An important new treaty reduces the limit for deployed strategic warheads but not the number.

By Hans M. Kristensen

The White House has announced that it has reached agreement with Russia on the New START Treaty. Although some of the documents still have to be finished, a White House fact sheet describes that the treaty limits the number of warheads on deployed ballistic missiles and long-range bombers on both sides to 1,550 and the number of missiles and bombers capable of launching those warheads to no more than 700.

The long-awaited treaty is a vital symbol of progress in U.S.-Russian relations and an important additional step in the process of reducing and eventually perhaps even achieving the elimination nuclear weapons. It represents a significant arms control milestone that both countries should ratify as soon as possible so they can negotiate deeper cuts.

Yet while the treaty reduces the legal limit for deployed strategic warheads, it doesn’t actually reduce the number of warheads.  Indeed, the treaty does not require destruction of a single nuclear warhead and actually permits the United States and Russia to deploy almost the same number of strategic warheads that were permitted by the 2002 Moscow Treaty.

The major provisions of the New START Treaty are:

• 1,550 deployed strategic warheads: Warheads on deployed ICBMs and deployed SLBMs count toward this limit and each deployed heavy bomber equipped for nuclear armaments counts as one warhead toward this limit.
• A limit of 700 deployed ICBMs, deployed SLBMs, and deployed heavy bombers equipped for nuclear armaments.
• A limit of 100 non-deployed ICBM launchers (silos), SLBM launchers (tubes), and heavy bombers equipped for nuclear armaments.

These limits don’t have to be met until 2017, and will remain in effect for three years until the treaty expires in 2020 (assuming ratification occurs this year). Once it is ratified, the 2002 Moscow Treaty (SORT) falls away.

Verification Extended

The most important part of the new treaty is that it extends a verification regime at least a decade into the future. The inspections and other verification procedures in this Treaty will be simpler and less costly to implement than the old START treaty, according to the White House.

This includes on-site inspections. Each side gets a total of 18 per year, ten of which are actual warhead counts of deployed missiles and the remaining eight being “Type 2” inspections of storage and dismantlement facilities.

Exchange of missile test telemetry data has been limited partly because it is not as necessary for verification as previously; there are other means for collecting this information. Even so, the treaty includes exchange of telemetry data for five test flights each year.

The Fine Print: Limits Versus Reductions

The White House fact sheet states that the new limit of 1,550 deployed strategic warheads is 74% lower than the 6,000 warhead limit of the 1991 START Treaty, and 30% lower than the 2,200 deployed strategic warhead limit of the 2002 Moscow Treaty.

That is correct, but the limit allowed by the treaty is not the actual number of warheads that can be deployed. The reason for this paradox is a new counting rule that attributes one weapon to each bomber rather than the actual number of weapons assigned to them. This “fake” counting rule frees up a large pool of warhead spaces under the treaty limit that enable each country to deploy many more warheads than would otherwise be the case. And because there are no sub-limits for how warheads can be distributed on each of the three legs in the Triad, the “saved warheads” from the “fake” bomber count can be used to deploy more warheads on fast ballistic missiles than otherwise.

Under the New START Treaty That’s One Nuclear Bomb!

The New START Treaty counts each nuclear bomber as one nuclear weapon even though U.S. and Russian bombers are equipped to carry up to 6-20 weapons each. This display at Barksdale Air Base shows a B-52 with six Air Launched Cruise Missiles, four B-61-7 bombs, two B83 bombs, six Advanced Cruise Missiles (now retired), and eight Air Launched Cruise Missiles. Russian bombers can carry up to 16 nuclear weapons.

.
The Moscow Treaty attributed real weapons numbers to bombers. The United States defined that weapons were counted as “operationally deployed” if they were “loaded on heavy bombers or stored in weapons storage areas of heavy bomber bases.” As a result, large numbers of bombs and cruise missile have been removed from U.S. bomber bases to central storage sites over the past five years, leaving only those bomber weapons that should be counted against the 2,200-warhead Moscow Treaty limit.

Since the new treaty attributes only one warhead to each bomber, it no longer matters if the weapons are on the bomber bases or not; it’s the bomber that counts not the weapons. As a result, a base with 22 nuclear tasked B-52 bombers will only count as 22 weapons even though there may be hundreds of weapons on the base.

According to U.S. officials, the United States wanted the New START Treaty to count real warhead numbers for the bombers but Russia refused to prevent on-site inspections of weapons storage bunkers at bomber bases. As a result, the 36 bombers at the Engels base near Saratov will count as only 36 weapons even though there may be hundreds of weapons at the base.

If the New START Treaty counting rule is used on today’s postures, then the United States currently only deploys some 1,650 strategic warheads, not the actual 2,100 warheads; Russia would be counted as deploying about 1,740 warheads instead of its actual 2,600 warheads. In other words, the counting rule would “hide” approximately 450 and 860 warheads, respectively, or 1,310 warheads. That’s more warheads that Britain, China, France, India, Israel, and Pakistan possess combined!

Dodging The Issue

Update March 30: Ellen Tauscher, the U.S. Under Secretary for Arms Control and International Security, was asked at a press briefing to explain the rationale behind the “fake” bomber warhead counting rule, but dodged the issue: “Well, I think what we want to do right now is talk about why this is an important treaty….” Increased transparency of bomber weapons would greatly improve the importance of the new treaty; the U.S. and Russia have more bomber warheads than the total nuclear weapon inventory of all other nuclear weapon states combined. If they have to use an arbitrary bomber warhead number because it’s too hard to verify, why chose 1? Why not 10 (as START I did) or 12, the medium loading capacity of U.S. and Russian bombers?

The paradox is that with the “fake” bomber counting rule the United States and Russia could, if they chose to do so, deploy more strategic warheads under the New START Treaty by 2017 than would have been allowed by the Moscow Treaty by 2012.

Force Structure Changes

How the new treaty and the “fake” counting rule will affect U.S. and Russian nuclear force structures depends on decisions that will be made in the near future. In the negotiations both Russia and the United States resisted significant changes to their nuclear forces structures.

Russia resisted restrictions on warheads numbers to keep some degree of parity with the United States. It achieved this by the “fake” bomber weapon count and the delivery platform limit that is higher than what Russia deploys today. Under the New START Treaty, Russia can deploy more strategic warheads on its ballistic missiles than it would have been able to under the Moscow Treaty, although it probably won’t do so due to retirement of older systems. It can continue all its current and planned force structure modernizations.

The United States resisted restrictions on its upload capability, which it achieved by the high limit on delivery platforms. The “fake” bomber count enables more weapons to be deployed on ballistic missiles and more weapons to be retained at bomber bases than would have been possible under the Moscow Treaty. The SLBM-heavy (in terms of warheads) U.S. posture “eats up” a large portion of the 1,550 warhead limit, so the U.S. Nuclear Posture Review soon to be completed will probably reduce the warhead loading on each SLBM, and possible cut about 100 missiles from the ICBM force. The incentive to limit bomber weapons further is gone with the new treaty, although it could happen for other reasons. All current and planned modernizations can continue.

Although Russia has thousands of extra weapons in storage, all its deployed missiles are thought to be loaded to near capacity. As a result, under the New START Treaty, Russia will have little upload capacity. The United States, on the other hand, has only a portion of its available warheads deployed and lots of empty spaces on its missiles. The large pool of reserve warheads available for potential upload creates a significant disparity in the two postures so it is likely that the Nuclear Posture Review will reduce the size of the reserve.

Estimated U.S. and Russian Strategic Warheads, 2017

Although the New START Treaty reduces the limit for deployed strategic warheads, a “fake” bomber weapon counting rule enables both countries to continue to deploy as many weapons as under the Moscow Treaty. A high limit for delivery vehicles protects a significant U.S. upload capacity, whereas Russia will have essentially none. Future force structure decisions might affect the exact numbers but this graph illustrates the paradox.

.
Conclusions and Recommendations

The New START Treaty is an important achievement in restarting relations with Russia after the abysmal decline during the Bush administration. And extending and updating the important verification regime creates a foundation for transparency and confidence building.

The treaty will also, if ratified quickly and followed up by additional reductions, assist in strengthening the international nonproliferation regime and efforts to prevent other countries from developing nuclear weapons.

The United States and Russia must be careful not to “oversell” the treaty as creating significant reductions in nuclear arsenals and strategic delivery systems. Although the treaty reduces the limit, the achievement is undercut by a new counting rule that enables both countries to deploy as many strategic warheads as under the Moscow Treaty.

Indeed, the New START Treaty is not so much a nuclear reductions treaty as it is a verification and confidence building treaty.  It is a ballistic missile focused treaty that essentially removes strategic bombers from arms control.

The good news is that a modest treaty will hopefully be easier to ratify.

Because the treaty protects current force structures rather than reducing them, it will inevitably draw increased attention to the large inventories of non-deployed weapons that both countries retain and can continue to retain under the new treaty. Whereas the United States force structure is large enough to permit uploading of significant numbers of reserve warheads, the Russian force is too small to provide a substantial upload capacity. Even with a significant production of new missiles, it is likely that Russia’s entire Triad will drop to around 400 delivery vehicles by 2017 – fewer than the United States has today in its ICBM leg alone. That growing disparity makes it imperative that the forthcoming U.S. Nuclear Posture Review reduces the number of delivery vehicles and reserve warheads.

To that end it is amazing to hear some people complaining that the U.S. deterrent is dilapidating and that the United States doesn’t gain anything from the New START Treaty. In the words of one senior White House official, the United States came away as a “clean winner.”

Because the treaty does not force significantly deeper reductions in the number of nuclear weapons compared with the Moscow Treaty, it is important that presidents Obama and Medvedev at the signing ceremony in Prague on 8 April commit to seeking rapid ratification and achieving additional and more drastic nuclear reductions.

The latest IAEA report on Iran has been widely touted as containing new evidence of Iranian weapons work and as a sign of the Agency’s new hard-line attitude toward the Islamic Republic under its new Director General Yukiya Amano. We believe the document has been seriously misrepresented in the media and elsewhere, which could have dangerous consequences.  We made this argument in a recent op-ed in the Bulletin of the Atomic Scientists.

We should all bother to do a little reading and get our facts straight. If there was a case for new crippling sanctions or for bombing Iran before, the report adds nothing new.    The February report contains no new evidence of Iranian weapons work that was not already in the public domain. There is no independent IAEA assessment that Iran currently has or has ever had a nuclear weapons program. This is also hardly the first time that the Agency has addressed outstanding questions pertaining to the possible military dimension of Iran’s nuclear program and has asked for Iran to respond.

Very limited space in our brief Bulletin op-ed did not allow us to address the issue of Amano’s allegedly new tougher tone. The February document, being Amano’s first, has been subject to an exegesis to discern potential attitudes from the director and has been described by Western media as blunt and even confrontational. Inside Iran, the issue of tone has been viewed by some as a “direct result of a change in leadership, and not the outcome of an unbiased evaluation.” (more…)

The Air Force is considering a replacement for the nuclear air-launched cruise missile. Will the NPR agree or adhere to Barack Obama’s no-new-nuclear-weapons pledge?

.
By Hans M. Kristensen [updated March 18, 2010]

One of the important tests of Obama Administration’s nuclear nonproliferation policy will be whether the long-delayed Nuclear Posture Review will approve new nuclear weapons.

During his election campaign, Barack Obama promised not to build new nuclear weapons, a pledge that recently has been reiterated by the administration.

Yet the Air Force’s budget request for 2011 includes several projects that, if approved, would contradict the pledge.

The “No New” Pledge

During the presidential election campaign, Barack Obama pledge to “stop the development of new nuclear weapons” if elected president. The pledged lived on for the first few months after the election on the Obama administration’s White House foreign policy web page, but disappeared when the page was reorganized at the time of the Prague speech in April 2009.

Since the, the president has, to my knowledge, not repeated the pledge. But Under Secretary of State Ellen Tauscher echoed the election pledge last month when she explained that the Pentagon says it does “not need new nuclear weapons capabilities. They just want to be confident in what we have,” she said and declared: “We are not in the business of seeking new nuclear capabilities. They are not needed to preserve a strong, credible deterrent.”

New Nuclear Weapons

Yet “new” seems to be an elusive term. Even though Tauscher promised that the “RRW is dead and is not coming back,” the Air Force nuclear weapons support program includes “Reliable Replacement Warhead (RRW) Studies & Analysis” in both 2010 and 2011. Perhaps she meant RRW as it was known rather than ruling out future replacement warheads. [Update March 18, 2010: The US Air Force now says the reference to RRW studies and analysis is an error and that the item mistakenly was left in the budget request from the previous year]

More RRW Studies?

Despite a promise that the “RRW is dead and is not coming back,” the Air Force budget request includes RRW studies and analysis in both 2010 and 2011. Click for larger version.

.
Another apparent contradictions with the administration’s no new nuclear weapons pledge is a new nuclear cruise missile to replace the current Air Launched Cruise Missile (ALCM) that expires in 2030. The new weapon is known as the Enhanced Cruise Missile (ECM), and development of nuclear weapons requirements documents are planned for 2010 and 2011, along with a Phase 6.2 Study, also known as a Feasibility Study and Option Down Select study. [Update March 18, 2010: The US Air Force now says the reference to the ECM is an error and that the item mistakenly was left in the budget request from the previous year. But the reference to the LRSO is not an error]

A New Nuclear Cruise Missile?

The Air Force budget request includes what appears to be a replacement for the nuclear Air Launched Cruise Missile. Will the NPR approve? Click for larger version.

.
The Enhanced Cruise Missile appears to be part of a program known as the Follow-On Long Range Stand-Off (LRSO) Vehicle to develop a replacement for the Air Launched Cruise Missile (ALCM).

The plan includes production of the Initial Capabilities Document (ICD) in early 2010, a Material Development Decision (MDD) in September 2010, and an Acquisition Decision in late 2011 or 2012. With that timeline, the NPR will have to make a decision.

New or Modified Warhead

One question is whether the new cruise missile will use a modified version of the existing W80-1 warhead currently deployed on the ALCM for B-52 delivery, or require development of a new warhead.

A W80-1 warhead is mated with an ALCM.

Until 2006, a life extension program (LEP) existed to extend the life of the W80-1. The LEP version was called W80-3. A parallel program to extend the W80-0 warhead would have produced the W80-2. But the Bush administration decided to “defer” the programs in pursuit of the RRW. That effort failed but the W80 LEP is still “archived,” according to the Air Force FY2011 budget request.

The remaining W80-1 warheads are scheduled to receive new neutron generators in 2015-2017, but a refurbishment of the nuclear explosive package is not planned until 2036-2039, according to the NNSA’s FY09 refurbishment planning schedule (no schedule exists yet for FY2010 or FY2011). No life-extension is planned for the W80-0, which will be retired.

Warhead Refurbishment Plan?

The National Nuclear Security Administration’s nuclear warhead refurbishment plan does not include a formal life-extension program for the W80-1 warhead. An expensive program would be added if the NPR approves the Air Force’s cruise missile plan. Chart obtained under FOIA. Click for larger version.

.
A decision to use a modified version of the existing W80-1 in the new cruise missile would involve reviving the $200 million per year W80-3 LEP program.

New or Just “New”

Nuclear weapons modernization programs risk triggering a contentious debate similar to the dispute over the RRW and whether Obama’s no-nuclear-weapons pledge can be trusted.

Does a new “weapon” refer to the warhead on the missile or the delivery vehicle itself or both? And how new must a weapon be to be considered “new” – does it require an entirely new design or can a modified design be considered a “new” weapon?

Government officials have to be crystal clear when they present the results of the NPR to make sure the administration’s nonproliferation policy doesn’t get stuck in the mud of misunderstandings and contradictions about what constitutes a “new” nuclear weapon. A lot is at stake.

One of China’s two new Jin-class SSBNs was photographed with two of its 12 missile tubes open when it visited Xiaopingdao Naval Base in March 2009.

The Jins are being readied to carry the JL-2, a single-warhead regional sea-launched ballistic missile that was most recently test-launched in May 2008. The class may become operational soon and replace the old Xia from 1982.

Xiaopingdao Naval Base, which is where I identified the Jin-class for the first time in 2007, serves as an outfitting and testing facility for new submarines and used to be the homeport of the single Golf-class diesel submarine China used for many years as a test launch platform for its first ballistic missile.

Two or three Jin-class SSBN have been under construction, and it remains to be seen if China will build up to five as projected by U.S. intelligence. China’s nuclear submarines appear to be the noisiest nuclear submarines in the world and will probably be highly vulnerable at sea.

The U.S. Office of Naval Intelligence described in August 2009 that two of China’s SSBNs (probably one Jin and the Xia) were based at the Northern Fleet Base in Jianggezhuang, and the third boat (probably the second Jin) at the Southern Fleet Base on Hainan Island. I identified the Jin at Hainan in February 2008.

The Obama administration’s first version of The Military Power of the People’s Republic of China is expected within the next month or two.

Release of the Nuclear Posture Review (NPR) is delayed once again.  Originally due late last year, in part so it could inform the on-going negotiations on the Strategic Arms Reduction Treaty Follow-on (START-FO), after a couple of delays it was supposed to be released today, 1 March, but last week word got out that it will be coming out yet another 2-4 weeks later.  Some reports are that the delay reflects deep divisions within the administration over the direction of the NPR.  That means that there is really only one person left whose opinion matters and that is the president.

We can only hope that President Obama makes clear that he meant what he said in Prague and elsewhere.  This NPR is crucial.  If it is incremental, if it relegates a world free of nuclear weapons to an inspiring aspiration, then we are stuck with our current nuclear standoff for another generation.  This is the time to decisively shift direction.  But we should not be paralyzed by thinking that the only movement available is a giant leap into the unknown.  We need to move decisively in the right direction, sure, but we can do that in steps.

The current U.S. strategic war plan is directed against six adversaries. Guess who.

By Hans M. Kristensen

While the completion of the Obama administration’s Nuclear Posture Review continues to slide, FAS today published an issue paper on how a decision to reduce the role of nuclear weapons might influence the U.S. strategic war plan.

President Obama pledged in his Prague speech last year that he would “reduce the role of nuclear weapons” to “put an end to Cold War thinking,” and reaffirmed earlier this month that the “Nuclear Posture Review will reduce [the] role….”

How to reduce the role in a way that is seen as significant by the global nonproliferation community, visible to adversaries, and compatible with the president’s other pledge to “maintain a safe, secure and effective arsenal to deter any adversary…as long as these weapons exist” apparently is the subject of a heated debate within the administration.

Click image to download report.

The most persistent rumor is that the review might remove a requirement to plan nuclear strikes against chemical and biological weapons; reduce the mission to the core role of deterring use of other nuclear weapons. I recently described that the Quadrennial Defense Review stated that new regional deterrence architectures and non-nuclear capabilities “make possible a reduced role for nuclear weapons in our national security strategy.”

A reduction of the mission to only deter nuclear use would roll back much of the expansion of nuclear doctrine that happened during the Clinton and Bush administrations. But it would not “put an end to Cold War thinking,” but to post-Cold War thinking.

To put an end to Cold War thinking, the reduced role would have to affect the core of the war plan that is directed against Russia and China.

The issue paper describes how the strategic war plan is structured, how it has evolved, and discusses options for reducing the mission and the war plan itself.

The Quadrennial Deference Review forecasts reduction in regional role of nuclear weapons.

By Hans M. Kristensen

A little-noticed section of the Quadrennial Defense Review recently published by the Pentagon suggests that that the Obama administration’s forthcoming Nuclear Posture Review will reduce the role of nuclear weapons in regional scenarios.

The apparent reduction coincides with a proposal by five NATO allies to withdraw the remaining U.S. tactical nuclear weapons from Europe.

Another casualty appears to be a decision to retire the nuclear-armed Tomahawk sea-launched land-attack cruise missile, despite the efforts of the Congressional Strategic Posture Commission.

New Regional Deterrence Architectures

Earlier this month President Barack Obama told the Global Zero Summit in Paris that the NPR “will reduce [the] role and number of nuclear weapons in our national security strategy.” The reduction in numbers will initially be achieved by the START follow-on treaty soon to be signed with Russia, but where the reduction in the role would occur has been unclear.

Yet the Quadrennial Defense Review (QDR) published earlier this month strongly suggests that the reduction in the role will occur in the regional part of the nuclear posture:

“To reinforce U.S. commitments to our allies and partners, we will consult closely with them on new, tailored, regional deterrence architectures that combine our forward presence, relevant conventional capabilities (including missile defenses), and continued commitment to extend our nuclear deterrent. These regional architectures and new capabilities, as detailed in the Ballistic Missile Defense Review and the forthcoming Nuclear Posture Review, make possible a reduced role for nuclear weapons in our national security strategy.” (emphasis added)

There are two parts (with some overlap) to the regional mission: the role of nuclear weapons against regional adversaries (North Korea, Iran, and Syria); and the role of nuclear weapons deployed in Europe.

Rumors have circulated for long that the administration will remove the requirement to plan nuclear strikes against chemical and biological weapons from the mission; to limit the role to deterring nuclear attacks. Doing so would remove Iran, Syria and others as nuclear targets unless they acquire nuclear weapons. A broader regional change could involve leaving regional deterrence against smaller regional adversaries (including North Korea) to non-nuclear forces and focus the nuclear mission on the large nuclear adversaries (Russia and China).

An immediate consequence of the new architecture appears to be a decision to retire the nuclear Tomahawk sea-launched land-attack cruise missile (TLAM/N). According to a report by Kyodo News (see also report by Daily Yomiuri), Washington has informally told the Japanese government that it intends to retire the weapon. The 2009 Congressional Strategic Posture Commission report had recommended retaining the weapons, but neither the Pentagon nor the Japanese government apparently agreed.

Nuclear Tomahawk To Be Retired

The Obama administration has informally told the Japanese government that the nuclear Tomahawk cruise missile will be retired. The retirement appears to be part of a new regional deterrence architecture that enables a reduction of the role of nuclear weapons.

.
A Nuclear Withdrawal From Europe?

The other part of the regional mission concerns the deployment of nuclear weapons in Europe, where the U.S. Air Force currently deploys 150-200 nuclear bombs at six bases in five NATO countries. Some of the TLAM/Ns also are earmarked for support of NATO, but are stored on land in the United States. The weapons are the last remnant of the Cold War deployment of thousands of tactical nuclear weapons to deter a Soviet attack on Europe. Similar deployments in the Pacific ended two decades ago and pressure has been building for NATO to finally end the Cold War.

Three of the five NATO countries that currently host the U.S. nuclear bombs on their territories are expected to ask for the weapons to be withdrawn, according to a report by AFP.

A spokesperson for the Belgian Prime Minister said that Belgium, German, and the Netherlands, together with Norway and Luxemburg, in the coming weeks will formally propose within NATO that “that nuclear arms on European soil belonging to other NATO member states are removed.”

Presumably, some coordination with Washington has taken place. Otherwise, if the NPR does not recommend a withdrawal from Europe, the five countries’ initiative will from the outset be in conflict with the Obama administration’s nuclear policy, which NATO likely will follow.

The European initiative would help the Obama administration justify a decision to withdraw the weapons from Europe by demonstrating that key NATO allies no longer see a need for the deployment. Extended nuclear deterrence would continue, as the QDR language underscores, but with long-range strategic weapons as it is done in the Pacific.

Other than the forthcoming NPR, the political context for the European initiative is NATO’s ongoing review of its Strategic Concept, scheduled for completion in November.  The Obama administration might not want to preempt that review, so an alternative could be that the NPR concludes that the U.S. sees no need for the continued deployment of nuclear weapons in Europe but leaves it up to NATO’s new Strategic Concept to make the formal decision. In that case, the initiative by the five NATO countries could serve to formally start that process within NATO. (see comments by U.S. NATO Ambassador Ivo Daalder)

Whether that means a complete withdrawal from Europe now, a decision to end the NATO strike portion (a controversial Cold War mission that assigns nuclear weapons for delivery by Belgian, Dutch, German, and Italian aircraft) and consolidating the remaining weapons at one or two U.S. bases in Europe, or something else remains to be seen. But a reduction rather than complete withdrawal would achieve little.

Heated Debate

The debate over the deployment in Europe is in full swing, recently triggered by the new German government’s decision to work for a withdrawal.

A paper by Franklin Miller, a former top-Pentagon official in charge of the deployment in Europe, and former NATO head George Robertson calling the German position dangerous was rejected as old-fashioned thinking on the New York Times’ opinion pages by Wolfgang Ischinger, Germany’s former foreign deputy foreign minister and chairman of the Munich Security Conference, and Ulrich Weisser, a former director of the policy planning staff of the German defense minister.

And suggestions by some supporters of continued deployment that Eastern European countries oppose withdrawal have suffered recently with Poland’s Prime Minister Radek Sikorski calling for the reduction and elimination of non-strategic nuclear weapons, and a report from the Polish Institute of International Affairs in March 2009 that appeared to question the need for the nuclear deployment.

Status of U.S. Nuclear Deployment in Europe

The U.S. Air Force currently deploys an estimated 150-200 U.S. nuclear bombs in 87 aircraft shelters at six bases in five countries, a reduction from approximately 480 bombs in 2001. The breakdown by country looks like this:

Additional Background: History of U.S. Nuclear Weapons in Europe

This publication was made possible by a grant from Carnegie Corporation of New York and Ploughshares Fund. The statements made and views expressed are solely the responsibility of the author.

 

The U.S. Air Force’s 701 Munitions Support Squadron at Kleine Brogel Air Base must protect and handle the nuclear weapons at the base.

 

An astounding statement by a Belgian defense official has pointed an unexpected light on the apparent location of nuclear weapons at the Kleine Brogel Air Base in Belgium.

After a group of peace activists climbed the base fence and made their way deep into an area assumed to store nuclear weapons, Ingrid Baeck, a chief spokesperson for the Belgian Ministry of Defense, bluntly told Stars and Stripes: “I can assure you these people never, ever got anywhere near a sensitive area. They are talking nonsense….It was an empty bunker, a shelter,” she said and added: “When you get close to sensitive areas, then it’s another cup of tea.”

Baeck did not go so far as to explicitly confirm or deny if there were nuclear weapons on the base, but the Belgium Ministry of Defense’s mission statement for the 10^th Tactical Wing clearly shows that it has a nuclear mission (see Figure 1).

Figure 1: Belgian 10th Tactical Wing Mission

The Belgian Ministry of Defense’s mission statement for the 10th Tactical Wing (10 W Tac) at Kleine Brogel clearly lists a nuclear mission. Emphasis added.

.
Shelter Searching

It is unclear whether Baeck as a spokesperson actually knows where the weapons are stored or if “sensitive area” only refers to the particular shelter the activists reached. But her statement that the activists “ever got anywhere near a sensitive area” inadvertently redirects the attention to the western area of the base.

Kleine Brogel has 26 Protective Aircraft Shelters (PAS) located in three clusters: Area 1 at the western part of the base with 11 shelters; Area 2 at the center of the base also with 11 shelters; and Area 3 at the eastern end of the base with four shelters (see Figure 2).

Figure 2: Nuclear Weapons Storage Areas

Estimated locations for nuclear weapons at Kleine Brogel Air Base have changed over the years. Click image for large version.

.
During the Cold War, nuclear weapons were stored in the Weapons Storage Area northeast of the base, while aircraft loaded with nuclear weapons stood alert in the shelters in Area 3.

Area 2 has long been the suspected nuclear weapons storage area, given its 11 shelters, pronounced fencing, and separation from the outer base perimeter. This is the area the activists managed to penetrate on January 31^st.

Baeck’s statement appears to draw the attention to Area 1 at the western end of the base where 11 shelters are clustered. It also has an additional fence perimeter that appears to have been improved since 2006, but the gates were open on a satellite image dated April 8, 2007. Moreover, the area is close to the outer base fence, with the busy N748 highway only 225 feet (68 meters) from one shelter and another shelter only 134 feet (40 meters) from a residential neighborhood. Jeffrey L also has an interesting photo interpretation.

Whether the nuclear shelters necessarily have to be in one cluster inside the same perimeter is unknown, although safety and management issues seem to suggest so.

The Weapons Security and Storage System (WS3)

Only 11 of the 26 Protective Aircraft Shelters at Kleine Brogel are equipped with the Weapons Storage Security System (WS3), a nuclear weapons storage system unique to Europe. The system at Kleine Brogel was completed in 1992.

The mechanical part of the WS3 includes a Weapons Storage Vault (WSV), a reinforced concrete foundation and a steel structure recessed into the floor of the shelter. The vault platform can be elevated out of the concrete foundation by means of an elevator drive system to provide access to the weapons in two stages or levels, or can be lowered into the floor to provide protection and security for the weapons. The floor slab is approximately 16 inches (40 cm) thick. Sensors to detect intrusion attempts are embedded in the concrete vault body.

Each of the 11 vaults can store up to four B61 bombs, but normally contains only one or two for a total of 10-20 bombs currently at Kleine Brogel.

Location of the vault inside the shelter depends on the size of the shelter and the proximity of conventional weapons storage racks. Two layouts are in use (see Figure 3), and the vaults at Kleine Brogel are the smaller located at the front-left end of the shelter.

Figure 3: Weapons Storage Vaul Locations

The location of the underground Weapons Storage Vault depends on the size of the aircraft shelter. Kleine Brogel shelters use the right-hand layout.

The vaults are rarely visible on photos from outside the shelters, but in this unique photo (see Figure 4) taken at nearby Volkel Air Base in the Netherlands in 2009 the outline of the vault can be seen in the front-left corner (right in the picture) of the shelter.

A vault cover is visible inside this shelter at Volkel Air Base in the Netherlands. The picture of the specially painted F-16 (no. J-015) was taken during a pilot ceremony in 2009. Reprinted with permission. Original photo at Touchdown Aviation.

.
The vault can be elevated in two stages, halfway to provide access to the top rack, or fully to provide access to the lower rack as well. An example of halfway elevation is the photo below showing the command of U.S. Air Forces in Europe, General Roger Brady, receiving a briefing next to a vault at Volkel Air Base in June 2008 (see Figure 5) (he also visited Kleine Brogel). The visits happened shortly after the Blue Ribbon Review report concluded that “most sites” storing nuclear weapons in Europe did not meet DOD security standards.

This picture, taken inside a shelter at Volkel Air Base, shows Gen. Grady receiving a briefing from a member of the 703rd MUNSS. The vault is halfway raised showing one B61 bomb, with the lower bomb rack hidden below the floor level.

.
If fully elevated the vault appears as on the image below (see Figure 6). The base name is unknown, but given the location of the vault it appears to be inside a large shelter at a U.S. base, possibly Aviano Air Base in Italy or Ramstein Air Base in Germany (all B61s were removed from Ramstein in 2005).

What is Security?

Kleine Brogel base commander Col. Fred Vansina insisted that the penetration of the base by the activists did not constitute a security incident: “Our installations are very well secured, in different ways,” there was “no single security incident, whatever the activists claim.”

A nuclear base is a sensitive area and unauthorized personnel meandering around deep inside its inner perimeters is a security incident, but Vansina’s definition appears to require an unauthorized and dangerous approach of a nuclear facility. Both he and Baeck have great confidence in the WS3 and the security forces’ ability to protect the weapons under all circumstances.

I agree that it would be very difficult for anyone to steal or destroy the weapons under normal circumstances when they’re stored underground. But it is the abnormal circumstances that concern me; weapons are occasionally brought up from the vault, serviced, and moved (see Figure 7). Overconfidence is dangerous because incidents and accidents have a nasty habit of happening in ways that were not anticipated. And that requires us to weigh the risks against the necessity of the deployment, a necessity I have an increasingly hard time to see.

The safety of the underground Weapons Storage Vault no longer applies when nuclear bombs in Europe are brought up for maintenance or transport. A 1997 Air Force study even found a risk of lightning causing a nuclear detonation.

Status of Nuclear Weapons in Europe

The 10-20 weapons at Kleine Brogel are part of a stockpile of an estimated 150-200 U.S. nuclear bombs scattered in 87 vaults at six bases in five countries, a reduction from approximately 480 bombs in 2001. My current estimate looks like this (see Figure 8):

Peace activists walked one kilometer onto a US nuclear weapons storage site in Belgium for more than one hour before security personnel reacted. Click image for larger version. (For an update to this map, go here)

.
By Hans M. Kristensen

A group of people last week managed to penetrate deep onto Kleine Brogel Air Base in Belgium where the U.S. Air Force currently deploys 10-20 nuclear bombs. (For an update to this blog, go here)

Fortunately, the people were not terrorists but peace activists from a group known as Vredesactie, who managed to climb the outer base fence, walk cross the runway, breach a double-fenced security perimeter, and walk into the very center of the air base alongside the aircraft shelters where the nuclear bombs are thought to be stored in underground vaults.

A Nuclear Cake Walk

The activists climbed the outer base fence (1), breached the inner double-fence (2), tagged a nuclear aircraft shelter (3), walked across the tarmac (4), before being arrested (5) after more than one hour inside the base. The numbers on the images correspond to the location of the numbers on the map above.

The activists penetrated nearly one kilometer onto the base over more than an hour before a single armed security guard appeared and asked what they were doing. Soon more arrived to arrest the activists, who later described: “The military blindfolded for hours, they forced us to kneel in the snow, arms outstretched at 90° and threatened us if we intend to return to the base in the months to come.”

The activists videotaped their entire walk across the base. The security personnel confiscated cameras, but the activists removed the memory card first and smuggled it out of the base. Ahem…

In June 2008, I disclosed how an internal Air Force investigation had concluded that most nuclear weapons sites in Europe did not meet US security requirements. The Dutch government denied there was a problem, and an investigative team later sent by the US congress concluded that the security was fine.

They might have to go back and check again.

The nuclear bombs at Kleine Brogel are part of a stockpile of about 200 nuclear weapons left in Europe after the Cold War ended. Whereas nuclear weapons have otherwise been withdrawn to the United States and consolidated, the bombs in Europe are scattered across 62 aircraft shelters at six bases in five European countries. The 130-person US 701^st Munitions Support Squadron (MUNSS) is based at Kleine Brogel to protect and service the nuclear bombs and facilities.

They might have to go back to training.

The activists will likely be charged with trespassing a military base but they should actually get a medal for having exposed security problems at Kleine Brogel. And this follows two years of the Air Force creating new nuclear command structures and beefing up inspections and training to improve nuclear proficiency following the embarrassing incident at Minot Air Force Base in 2007. Despite that, the activists not only made their way deep into the nuclear base but also discovered that the double-fence around the nuclear storage area had a hole in it! “We’re not the first,” one of the activists said.

NATO needs to get over its obsession with nuclear weapons and move out of the Cold War and the Obama administration’s upcoming Nuclear Posture Review needs to bring those weapons home before the wrong people try to do what the peace activists did.

On 13 January, Ivanka Barzashka and I gave a briefing at the AAAS on our work regarding Iran’s uranium enrichment capacity.  Joshua Pollack also gave a briefing, which he has described.  Joshua’s analysis is thorough and interesting but I think I would use a different distinction than the “actual” and “nominal” values that he defines.

Pollack shows how the estimates of the capability of Iran’s centrifuge, the IR-1, have declined over time.  That is intriguing but I worry that it makes the calculations that Ivanka and I and others have performed using data reported from International Atomic Energy Agency (IAEA) on-site inspections seem like the next step in a series of similar estimates.  They are not.  There are two very different types of approaches being taken here.  Here I present an analogy that I think might make the differences clear.

Katsuya Okada and Hillary Clinton met in September 2009.

By Hans M. Kristensen

The Japanese government has officially rejected claims made by some that Japan is opposed to the United States retiring the nuclear Tomahawk Land-Attack Missile (TLAM/N).

The final report of the Congressional Commission on the Strategic Posture of the United States from May 2009 emphasized the importance of maintaining the TLAM/N for extended deterrence in Asia by referring to private conversations with specifically “one particularly important ally” (read: Japan) that “would be very concerned by TLAM/N retirement.”

In a letter sent to Secretary of State Hillary Clinton on December 24, 2009, Japanese Foreign Minister Katsuya Okada explicitly says that the Japanese government has expressed no such views.

The Japanese Foreign Minister’s letter explicitly refers to the Commission: “It was reported in some sections of the Japanese media that, during the production of the report of the Congressional Commission on the Strategic Posture of the United States released in May this year, Japanese officials of the responsible diplomatic section lobbied your government not to reduce the number of its nuclear weapons, or, more specifically, opposed the retirement of the United States Tomahawk Land Attack Missile – Nuclear (TLAM/N) and requested that the United States maintain a Robust Nuclear Earth Penetrator (RNEP).

I don’t know who made a reference to RNEP (the Commission didn’t; perhaps it was a reference to earth-penetration capabilities in general rather than RNEP per ce), but Okada’s rejection of the TLAM/N claim is clear:

“[A]lthough the discussions were held under the previous Cabinet, it is my understanding that, in the course of exchanges between our countries, including the deliberations of the above mentioned Commission, the Japanese Government has expressed no view concerning whether or not your government should possess particular [weapons] systems such as TLAM/N and RNEP.” (my emphasis)

Okada’s statement suggests that he has checked the government’s files. It also matches the statement made by Admiral Timothy J. Keating, the former Commander of U.S. Pacific Command, in July 2009, that he was “unaware of specific Japanese interests in the” TLAM/N.

If the TLAM/N were retired, Okada says, Japan would of course like to be informed about how this would affect extended deterrence and how it could be supplemented. I hope “supplemented” means by other existing nuclear and non-nuclear means, not by new nuclear weapon system.

It seem so, because Okada writes that he favors nuclear disarmament, and he also expresses interest in the proposal made recently by the International Commission on Nuclear Non-Proliferation and Nuclear Disarmament (ICNND) – and many others – that the role of nuclear weapons be restricted to deterrence of the use of nuclear weapons. That is important for the Japanese government to say because one of the current missions for U.S. nuclear weapons involve North Korean chemical and biological attacks on Japan. Apparently, closer consultations between the United States and Japan on extended deterrence issues would be a good idea.

It seems more and more that the TLAM/N claim resulted from a shady collusion between a few U.S. and Japanese officials (some current and some former) who sought to present private views as more than that in an effort to put brakes on the Obama administration’s disarmament agenda.

Hopefully the pending Nuclear Posture Review will not be led astray.

Russia’s Teykovo 4 missile garrison northeast of Moscow is undergoing major upgrades for new SS-27 mobile nuclear missiles. Click image for large illustration of the changes.

.
By Hans M. Kristensen

The latest overview of Russia’s nuclear forces produced by Robert Norris from NRDC and myself is now available on the website of the Bulletin of the Atomic Scientists.

We estimate that Russia currently (January 2010) deploys approximately 4,600 nuclear weapons, down from roughly 4,800 a year ago. The arsenal includes some 2,600 strategic warheads and about 2,000 warheads for nonstrategic forces. Another 7,300 weapons are thought to be in reserve or awaiting dismantlement for a total inventory of approximately 12,000 nuclear warheads. We estimate the weapons are stored at 48 permanent storage sites.

SS-27 Modernization at Teykovo

One of the interesting developments is Teykovo northeast of Moscow where four missile garrisons are in the process of upgrading from the SS-25 road-mobile intercontinental ballistic missile (ICBM) to the newer SS-27. One base still has SS-25s while the other three are in various stages of upgrading.

The SS-27 comes in two versions: single-warhead SS-27 Mod 1 (Topol-M) and the multiple-warhead SS-27 Mod 2 (RS-24). The two versions can be deployed in silos or on mobile launchers. All Teykovo missiles are mobile. Fifteen SS-27 Mod 1s have already been deployed, and the Russian military stated repeatedly in 2009 that the first SS-27 Mod 2 (RS-24) would become operational at Teykovo by the end of the year, which we wrote in our overview. That apparently did not happen after all and the system is now expected to become operational sometime in early-2010.

Commercial satellite images taken over the past five years clearly show major construction work at the garrisons. The newest images from late-2009 show that two garrisons appear to be active, one is undergoing major upgrades (see image above), and one was inactive as of September 2009.

Teykovo 1 (56°48’33.11″N, 40°10’15.89″E) appears to be active with the SS-25. Nine launchers (one regiment) are deployed. A satellite photo from September 17, 2009, shows no construction. The base might be converted to SS-27 in the future.

Teykovo 2 (56°55’0.42″N, 40°18’31.39″E) no longer has operational SS-25s with all missile garages missing in a satellite image from September 17, 2009. No construction has begun but the base might be converted to SS-27 in the future.

Teykovo 3 (56°55’56.98″N, 40°32’38.47″E) appears to have almost completed its upgrade. Major construction occurred in 2006-2008 and some remaining construction is visible in a satellite image from September 6, 2009. Nine SS-27s are operational.

Teykovo 4 (56°42’15.10″N, 40°26’25.29″E) appears to be in the process of upgrading to SS-27, with six of eventually nine launchers apparently operational. Deployment of the first three SS-27 Mod 2 (RS-24) was scheduled for late-2009 but appears to have been delayed to later this year.

Modernization and Fear Mongering

Russian nuclear modernization is a hot topic in Washington with some trying to block new nuclear arms reductions by claiming that the United States is falling behind. That is fortunately far from the truth (see here and here) and the upgrade at Teykovo has been long in the coming and slow.

Like the United States, Russia is reducing its nuclear weapons but also modernizing its remaining forces. How the Kremlin plans to reconcile this modernization with the pledge to pursue nuclear disarmament that president Dmitry Medvedev made with his U.S. counterpart in 2009 will be interesting to see in the years ahead.
