on the 2019 image: a C-17 parked outside the gate, security vehicles surrounding the scene, and transporters for moving weapons. But the 2017 photos are unique because they were taken moments apart as the satellite passed overhead. As a result, movements become visible: On the first image, a possible weapons trailer towed behind a truck in a column of armored security vehicles is moving toward the outer gate of the NATO Area. On the second photo, the column has passed through the gate onto the tarmac and the towed trailer is turning toward the rear of the C-17. The aircraft shadow shows the loading ramp is open and ready to receive the weapons (see image below).

 

The Task At Hand: Withdraw The Weapons!

The B61 nuclear bombs at Incirlik should have been withdrawn long ago but tradition, Cold War thinking, and bureaucratic inertia prevented officials from doing the right thing. Now things have come to a head where the United States is faced with the choice of securing its weapons or be seen as abandoning Turkey.

Withdrawing the weapons does not, of course, mean the United States is abandoning Turkey. That relationship is already in serious trouble and keeping the weapons at Incirlik based on the idea that it will somehow counterweight Turkey’s further drift away from NATO is probably an illusion. That boat seems to have sailed; the relationship is likely to deteriorate whether or not there are nuclear weapons at Incirlik. That is the reality the Air Force must relate to now.

 

Another argument against withdrawal will be that moving them out of Turkey will cause the other members of the so-called nuclear sharing arrangement (Belgium, Germany, Holland, Italy) to question why they should continue to store U.S. nuclear weapons. Withdrawal from Turkey could, so the argument goes, trigger a domino effect of withdrawal from other countries as well.

But the withdrawal of U.S. nuclear bombs from Greece in 2001 and from England five years later did not cause the other countries to demand withdrawal as well or the collapse of NATO. If they truly believe deployment of U.S. nuclear weapons is important for NATO security, then they will stay. If the mission falls with withdrawal from Turkey, then they obviously don’t think it’s important and the weapons should be withdrawn from all the countries anyway. The U.S. extended deterrence posture in Europe can adequately be maintained with advanced conventional forces backed up by strategic forced in the background.

The B61 bombs at Incirlik could easily be dispersed to empty storage vaults in the other countries. Space is not a problem. There are a total of 96 empty weapon slots in the active WS3 vaults in Belgium, Germany, Holland, and Italy. Moreover, there are 25 empty and inactive WS3 vaults with room for 100 bombs at RAF Lakenheath. But public and parliamentary opposition would likely prevent increasing the number of nuclear bombs stored in those countries. If the order goes out to evacuate Incirlik, it seems more likely the bombs would be returned to the United States.

There will be some people who will argue that deteriorating relations with Russia and Moscow’s alleged increased reliance on a so-called “escalate-to-deescalate” strategy of using tactical nuclear weapons first prevent the United States from reducing – certainly withdrawing – its tactical nuclear weapons from Europe. Those are curiously the same people who also argue that the United States should deploy a new low-yield warhead on its strategic submarines and a new nuclear cruise missile on its attack submarines to better counter Russian tactical nuclear weapons – a thinking that was recently endorsed by the Trump administration’s Nuclear Posture Review. That seems to signal to the European allies that the United States actually no longer believes the deployment of B61 nuclear bombs in Europe is credible and that other and better weapons are needed.

 

Whatever one might think about U.S. tactical nuclear weapons in Europe, Turkey is no longer an acceptable location. Erdogan’s confrontational and authoritarian leadership is rapidly undermining Turkey’s status as a reliable NATO ally, and the deteriorating security situation in the region presents a real physical threat to the weapons at Incirlik. That threat is real and the U.S. military sees it as real. So much so that an extra security force squadron deployed to Incirlik from Aviano Air Base in Italy to beef up nuclear security in response to “regional turmoil and government instability” according to USAF source, and Ohio Army National Guard military police reportedly were dispatched to Incirlik specifically to increase base security.

The security threat to the weapons at Incirlik is urgent and the continued deployment of nuclear weapons at the location is unjustifiable and incompatible with U.S. nuclear security standards. If you don’t believe that, ask yourself this question: If there were no U.S. nuclear weapons in Turkey and someone asked for them to be deployed to Incirlik, would the Pentagon approve?

I doubt it. It’s time to face reality and withdraw the weapons from Turkey before they have to be evacuated under fire.

The latest data on US and Russian strategic nuclear forces limited by the New START treaty shows the treaty is serving its intended purpose of keeping a lid on the two countries’ arsenals.

The data was published by the State Department yesterday.

Despite deteriorating relations and revival of “Great Power Competition” strategies, the data shows neither side has increased deployed strategic force levels in the past year.

The data set released is the last before the New START treaty enters its final year before it expires in February 2021. The treaty can be extended for another five years by the stroke of a pen, but arms control opponents in Washington and Moscow are working hard to prevent this from happening. If they succeed, the world’s two largest nuclear arsenals will be completely unregulated for the first time since the 1970s.

By The Numbers

The latest data shows that the United States and Russia combined, as of March 1^st, 2019, deployed a total of 1,181 strategic launchers (long-range ballistic missiles and heavy bombers) with a total of 2,802 warheads attributed to them (see chart below). That is very close to the combined forces they deployed six months ago. These two arsenals constitute more strategic launchers and warheads than all the world’s other seven nuclear-armed states possess combined.

For Russia, the data shows 513 deployed strategic launchers with 1,426 warheads. That’s a slight decrease of 11 launchers and 3 warheads compared with March 2019. Russia is currently 187 launchers and 124 warheads below the treaty limit for deployed strategic weapons.

The United States deploys 668 strategic launchers with 1,376 warheads attributed to them, according to the new data, or a slight increase of 12 launchers and 11 warheads compared with March 2019. The United States is currently 32 launchers and 174 warheads below the treaty limit for deployed strategic weapons.

These increases and decreases since March 2019 are normal fluctuations in the arsenals due to maintenance and upgrades and do not reflect an increase or decrease of the force structure or threat level.

It is important to remind, that the Russian and US nuclear forces reported under New START are only a portion of their total stockpiles of nuclear weapons, currently estimated at 4,330 warheads for Russia and 3,800 for the United States (6,500 and 6,185, respectively, if also counting retired warheads awaiting dismantlement). Both sides could upload many hundreds of warheads extra on their launchers if New START was allowed to expire.

Build-Up, What Build-Up?

Both Russia and the United States are engaged in significant modernization programs to extend and improve their strategic nuclear forces. So far, however, these programs largely follow the same overall structure and are unlikely to significantly change the strategic balance of those forces. The New START data shows the treaty is serving to keep a lid on those modernization plans.

That said, both countries are working on modifications to their strategic nuclear arsenals. Russia has been working for a long time – even before New START was signed – to develop exotic intercontinental-range weapons to overcome US ballistic missile defense systems. These exotic weapons, which are not yet deployed or covered by the treaty, include a ground-launched nuclear-powered cruise missile (Burevestnik) and a submarine-launched torpedo-like drone (Poseidon). The Trump administration is complaining these new weapons should be included in the treaty. A third weapon, an  ICBM-launched glide-vehicle commonly known as Avangard, is close to initial deployment and will be accountable under the treaty but would likely replace existing deployed warheads. All of these weapons are limited in numbers and insufficient to change the overall strategic balance or challenge extension of New START. The treaty provides for adding new weapon types if agreed by the two parties, although neither side has formally proposed to do so.

Russia is not at an advantage in terms of overall strategic nuclear forces and the new data shows it does not appear to try to close the significant gap that exists in the number of deployed strategic launchers – 155 in US favor by the latest count (up 23 launchers from March 2019). To put things in perspective, 155 launchers are the equivalent of an entire US ICBM wing, or more than seven Ohio-class ballistic missile submarines fully loaded, or more than twice the size of the entire US nuclear bomber fleet. If the tables were turned, US officials and hardliners would certainly be complaining about a Russian advantage. Given this launcher disparity, one could also suspect that Russia might seek to retain more non-deployed launchers for potential redeployment to be able to rapidly increase the force if necessary. Instead, the New START data shows that Russia has continued to decrease its non-deployed launchers (down 12 since March 2019).

Instead of trying to close the launcher gap, Russia is compensating for the disparity by maximizing warhead loadings on its new missiles to be able to keep overall parity with the United States. Since 2016, the New START data indicates that Russia has been forced to reduce the normal warhead loading on some of its ballistic missiles in order to meet the treaty limit for deployed warheads. This demonstrates New START has a real constraining effect on Russian deployed strategic forces.

Having said that, Russia could potentially – like the United States – upload large numbers of non-deployed nuclear warheads onto deployed strategic launchers if a decision was made to break out of the New START limits or the treaty was allowed to expire in 2021. Those launchers would include initially bombers, then sea-launched ballistic missiles, and in the longer term the ICBMs. Significantly increasing the force structure, however, would take decades to achieve because both sides have based their long-term planning on the assumption that the New START force level would continue.

The United States has dismantled and converted more launchers than Russia because the United States had more of them when the treaty was signed, not because Washington was handed a “bad deal,” as some defense hardliners have claimed. But Russia has complained – including in an unprecedented letter to the US Congress – that it is unable to verify that launchers converted by the US to a conventional role cannot be returned to nuclear use. The New START treaty does not require irreversibility, however, and the US insists the conversions have been carried out in accordance with the treaty provisions that Russia agreed to when it signed the treaty.

The Russia complaints about converted launchers and the US complaints about incorporating new strategic weapons are issues that should be resolved in the treaty’s Bilateral Consultative Committee (BCC).

Verification and Notifications

Although not included in the formal aggregate data, the State Department has also disclosed the total number of inspections and notifications conducted under the treaty. Since February 2011, this has included 313 onsite inspections  (25 this year) and 18,803 notifications (2,387 last 12 months). This data flow is essential to providing confidence and reassurance that the strategic force level of the other side indeed is what they say it is. It also provides each side invaluable insight into structural and operational matters that complements and expands what is possible to ascertain with national technical means.

What Now?

Although bureaucrats and Cold Warriors in both Washington and Moscow currently are busy raising complaints and uncertainties about the New START treaty, there is no way around the basic fact: New START is strongly in the national security interest of both countries – as well as that of their allies.

But the treaty expires in February 2021 and the two sides could – if their leadership was willing to act – extend it with the stroke of a pen.

Unfortunately, Russian complaints that it is incapable of confirming US conversion of strategic launchers, US complaints that new exotic Russian weapons circumvent the treaty, Russia’s violation and the US decision to withdraw from the INF treaty, as well as the growing political animosity and bickering between East and West, have combined to increase the pressure on New START and put extension in doubt.

This all captures well the danger of Cold War mindsets where nationalistic bravado and chest-thumping override deliberate rational strategy for the benefit of national and international security. Bad times are not an excuse for sacrificing treaties but reminders of the importance of preserving them. Arms limitation treaties are not made with friends (you don’t have to) but with potential adversaries in order to limit their offensive nuclear forces and increase transparency and verification. If officials focus on complaining and listing problems, that’s what they’ll get.

It is essential that Russia and the United States decide now to extend the New START treaty. Without it, the two sides will switch into a worst-case-scenario mindset for long-term planning of strategic forces that could well trigger a new nuclear arms race.

MacArthur Foundation, the New Land Foundation, the Ploughshares Fund, and the Prospect Hill Foundation. The statements made and views expressed are solely the responsibility of the authors.

Last week, on the 74th anniversary of the Hiroshima and Nagasaki bombings, many took time to reflect upon the destruction caused by the only uses of nuclear weapons in wartime. But not the New York Times’ Bret Stephens, who took the opportunity to argue in favor of building more nuclear weapons.

In an op-ed entitled “The U.S. Needs More Nukes,” Stephens laid out his case against arms control: “the bad guys cheat, the good guys don’t,” and all the while, the US nuclear arsenal is becoming “increasingly decrepit.”

It’s a simple narrative; it’s also false. In fact, Stephens’ article is largely littered with bad analogies, flawed assumptions, and straight-up incorrect facts about the nature of nuclear weapons and arms control.

As examples of arms control agreements where the “bad guys cheat” and the “good guys don’t,” Stephens cites the Anti-Ballistic Missile Treaty (from which the United States withdrew in 2002), the Iran Deal (which was working until the United States withdrew last year), and the Treaty of Versailles (which famously isn’t an arms control agreement), among others. None of these involved significant cheating on the part of the “bad guys,” unless you count the Trump administration’s violation of the Iran Deal in 2018.

Stephens also cites the Intermediate-Range Nuclear Forces Treaty as a prime example of an arms control agreement gone wrong. Yes, it appears that Russia likely violated the Intermediate-Range Nuclear Forces Treaty by developing and deploying a banned ground-launched cruise missile; however, as we’ve written previously, Trump’s decision to pull out of the treaty makes the United States needlessly complicit in its demise and frees Russia from both the responsibility and pressure to return to compliance. Contrary to Stephens’ thesis, when someone breaks the law, you shouldn’t throw away the law.

And contrary to the title of Stephens’ piece, the United States doesn’t need more nukes. As we explain in our latest US Nuclear Notebook, the Trump administration wants to develop two new ones––a low-yield warhead and a sea-launched cruise missile––both of which are dangerous, and neither of which are necessary. Aside from lowering the threshold for nuclear use, the “low-yield” aspect of the low-yield warhead is a misnomer; it’s roughly one-third the yield of the Hiroshima bomb that killed 100,000 people. And the new sea-launched cruise missile is a concept brought back from the dead: the United States had one until 2013, when the Obama administration retired it because it was pointless, wasteful, and politically controversial.

In addition to his well-established denialism of issues like systemic hunger, rape culture, and climate change, Stephens is known for his hawkish––and often inaccurate––takes on nuclear issues. In 2013, he claimed that the Iran Deal was worse than Chamberlain’s appeasement of Hitler in 1938. In 2017, he argued in favor of regime change in North Korea. Later that year, he derisively referred to ICAN––the group that won the Nobel Peace Prize for its work to ban nuclear weapons––as “another tediously bleating ‘No Nukes’ outfit.” In June, he wrote that “If Iran won’t change its behavior, we should sink its navy.” Remember, this is coming from a guy who awarded Iraq War architect Paul Wolfowitz “Man of the Year” in 2003 (The runners-up? Donald Rumsfeld, Dick Cheney, Tony Blair, and George W. Bush).

Furthermore, in last week’s piece, he erroneously stated that Iran repeatedly violated the Joint Comprehensive Plan of Action, a claim which the International Atomic Energy Agency—the international organization charged with monitoring Iran’s compliance––has continuously rebutted. Noticeably, Stephens linked to Mark Fitzpatrick’s work to back up his claim, but when Mark tweeted out that his article didn’t say anything of the sort, the link was changed. It now references David Albright of the Institute for Science and International Security, who is known for his hawkish views on Iran.

Stephens’ columns are clearly emphasizing ideology over accuracy. And publishing a pro-nukes article on the anniversary of the Nagasaki bombing––without acknowledging the human cost of nuclear weapons, or even the anniversary itself––demonstrates that he is clearly not guided by empathy.

But perhaps most evidently, Stephens’ piece is driven by fear. And understandably so: we’re currently locked into an ever-increasing nuclear arms race with no signs of it slowing down. If you’re not afraid, you’re probably not paying attention. However, crying “more nukes” without articulating any kind of strategic vision isn’t going to get us out of this mess. 

In reality, the best way to get out of an arms race is by refusing to play. The United States shouldn’t base the size of its nuclear arsenal in response to how other countries are tweaking theirs––this only makes sense if you believe that nuclear weapons are for fighting wars. But to quote Reagan’s old adage, “A nuclear war cannot be won and must never be fought.” Instead, as explained in Global Zero’s Alternative Nuclear Posture Review, the United States should move towards a “deterrence-only” nuclear posture, which would allow for sizable cuts to the US nuclear arsenal without changing the strategic balance.

Very simply, we need to start enacting ambitious solutions that are equal to the problems that we face. Not just reflexively demanding more nukes.

MacArthur Foundation, the New Land Foundation, the Ploughshares Fund, and the Prospect Hill Foundation. The statements made and views expressed are solely the responsibility of the authors.

Six months after both the United States and Russia announced suspensions of their respective obligations under the Intermediate-Range Nuclear Forces Treaty (INF), the treaty officially died today.

The Federation of American Scientists strongly condemns the irresponsible acts by the Russian and US administrations that have resulted in the demise of this historic and important agreement.

In a they-did-it statement on the State Department’s web site, Secretary of State Michael Pompeo repeated the accusation that Russia has violated the treaty by testing and deploying a ground-launched cruise missile with a range prohibited by the treaty. “The United States will not remain party [sic] to a treaty that is deliberately violated by Russia,” he said.

By withdrawing from the INF, the Trump administration has surrendered legal and political pressure on Russia to return to compliance. Instead of diplomacy, the administration appears intent on ramping up military pressure by developing its own INF missiles.

Signed in 1987, the INF Treaty dramatically helped reduce nuclear threats and stabilize the arms race for thirty-two years, by banning and eliminating all US and Russian ground-launched missiles with ranges between 500 and 5,500 kilometers––a grand total of 2,692 missiles. And it would have continued to have a moderating effect on US-Russia nuclear tensions indefinitely, if not for the recklessness of both the Putin and Trump administrations.

The United States first publicly accused Russia of violating the treaty in its July 2014 Treaty Compliance Report, stating that Russia had broken its obligation “not to possess, produce, or flight-test a ground-launched cruise missile (GLCM) with a range capability of 500 km to 5,500 km, or to possess or produce launchers of such missiles.” Russia initially denied the US claims, repeating for years that no such missile existed. However, once the United States publicly named the missile as the 9M729––or SSC-8, as NATO calls it––Russia acknowledged its existence but stated that the missile “fully complies with the treaty’s requirements.” Since then, the United States claimed that Russia had flight-tested the 9M729 from fixed and mobile launchers to deceive, and has deployed nearly a hundred missiles across four battalions.

We assess that involves 16 launchers with 64 missiles (plus spares), likely collocated with Iskander SRBM units at Elanskiy, Kapustin Yar (possibly moved to a permanent base by now), Mozdok, and Shuya. It is possible, but unknown, if more battalions have been deployed.

It is possible that Russia made the decision to violate the INF Treaty as early as 2007, when its UN proposal to multilateralize the treaty failed. Although it’s likely that the groundwork was laid even further back. According to Putin, a new arms race truly began in 2002 when the Bush administration withdrew from the Anti-Ballistic Missile Treaty––understood by Putin to be the cornerstone of the US-Russia arms control regime.

For its part, Russia has responded to US accusations with claims that the United States is the true violator of the treaty, stating that US missile defense launchers based in Europe could be repurposed to launch INF-prohibited missiles, among other violations. In a detailed report, the Congressional Research Service has refuted all three accusations.

Regardless of who violated the INF, the Trump administration’s decision to kill the treaty is the wrong move. As we wrote in the Bulletin of the Atomic Scientists when Trump first announced his intention to quit the treaty, withdrawal establishes a false moral equivalency between the United States, who probably isn’t violating the treaty, and Russia, who probably is. It also puts the United States in conflict with its own key policy documents like the Nuclear Posture Review and public statements made last year, which emphasized bringing Russia back into compliance through diplomatic, economic, and military measures.

The bottom line is this: when someone breaks the law, you shouldn’t throw away the law. By doing so, you remove any chance to hold the violator accountable for their actions. If the ultimate goal is to coax or coerce Russia back into compliance with the treaty, then killing the treaty itself obviously won’t achieve that. Instead, it legally frees Russia to deploy even more INF missiles.

The decision to withdraw wasn’t based on long-term strategic thinking but appears to have been based on ideology. It was apparently the product of National Security Advisor John Bolton––a hawkish “serial arms control killer”––having the President’s ear. Defense hawks chimed in with warnings about Chinese INF-range missiles being outside the treaty (which they have always been) and recommendations about deploying new US INF missiles in the Pacific.

Now, we find ourselves on the brink of an era without nuclear arms control whatsoever. With the demise of the INF, the only remaining treaty – the New START treaty – is in jeopardy, a vital treaty that caps the number of strategic nuclear weapons the United States and Russia can deploy and provides important verification and data exchanges. Although it could easily be extended past its February 2021 expiry date with the stroke of a pen, John Bolton maddeningly says that it’s “unlikely.” And Russian officials too have begun raising issues about the extension. Allowing New START to expire would do away with the last vestiges of US-Russia nuclear restraint, and open the world up to a new open-ended nuclear arms race.

Congress must do whatever it can to convince President Trump to extend the New START treaty.

Amidst a deepening rift between the United States and Russia about the role of non-strategic nuclear weapons, Russia has begun to upgrade an Air Force nuclear weapons storage site near Tver, some 90 miles (145 kilometers) northeast of Moscow.

Satellite photos show clearing of trees within the site as well as the construction of a new security fence and guard post. The upgrade, which started late-2017 and was completed late last year, was followed by the arrival of what appears to be weapons transport and service trucks earlier this year (see image below).

The Tver site includes two nuclear weapons bunkers as well as service and security buildings. The new security fence and gate added within the site separates the bunker area from the service area. The site is near the Migalovo Air Base, which is not thought to be housing nuclear strike aircraft but might serve a nuclear weapons transport function. If so, it could potentially be responsible for the distribution of nuclear warheads to tactical air bases in north-western Russia in a crisis.

It is impossible to determine from the satellite images if the Tver site stores nuclear weapons at this time, but it is clearly active with considerable personnel and activities indicating weapons might be present. Alternatively, Tver could serve as an Air Force storage site in a crisis. Tver is one of several dozen nuclear weapons storage sites operated by the Russian ministry of defense and military services (see here and here.

There are also important upgrades underway at the Mozhaysk-10 storage site about 70 miles (114 kilometers) west of Moscow, including addition of new support facilities as well clearing of a previously tree-covered weapons storage igloo. Mozhaysk-10 is one of a dozen national-level nuclear weapons storage site and includes six underground igloos and appears to be expanding (see below). Mozhaysk-10 might be used to store both strategic and tactical nuclear weapons.

The upgrades at the Tver and Mozhaysk-10 sites follow an ongoing upgrade to a nuclear weapons storage site in Kaliningrad that began in 2016 and appears intended to support nuclear-capable forces in the isolated enclave.

Russia is estimated to possess approximately 6,500 nuclear warheads, of which an estimated 4,330 are thought to be available for use by the military. We estimate that Russia has about 1,830 nuclear warheads assigned to non-strategic forces; the Pentagon says the number is “up to 2,000” warheads. The US Defense Intelligence Agency (DIA) recently said it expects to see “a significant projected increase in the number of Russia’s non-strategic nuclear weapons” over the next decade, although some past DIA growth projections have turned out to exaggerated.

In response, the United States has begun to increase the upgrade of its non-strategic nuclear weapons beyond the already-planned B61-12 guided gravity bomb for stealthy F-35 fighter-bombers. New weapons with “tactical” missions include the W76-2 low-yield warhead on the Trident II D5LE SLBM and a new nuclear sea-launched cruise missile. And NATO has been upgrading US nuclear weapons storage sites in Europe.

Russia and the United States refuse to disclose how many tactical nuclear weapons they have or where they are stored, and none of these weapons are limited by arms control agreements.

We will further describe these developments, and much more, in our upcoming Nuclear Notebook on tactical nuclear weapons scheduled for publication in the Bulletin of the Atomic Scientists in September 2019.

During a Hudson Institute conference on Russian and Chinese nuclear modernizations, director of the Defense Intelligence Agency (DIA) Lt. Gen. Robert Ashley said in prepared remarks: “Over the next decade, China is likely to at least double the size of its nuclear stockpile…”

This projection is new and significantly above recent public statements by US government agencies. But how reliable is it and how have US agencies performed in the past?

The public record is limited because estimates are normally classified and agencies and officials are reluctant to say too much. But a few examples exist from declassified documents and public statements. These estimates vary considerably – some seemed downright crazy.

But before analyzing DIA’s projection for the future, let’s examine what the estimated Chinese nuclear stockpile looks like today.

Current Chinese Stockpile Estimate

While warning the Chinese stockpile will “at least double” over the next decade, Lt. Gen. Ashley’s prepared remarks did not say what it is today. But in the follow-up Q/A session, he added: “We estimate…the number of warheads the Chinese have is in the low couple of hundreds.

That estimate is close to statements made by DOD and STRATCOM nearly a decade ago. In our forthcoming Nuclear Notebook on Chinese nuclear forces (scheduled for publication in July 2019), we estimate the Chinese stockpile now includes approximately 290 warheads and is likely to surpass the size of the French nuclear stockpile (~300 warheads) in the near future.

Earlier Chinese Stockpile Estimates

Earlier projections made by US agencies of China’s nuclear stockpile have varied considerably. DIA’s estimates have consistently been higher – even extraordinarily so – than that of other agencies (see graph below). The wide range reflects an enormous uncertainty and lack of solid intelligence, which makes it even more curious why DIA would make them. This record obviously raises questions about DIA’s latest projection.

In April 1980s, for example, DIA published a Defense Estimate Brief with the title: Nuclear Weapons Systems in China. The brief, which was prepared by the China/Far East Division of the Directorate for Estimates and approved by DIA’s deputy assistant director for estimates, projected an astounding growth for China’s nuclear arsenal that included everything from ICBMs, MRBMs, SRBMs, bombs, landmines, and air-to-surface missiles. The brief concluded a curious double estimate of 150-160 warheads in the text and 360 warheads in a table and projected an increase from 596 warheads in 1989 to as many as 818 by 1994. The brief was partially redacted for many years but it has since been possible to reconstruct in its entirety because of inconsistencies in the processing of different FOIA requests.

In the 1990s, CIA published three estimates, all significantly lower than the DIA projection from 1984. But DIA apparently was reworking its methodology because in 1999 it published A Primer On The Future Threat that was lower than the CIA estimate but projected an increase of the Chinese stockpile from 140-157 warheads to 358-464 warheads in 2020. The Primer predicted that deployment of US missile defenses would cause China to significantly increase its ICBM force, a prediction that has come through to some extent and is now ironically used by DIA and others to warn of a growing Chinese nuclear threat against the United States.

Following an intense debate in 2010 about Senate approval of the New START treaty, then-principle deputy undersecretary of defense for policy James Miller told Congress in 2011: “China is estimated to have only a few hundred nuclear weapons….”

And when false rumors flared up in 2012 that China had hundreds – even thousands – of warheads more than commonly assumed, STRATCOM commander Gen Kehler rebutted the speculations saying: “I do not believe that China has hundreds or thousands more nuclear weapons than what the intelligence community has been saying,” which is “that the Chinese arsenal is in the range of several hundred” nuclear warheads.

Since then, China has started to deploy the modified silo-based DF-5B ICBM that is equipped with multiple warheads (MIRV) – part of the response to the US missile defenses that DIA predicted in 1999, and deployed a significant number of dual-capable DF-26 IRBMs. Even so, Ashley’s most recent statement roughly matches the estimates made by Miller and Kehler nearly a decade ago, when he says: “We estimate…the number of warheads the Chinese have is in the low couple of hundreds.”

How Could The Chinese Stockpile More Than Double?

Although Ashley predicted a significant expansion of the Chinese stockpile, he did not explain the assumptions that go into that assessment. What would China have to do in order to more than double its stockpile over the next decade?

There are several potential options. China could field a significant number of additional launchers, or deploy significantly more MIRVs on some of its missiles, or – if the MIRV increase is less dramatic – a combination of more launchers and more MIRV. It seems likely to be the latter option.

Additional MIRVing seems to be an important factor. China is developing the road-mobile DF-41 ICBM that is said to be capable of carrying MIRV. It is also developing a third modification of the silo-based DF-5 (DF-5C) that may have additional MIRV capability compared with the current DF-5B. Finally, the next-generational JL-3 SLBM could potentially have MIRV capability, although I have yet to see solid sources saying so. There are many rumors about up to 10 MIRV per DF-41 (even unreliable rumors about MIRV on shorter-range systems), but if China’s decision to MIRV is a response to US missile defenses (which DIA and DOD have stated for years), then it seems more likely that the number of warheads on each missile is low and the extra spaces used for decoys.

China is also expanding its SSBN fleet, which could potentially double in size over the next decade if the production of the next-generation Type-096 gets underway in the early-2020s. And China reportedly has reassigned a nuclear mission to its bombers, is developing a new nuclear-capable bomber, and an air-launched ballistic missile that might have a nuclear option. Assuming a few bomber squadrons would a nuclear capability by the late-2020s, that could help explain DIA’s projection as well. Altogether, that adds up to a hypothetical arsenal that could potentially look like this in order to “at least double” the size of the stockpile:

Conclusions

Whether DIA’s projection comes through of a Chinese stockpile “at least double” the size of the current inventory remains to be seen. Given DIA’s record of worst-case predictions, there are good reasons to be skeptical. It would, at a minimum, be good to hear what the coordinated Intelligence Community assessment is. Does the Director of National Intelligence agree with this projection?

That said, the Chinese leadership has obviously decided that its “minimum deterrent” requires more weapons. To that end, the debate over how much is enough, what the Chinese intentions are, and what the US response should be, are important reminders that the Chinese leadership needs to be more transparent about what its modernization plans are. Lack of basic information from China fuels worst-case assumptions in the United States that can (and will) be used to justify defense programs that increase the threat against China. The recommendation by the Nuclear Posture Review to develop a new nuclear-armed sea-launched cruise missile is but one example. Both sides have an interest in limiting this action-reaction cycle.

Even if DIA’s projection of a more than doubling of the Chinse stockpile were to happen, that would still not bring the inventory anywhere near the size of the US or Russian stockpiles. They are currently estimated at 4,330 and 3,800 warheads, respectively – even more, if counting retired, but still largely intact, warheads awaiting dismantlement.

But despite the much smaller Chinese arsenal, a significant expansion of the stockpile would likely make US and Russia even more reluctant to reduce their arsenals – a reduction the Chinese government insists is necessary first before it will join a future nuclear arms limitation agreement. So while China’s motivation for increasing its arsenal may be to reduce the vulnerability of its deterrent, it may in fact also cause the United States and Russian to retain larger arsenals than otherwise and even increase their capabilities to threaten China.

Whether DIA’s projection pans out or not, it is an important reminder of the increasingly dynamic nuclear competition that is in full swing between the large nuclear weapons states. The pace and scope of that competition are intensifying in ways that will diminish security and increase risks for all sides. Strengthening deterrence is not always beneficial and even smaller arsenals can have significant effects.

The Pentagon has decided not to disclose the current number of nuclear weapons in the Defense Department’s nuclear weapons stockpile. The decision, which came as a denial of a request from FAS’s Steven Aftergood for declassification of the 2018 nuclear weapons stockpile number, reverses the U.S. practice from the past nine years and represents an unnecessary and counterproductive reversal of nuclear policy.

The United States in 2010 for the first time declassified the entire history of its nuclear weapons stockpile size, a decision that has since been used by officials to support U.S. non-proliferation policy by demonstrating U.S. adherence to the nuclear Non-Proliferation Treaty (NPT), providing transparency about U.S. nuclear weapons policy, counter false rumors about secretly building up its nuclear arsenal, and to encourage other nuclear-armed states to be more transparent about their arsenals.

Importantly, the U.S. also disclosed the number of warheads dismantled each year back to 1994. This disclosure helped document that the United States was not hiding retired weapons but actually dismantling them. In 2014, the United States even declassified the total inventory of retired warheads still awaiting dismantlement at that time: 2,500.

The 2010 release built on previous disclosures, most importantly the Department of Energy’s declassification decisions in 1996, which included – among other issues – a table of nuclear weapons stockpile data with information about stockpile numbers, megatonnage, builds, retirements, and disassemblies between 1945 and 1994. Unfortunately, the web site is poorly maintained and the original page headlined “Declassification of Certain Characteristics of the United States Nuclear Weapon Stockpile” no longer has tables, another page is corrupted, but the raw data is still available here. Clearly, DOE should fix the site.

The decision in 2010 to disclose the size of the stockpile and the dismantlement numbers did not mean the numbers would necessarily be updated each subsequent year. Each year was a separate declassification decision that was announced on the DOD Open Government web site. The most recent decision from 2018 in response to a request from FAS showed the stockpile number as of September 2017: 3,822 stockpiled warheads and 354 dismantled warheads.

The 2017 number was extra good news because it showed the Trump administration, despite bombastic rhetoric from the president, had continued to reduce the size of the stockpile (see my analysis from 2018).

Since 2010, Britain and France have both followed the U.S. example by providing additional information about the size of their arsenals, although they have yet to disclose the entire history of their warhead inventories. Russia, China, India, Pakistan, Israel, and North Korea have not yet provided information about the size or history of their arsenals.

FAS’ Role In Providing Nuclear Transparency

The Federation of American Scientists (FAS) has been tracking nuclear arsenals for many years, previously in collaboration with the Natural Resources Defense Council (NRDC). The 5,113-warhead stockpile number declassified by the Obama administration in 2010 was only 13 warheads off the FAS/NRDC estimate at the time.

We provide these estimates on our web site, on our Strategic Security Blog, and in publications such as the bi-monthly Nuclear Notebook published in the Bulletin of the Atomic Scientists and the annual nuclear forces chapter in the SIPRI Yearbook. The work is used extensively by journalists, NGOs, scholars, parliamentarians, and government officials.

With the Pentagon decision to close the books on the stockpile, and the rampant nuclear modernization underway worldwide, the role of FAS and others in documenting the status of nuclear forces will be even more important.

Conclusions and Recommendations

The Pentagon’s decision not to disclose the 2018 nuclear weapons stockpiled and dismantled warhead numbers is unnecessary and counterproductive.

The United States or its allies are not suffering or at a disadvantage because the nuclear stockpile numbers are in the public. Indeed, there seems to be no rational national security factor that justifies the decision to reinstate nuclear stockpile secrecy.

The decision walks back nearly a decade of U.S. nuclear weapons transparency policy – in fact, longer if including stockpile transparency initiatives in the late-1990s – and places the United States is the same box as over-secretive nuclear-armed states, several of which are U.S. adversaries.

The decision also puts the United States in an even more disadvantageous position for next year’s nuclear Non-Proliferation Treaty (NPT) review conference where the administration will be unable to report progress on meeting its Article VI obligations. Instead, this decision, as well as decisions to withdraw from the INF treaty, start producing new nuclear weapons, and the absence of nuclear arms control negotiations, needlessly open up the United States to criticism from other Parties to the NPT – a treaty the United States needs to protect and strengthen to curtail nuclear proliferation.

The decision also puts U.S. allies like Britain and France in the awkward position of having to reconsider their nuclear transparency policies as well or be seen to be out of sync with their largest military ally at a time of increased East-West hostilities.

With this decision, the Trump administration surrenders any pressure on other nuclear-armed states to be more transparent about the size of their nuclear weapon stockpiles. This is curious since the Trump administration had repeatedly complained about secrecy in the Russian and Chinese arsenals. Instead, it now appears to endorse their secrecy.

The decision will undoubtedly fuel suspicion and worst-case mindsets in adversarial countries. Russia will now likely argue that not only has the United States obscured conversion of nuclear launchers under the New START treaty, it has now decided also to keep secret the number of nuclear warheads it has available for them.

Finally, the decision also makes it harder to envision achieving new arms control agreements with Russia and China to curtail their nuclear arsenals. After all, if the United States is not willing to maintain transparency of its warhead inventory, why should they disclose theirs?

It is yet unclear why the decision not to disclose the 2018 stockpile number was made. There are several possibilities:

• Is it because the chaos and incompetence in the Trump administration have enabled hardliners and secrecy zealots to reverse a policy they disagreed with anyway?
• Is it a result of the Nuclear Posture Review’s embrace of Great Power Competition with Cold War-like instincts to increase reliance on nuclear weapons, kill arms control treaties, increase secrecy, and scuttle policies that some say appease adversaries?
• Is it because of a Trump administration mindset opposing anything created by president Obama?
• Or is it because the United States has secretly begun to increase the size of its nuclear stockpile? (I don’t think so; the stockpile appears to have continued to decrease to now at or just below 3,800 warheads.)

The answer may be as simple as “because it can” with no opposition from the White House. Whatever the reason, the decision to reinstate stockpile secrecy caps a startling and rapid transformation of U.S. nuclear policy. Within just a little over two years, the United States under the chaotic and disastrous policies of the Trump administration has gone from promoting nuclear transparency, arms control, and nuclear constraint to increasing nuclear secrecy, abandoning arms control agreements, producing new nuclear weapons, and increasing reliance on such weapons in the name of Great Power Competition.

This is a historic policy reversal by any standard and one that demands the utmost effort on the part of Congress and the 2020 presidential election candidates to prevent the United States from essentially going nuclear rogue but return it to a more constructive nuclear weapons policy.
