Welcome Back, Multiple Object Kill Vehicles
Ever since the United States began developing a missile defense system, the focus has been on pursuing a robust missile defense system. As not much progress has been made on boost phase interception, it becomes mandatory to study a technology that could make the midcourse system of the ballistic missile more vulnerable to enemy missile defense system. At present, with counter measures like decoys, chaffs, and multiple independently targetable re-entry vehicles (MIRVs), the mid-course phase of the ballistic missile becomes a complicated phase of interception. The Multiple Object Kill Vehicle (MOKV), a program of the United States, is believed to negate these challenges of the missile defense system in the mid-course phase.
Nuclear Security and Safety in America: A proposal on illicit trafficking of radioactive material and orphan sources
The special nature of nuclear energy requires particular safety and security conditions and stronger protective measures. The International Atomic Energy Agency (IAEA), as do other international and regional organizations, provides assessment, but it does not know a great deal about the security status of most Member States. It is necessary to learn of and determine the needs and concerns of a State for improving legal framework, reviewing detection of and response to illicit trafficking, and in order to develop a strategic plan that will enhance work that results in tangible improvements of security.
Nuclear law has an international dimension because the risks of nuclear materials do not respect borders. Terrorist acts defy the law; they don’t belong to a State. The possibility of transboundary impacts requires harmonization of policies, programs, and legislation. Several international legal instruments have been adopted in order to codify obligations of States in various fields, which can limit national legislation. There are legal and governmental responsibilities regarding the safe use of radiation sources, radiation protection, the safe management of radioactive waste, and the transportation of radioactive material.
The terrorist attacks of 11 September 2001 represented a clear challenge, but they must not stand as obstacles in the development of nuclear technology. It is necessary to reinforce these efforts in order to improve nuclear energy security, because energy is a vital issue that cannot wait.

NGOs AND THEIR ROLES IN THE VERIFICATION OF NUCLEAR AGREEMENTS – APRIL 2016
After finishing up his second MacArthur Foundation-sponsored research project on issues related to verifying a nuclear agreement with Iran, Christopher Bidwell, FAS Senior Fellow for Nonproliferation Law and Policy, and his team are now focused on a third project that will look at the increased role played by nongovernmental organizations (NGOs) in verifying compliance and noncompliance with nuclear nonproliferation obligations. Special attention will be paid to how the privacy rights of entities and individuals whose data are used to make a determination can be protected.
35 NOBEL LAUREATES CALL ON WORLD LEADERS TO TAKE ACTION ON NUCLEAR TERRORISM – MARCH 2016
In a letter dated March 26, 2016, 35 Nobel Laureates from physics, chemistry, and medicine urged national leaders attending President Obama’s fourth and final Nuclear Security Summit on March 31st to reduce the risk of nuclear or radiological terrorism to near-zero in three sectors. The signees stressed that because terrorist threats “cross national boundaries,” they “require the concerted work of all nations to prevent… terrorist acts from happening.” They also “urge” world leaders “to devote the necessary resources to make further substantial progress in the coming years to real risk reduction in preventing nuclear and radiological terrorism.” The letter, written by Dr. Burton Richter, a Nobel Laureate in physics and the Paul Pigott Professor in the Physical Sciences at Stanford University and Director Emeritus, Stanford Linear Accelerator Center, and Dr. Charles D. Ferguson, President of FAS, and list of signees is available online at: https://fas.org/wp-content/uploads/2016/03/nobel-laureates-letter-to-nss-march-20162.pdf.
REPORT: SUGGESTIONS ABOUT JAPAN’S NUCLEAR FUEL RECYCLING POLICY BASED ON U.S. CONCERNS – MARCH 2016
To date, Japan’s peaceful nuclear energy use has taken the form of a nuclear fuel recycling policy that reprocesses spent fuel and effectively utilizes the plutonium retrieved in light water reactors (LWRs) and fast reactors (FRs). With the aim to complete recycling domestically, Japan has introduced key technology from abroad and has further developed its own technology and industry. However, Japan presently seems to have issues regarding its recycling policy and plutonium management and, because of recent increasing risks of terrorism and nuclear proliferation in the world, the international community seeks much more secure use of nuclear energy. Yusei Nagata, an FAS Research Fellow from MEXT, Japan, analyzes U.S. experts’ opinions and concerns about Japan’s problem and considers what Japan can (and should) do to solve it..

REPORT: USE OF MICROBIAL FORENSICS IN THE MIDDLE EAST/NORTH AFRICA REGION – MARCH 2016
In this study, Christopher Bidwell and Dr. Randall Murch explore the use of microbial forensics as a tool for creating a common base line for understanding biologically-triggered phenomena, as well as one that can promote mutual cooperation in addressing these phenomena. A particular focus is given to the Middle East/North Africa (MENA) region, as it has been forced to deal with multiple instances of both naturally-occurring and man-made biological threats over the last 10 years. Although the institution of a microbial forensics capability in the MENA region (however robust) is still several years away, establishing credibility of the results offered by microbial forensic analysis performed by western states and/or made today in workshops and training have the ability to prepare the policy landscape for the day in which the source of a bio attack, either man-made or from nature, needs to be accurately attributed.

REPORT: USE OF ATTRIBUTION AND FORENSIC SCIENCE IN ADDRESSING BIOLOGICAL WEAPON THREATS – FEBRUARY 2016
The threat from the manufacture, proliferation, and use of biological weapons (BW) is a high priority concern for the U.S. Government. As reflected in U.S. Government policy statements and budget allocations, deterrence through attribution (“determining who is responsible and culpable”) is the primary policy tool for dealing with these threats. According to those policy statements, one of the foundational elements of an attribution determination is the use of forensic science techniques, namely microbial forensics. In this report, Christopher Bidwell and Kishan Bhatt, an FAS summer research intern and undergraduate student studying public policy and global health at Princeton University, look beyond the science aspect of forensics and examine how the legal, policy, law enforcement, medical response, business, and media communities interact in a bioweapon’s attribution environment. The report further examines how scientifically based conclusions require credibility in these communities in order to have relevance in the decision making process about how to handle threats.

THE NEW B61-12 GUIDED NUCLEAR BOMB – JANUARY 2016
From the start of the development of the new $10 billion B61-12 guided nuclear bomb, FAS has been at the forefront of providing the public with factual information about the status and capabilities of the program. In November 2015, Hans Kristensen, Director of the FAS Nuclear Information Project, was featured in a PBS Newshour program about the weapon where former STRATCOM commander and Vice Chairman of the Joint Chiefs of Staff General James Cartwright confirmed FAS assessments that the increased accuracy of the B61-12 could make it a more usable weapon [/blogs/security/2015/11/b61-12_cartwright/]. In early 2016, FAS and NRDC used a government video of a B61-12 test drop to analyze the bomb’s increased accuracy and earth-penetrating capability [/blogs/security/2016/01/b61-12_earth-penetration/]. The analysis was used in a New York Times feature article, “As U.S. Modernizes Nuclear Weapons, ‘Smaller’ Leaves Some Uneasy.” 1
DEPARTMENT OF DEFENSE CONFRONTS “CLIMATE CHANGE” – MARCH 7, 2016
The official entry of the term “climate change” in the latest revision of the Department of Defense Dictionary of Military and Associated Terms reflects a growing awareness of the actual and potential impacts of climate change on military operations. Steven Aftergood, Director of the FAS Project on Government Secrecy, reported in Secrecy News that according to a Pentagon directive issued in January 2016, “The DoD must be able to adapt current and future operations to address the impacts of climate change in order to maintain an effective and efficient U.S. military.” Among other things, the new directive requires the Under Secretary of Defense for Intelligence and the Director of National Intelligence to coordinate on “risks, potential impacts, considerations, vulnerabilities, and effects [on defense intelligence programs] of altered operating environments related to climate change and environmental monitoring.” In a report to Congress last year, the DoD said that “The Department of Defense sees climate change as a present security threat, not strictly a long-term risk.” Read Aftergood’s analysis in full here: /blogs/secrecy/2016/01/dod-climate/.
THE NEW NUCLEAR CRUISE MISSILE – OCTOBER-DECEMBER 2015
The FAS Nuclear Information Project provided the public with important analysis about the mission and capabilities of the new nuclear air-launched cruise missile the Air Force is developing: the Long-Range Standoff missile (LRSO). The analysis was the first to highlight an overview of the mission government officials say the missile is needed for, a mission that includes a worrisome nuclear war-fighting role [/blogs/security/2015/10/lrso-mission/]. Hans Kristensen was also quick to point out that a new long-range conventional air-launched cruise missile being deployed by the Air Force could do much of the LRSO mission and he recommended canceling the LRSO, a measure which would save $20-$30 billion [/blogs/security/2015/12/lrso-jassm/].
PAKISTANI NUCLEAR FORCES – OCTOBER 2015
FAS research on the status and modernization of Pakistan’s nuclear weapons was covered extensively in news media reports in connection with Pakistani Prime Minister Nawaz Sharif’s visit to Washington in October 2015. The FAS Nuclear Notebook, co-authored by Hans Kristensen and Robert S. Norris, FAS Senior Fellow for Nuclear Policy, published by the Bulletin of the Atomic Scientists, estimated that Pakistan’s nuclear arsenal has grown by 20 weapons since 2011 to 130 warheads presently, including new tactical nuclear weapons. The research was used by the New York Times in a background article, “U.S. Set to Sell Fighter Jets to Pakistan, Balancing Pressure on Nawaz Sharif,”2 and an editorial, “The Pakistan Nuclear Nightmare,”3 as well as by the Associated Press and Indian and Pakistani news media.

ODNI ISSUES TRANSPARENCY IMPLEMENTATION PLAN – OCTOBER 28, 2015
Transparency is not ordinarily a trait that one associates with intelligence agencies. But the Office of the Director of National Intelligence has released a transparency implementation plan that establishes guidelines for increasing public disclosure of information by and about U.S. intelligence. Based on a set of principles on transparency that were published earlier last year, the plan prioritizes the objectives of transparency and describes potential initiatives that could be undertaken. Thus, the plan aims “to provide more information about the IC’s governance framework; to provide more information about the IC’s mission and activities; to encourage public engagement [by intelligence agencies in social media and other venues]; and to institutionalize transparency policies and procedures.” FAS Secrecy News reports that the plan neither includes any specific commitments nor sets any deadlines for action. Moreover, it is naturally rooted in self-interest. Its purpose is explicitly “to earn and retain public trust” of U.S. intelligence agencies. Nonetheless, it has the potential to provide new grounds for challenging unnecessary secrecy and to advance a corresponding “cultural reform” in the intelligence community.

DOD SECURITY-CLEARED POPULATION DROPS AGAIN – OCTOBER 7, 2015
The number of people in the Department of Defense holding security clearances for access to classified information declined by 100,000 in the first six months of FY2015, recounts FAS Secrecy News. The latest available data show 3.8 million DoD employees and contractors with security clearances, down from 3.9 million earlier in 2015, and a steep 17.4 percent drop from 4.6 million two years ago. Furthermore, only 2.2 million of the 3.8 million cleared DoD personnel are actually “in access,” meaning that they have current access to classified information. Thus, further significant reductions in clearances would seem to be readily achievable by shedding those who are not currently “in access.” The total number of security-cleared persons government-wide is roughly 0.5 million higher than the number of DoD clearances, putting it at around 4.3 million, down from 5.1 million in 2013. The new DoD security clearance numbers were presented in the latest quarterly report on Insider Threat and Security Clearance Reform, FY2015 Quarter 3, September 2015. The reduction in security clearances is not simply a reflection of programmatic or budgetary changes – rather, it has been defined as a policy goal in its own right. A bloated security bureaucracy is harder to manage, more expensive, and more susceptible to catastrophic security failures than a properly streamlined system would be.

Navy Builds Underground Nuclear Weapons Storage Facility; Seattle Busses Carry Warning
![](https://fas.org/wp-content/uploads/2023/05/bangor-poster.jpg)
Seattle busses warn of largest nuclear weapons base. Click image to see full size.
The US Navy has quietly built a new $294 million underground nuclear weapons storage complex at the Strategic Weapons Facility Pacific (SWFPAC), a high-security base in Washington that stores and maintains the Trident II ballistic missiles and their nuclear warheads for the strategic submarine fleet operating in the Pacific Ocean.
The SWFPAC and the eight Ohio-class nuclear-powered ballistic missile submarines (SSBNs) homeported at the adjacent Bangor Submarine Base are located only 20 miles (32 kilometers) from downtown Seattle. The SWFPAC and submarines are thought to store more than 1,300 nuclear warheads with a combined explosive power equivalent to more than 14,000 Hiroshima bombs.
A similar base with six SSBNs is located at Kings Bay in Georgia on the US east coast, which houses the SWFLANT (Strategic Weapons Facility Atlantic) that appears to have a dirt-covered warhead storage facility instead of the underground complex built at SWFPAC. Of the 14 SSBNs in the US strategic submarine fleet, 12 are considered operational with 288 ballistic missiles capable of carrying 2,300 warheads. Normally 8-10 SSBNs are loaded with missiles carrying approximately 1,000 warheads.
To bring public attention to the close proximity of the largest operational nuclear stockpile in the United States, the local peace group Ground Zero Center for Nonviolent Action has bought advertisement space on 14 transit buses. The busses will carry the posters for the next eight weeks. FAS is honored to have assisted the group with information for its campaign.
The Limited Area Protection and Storage Complex
Although the new underground storage complex is not a secret – its existence has been reported in public navy documents since 2003 – it has largely escaped public attention until now.
The new complex is officially known as the Limited Area Protection and Storage Complex (LAPSC), or navy construction Project Number P973A. The complex was originally estimated to cost $110 million but ended up costing nearly $294 million.
The US Navy describes the complex as “a reinforced concrete, underground, multi-level re-entry body processing and storage facility” with “hardened floors, and hardened load-bearing walls and roof.” Glen Milner at the Ground Zero Center helped locate some of the budget documents. Other construction details provided by the navy further describe the complex as:
A 16,000-m2 [180,000 square feet] multi-level, underground, hardened, blast-resistant, reinforced concrete structure, with approximate dimensions of 110 meters long by 82 meters wide. Two tunnels (approximately 122 meters long, 6 meters wide, and 6 meters tall) will provide heavy vehicle access to and from the LAPSC. An aboveground portion of the facility will provide administrative and utility support spaces. Special features of the facility include: power-operated physical security and blast-resistant doors, TEMPEST shielded rooms, seven (7) overhead bridge cranes (2 ton capacity), three (3) elevators, lightning protection system, grounding system, liquid waste collection/retention system, emergency air purge system, fire protection systems, and multiple HVAC systems. This project will also provide a new 1000 kW emergency generator (enclosed within a new hardened, reinforced concrete structure), two security guard towers, lightning protection, utilities, and other site improvements. The existing Limited Area perimeter fence, security zone, and patrol roads will be expanded to encompass the new LAPSC.
The underground complex is similar to the general design of the large underground nuclear weapons storage facility Kirtland AFB in New Mexico, known as Kirtland Underground Munitions Storage Complex (KUMSC) – except KUMSC appears to be four times bigger than the SWFPAC complex. It appears to include 10 weapons storage bays (each 30 x 8 meters; 98 x 26 feet) where nuclear W76 and W88 warheads in their containers will be stored when they’re not deployed on submarines (see image analysis below).
![](https://fas.org/wp-content/uploads/2023/05/bangor-underground.jpg)

The primary building contractor, Ammann & Whitney, describes the unique blast doors and gas-tight features intended to ensure the safe storage and handling of the nuclear weapons:
The structures are reinforced concrete containment structures designed to withstand both interior and exterior explosions. All exterior penetrations and blast doors are gas-tight. There are a total of 24 blast doors; 12 are located in the above ground structures and 12 in the buried structure. All 12 doors in the above ground structures are subject to exterior blast loads while seven are subject to additional internal gas loads. Of the 12 doors in the buried structure, six doors are subject to blast loads from both sides, the remaining six are subject to blast loads from one side only but three must be gas-tight. Penetrations from the buried structure are blast resistant and gas-tight.
Design of the complex began in 2002, construction in 2007, and by 2009 the excavation and main outlines were clearly visible on satellite images. The complex was completed in 2012. Construction required enormous amounts of concrete. Over an 18-month period between December 2008 and mid-2010, for example, two hundred cement trucks entered the base every two weeks.
Nuclear weapon at SWFPAC were previously stored in above-ground earth-covered bunkers, or igloos, from where they were transported to two above-ground handling facilities for maintenance or for loading onto Trident II sea-launched ballistic missiles for deployment on operational SSBNs.
![](https://fas.org/wp-content/uploads/2023/05/bangor-mainarea.jpg)
But the navy has concluded that a “single underground protected structure provides the most robust protection for fulfilling this mission against all threats.” With the completion of the underground complex, the old surface facilities (2 handling buildings and 21 igloos) will be demolished (see site outline above).
![](https://fas.org/wp-content/uploads/2023/05/SSBN739.jpg)
The US Navy plans to operate nuclear-armed ballistic missile submarines at Naval Base Kitsap at least through 2080.
Over the next could couple of years the navy will “convert” four of the 24 missile launch tubes on each SSBN. The conversion will remove the capability to launch missiles from the four tubes, which no longer count under the New START treaty. The 384 excess warheads associated with the 24 missiles will likely be dismantled, leaving roughly 1,000 warheads at SWFPAC.
In the longer term (in the 2030s), the US Navy will transition to a new fleet of 12 SSBNs that will replace the current 14 Ohio-class SSBNs. Each of the new submarines will only carry 16 missiles, a reduction of an additional four tubes from the 20 left on the New START compatible SSBNs. Assuming seven of the 12 new SSBNs will be based at Bangor, that will leave 112 missiles with an estimated 896 warheads at SWFPAC and Bangor submarine base, or a reduction of about one-third of the warheads currently stored there.
Despite these expected reductions, the Naval Base Kitsap complex (the SWFPAC and Bangor submarine base) will remain the largest and most important nuclear weapons base in the United States for the foreseeable future.

Flawed Pentagon Nuclear Cruise Missile Advocacy
![LRSO-obama](/wp-content/uploads/2016/06/LRSO-obama.jpg)
The Pentagon is using flawed arguments to sell a nuclear cruise missile to President Obama?
By Hans M. Kristensen
In its quest to secure Congressional approval for a new nuclear cruise missile, the Pentagon is putting words in the mouth of President Barack Obama and spinning and overstating requirements and virtues of the weapon.
Last month, DOD circulated an anonymous letter to members of Congress after it learned that Senator Dianne Fenstein (D-CA) was planning an amendment to the FY2017 National Defense Authorization Act to put limits on funding and work on the new Long-Range Standoff (LRSO) nuclear air-launched cruise missile. The letter not surprisingly opposes the limits but contains a list of amazingly poor justifications for the new weapon.
The letter follows another letter in March from Under Secretary of Defense Frank Kendall to Senator John McCain that contains false claims about official documents endorsing the LRSO, as well a vague and concerning statements about the mission and purpose of the weapon.
The two letters raise serious questions about DOD’s justifications for the LRSO and Congress’ oversight of the program.
About That Strategy…
The DOD letter circulated to Congress in May presents surprisingly poor arguments in defense of the LRSO. In response to Senator Feinstein asking the Pentagon to show “the types of targets the LRSO is needed to destroy that cannot also be destroyed by existing U.S. nuclear and conventional weapons, “ DOD spins off into an off-topic, incoherent, and vague defense for retaining different nuclear capabilities in the arsenal:
Using the ability to destroy the target as the sole metric would also fail to address the dependence of effective deterrence on possessing credible options for responding to adversary attacks. A strategy of relying on large-scale or high-yield response options is credible and effective for deterring large-scale nuclear attack, particularly against the U.S. homeland, but it is less credible in the context of limited adversary use against an ally or U.S. forces operating abroad. Maintaining a credible ability to respond to a limited as well as large-scale nuclear attack against the United States or our allies strengthens our ability to deter such attacks from ever taking place.
But Feinstein’s draft amendment doesn’t say that destruction of the target is or should be “the sole metric” for deterrence. Even so, the bottom line for an effective nuclear deterrent is the credible capability to hold at risk the targets that an adversary values most. One can try to do that in many different ways, of course, but the DOD letter’s portrayal of an either-or choice between “large-scale or high-yield response options” against large attacks or limited-scale and lower-yield response options to limited adversary attacks is obviously a strawman argument because no one – certainly not Feinstein’s draft resolution – is arguing that the United States should eliminate its large inventory of lower-yield gravity bombs on heavy bombers and dual-capable fighter bombers. The US nuclear arsenal would still be able to provide limited and lower-yield options if the LRSO were canceled.
Next the DOD May letter tries to paint the LRSO decision as a choice between nuclear and non-nuclear weapons:
We do not and should not think of nuclear weapons as just another tool for destroying a target. The President’s guidance directs that [sic] DoD to assess what objectives and effects could be achieved through non-nuclear strike options, but also recognizes the unique contribution of nuclear weapons to our overall deterrence strategy. For example, the President might require a nuclear response to a nuclear attack in order to restore deterrence and prevent further attacks, even if a conventional weapon could also destroy the target.
This is another strawman argument because Feinstein’s draft amendment does not call for the elimination of all nuclear weapons or gravity bombs on heavy bombers and dual-capable fighter-bombers. Those weapons would of course still provide limited escalation-control options if the LRSO were canceled. Not to mention what non-nuclear cruise missiles could accomplish.
Next the DOD May letter gets into the obscure issue of “hedging” where multiple warhead types are used to provide backup against possible failure of one of them. I won’t go into a detailed analysis of hedging (Union of Concerned Scientists has a good report here) but critique the claims made in the DOD letter:
Requiring that only one warhead type is suitable for a given target also misses the LRSO’s critical role in providing the ability to hedge against significant geopolitical or technical issues. An effective bomber force with standoff capability can be put on alert in response to a serious technical problem in another leg of the Triad, or if the nature of the threat changes suddenly. Reliance on a single warhead type would threaten the stability of our deterrence posture, and would have changed the approach required for negotiating the New START Treaty with Russia.
The Feinstein draft amendment does not argue “that only one warhead is suitable for a given target” but asks for clarity about what the LRSO targets are that cannot also be destroyed by other existing nuclear or conventional weapons. That’s a reasonable question when someone is asking you to pay for a weapon that might cost $20 to $30 billion dollars over its lifetime.
But an effective bomber force does not require the LRSO to hedge. A force that includes 20 B-2 and 100 B-21 stealthy bombers (60 of them equipped with nearly 500 B61-12 gravity bombs) would still provide a considerable hedging capability against a serious technical problem in another leg of the Triad. Under the New START Treaty force structure the ICBMs are planned to deploy 400 warheads and the SLBMs 1,090 warheads.
However, the bomber hedging argument is weak. Under the Pentagon’s so-called 3+2 warhead plan (which is actually a 6+2 warhead plan according to a 2015 JASONs study), billions of dollars will be spent on building six new warhead types for the two ballistic missile legs partially to hedge against warhead failures on each other. So if the two ballistic legs are already designed to hedge each other, why are bomber weapons needed to hedge them as well? It sounds more like the Pentagon is using the hedge argument as a way to get the LRSO.
It is also amazing to see DOD bluntly advocating that the “bomber force with standoff capability can be put on alert… if the nature of the threat changes suddenly.” The bombers were taken off alert in 1991 and the Pentagon strongly argues against the dangers of rapidly increasing the alert level of nuclear forces.
The Kendall letter from March also defends the LRSO because it gives the Pentagon the ability to rapidly increase the number of deployed warheads significantly on its strategic launchers. He does so by bluntly describing it as a means to exploit the fake bomber weapon counting rule (one bomber one bomb no matter what they can actually carry) of the New START Treaty to essentially break out from the treaty limit without formally violating it:
Additionally, cruise missiles provide added leverage to the U.S. nuclear deterrent under the New Strategic Arms Reduction Treaty. The accounting rules for nuclear weapons carried on aircraft are such that the aircraft only counts as one weapon, even if the aircraft carries multiple cruise missiles.
It is disappointing to see a DOD official justifying the LRSO as a means to take advantage of a loophole in the treaty to increase the number of deployed strategic nuclear weapons above 1,550 warheads. Not least because the 2013 Nuclear Employment Strategy determined that the Pentagon, even when the New START Treaty is implemented in 2018, will still have up to one-third more nuclear weapons deployed than are needed to meet US national and international security commitments.
Finally, the DOD May letter also takes issue with the Feinstein draft resolution demand to certify that the sole objective of the LRSO is to deter nuclear attack. This would be inconsistent with the Administration’s nuclear weapons policy and the President’s guidance on nuclear employment, DOD says. Even though the NPR and guidance both affirmed that “the fundamental purpose of all U.S. nuclear weapons is to deter nuclear attack,” they also determined that a sole-purpose nuclear policy can not be adopted yet because there “remains a narrow range of contingencies in which U.S. nuclear weapons may still play a role in deterring a conventional or CBW attack against the United States or its allies and partners.”
The public DOD report on the 2013 guidance does not mention the “role in deterring a conventional or CBW attack” that the NPR specifies. And there are rumors that the guidance removed the requirement to plan nuclear missions against chemical weapons attacks. If so, that would leave only biological and conventional attacks other than nuclear attacks as a role for US nuclear weapons. Deterring biological attacks is thought to remain a mission because of the widespread human casualties such weapons can cause. And conventional might for example refer to a devastating North Korean conventional attack against Seoul or a Russian conventional attack against Eastern European NATO allies. But it is unclear and such attacks would in any case almost certainly be more likely to trigger non-nuclear responses; why would the US escalate to nuclear use if no one else has?
It is curious why Senator Feinstein chose the wording “sole objective” given that the NPR and guidance both clearly rejected a “sole purpose of nuclear weapons” for now (although the policy is to “work to establish conditions under which such a policy could be safely adopted”). She must have known that it would be easily rejected.
But it is also possible that what she was really after was a way to limit the almost tactical warfighting mission of the LRSO that numerous officials have widely described in public statements. Only a week after Kendall sent his LRSO letter to Senator McCain, Senator Feinstein said during a hearing:
The so-called improvements to this weapon seemed to be designed candidly to make it more usable, to help us fight and win a limited nuclear war. I find that a shocking concept. I think this is really unthinkable, especially when we hold conventional weapons superiority, which can meet adversaries’ efforts to escalate a conflict. (Emphasis added.)
The two DOD letters seem to confirm Senator Feinstein’s worst fears. The Kendall letter speaks of “flexible options across the full range of threat scenarios” with “multi-axis” attacks, and the DOD May letter talks about using “lower-yield” options in limited regional scenarios “even if a conventional weapon could also destroy the target.”
About Those Claims…
The Kendall letter, first published by Union of Concerned Scientists, makes numerous claims about official documents endorsing the LRSO. But when you check the documents, it turns out that they don’t explicitly endorse the weapon. Some don’t even mention it.
For example, Kendall claims that the 2010 Nuclear Posture Review “committed to maintaining a viable standoff nuclear deterrent for the air leg of the Triad…” But the NPR made no such commitment. The pubic version of the NPR only stated that “the Air Force will conduct an assessment of alternatives to inform decisions in FY 2012 about whether and (if so) how to replace the current air-launched cruise missile (ALCM)…” (Emphasis added). Contrary to Kendall’s claim, there is no explicit commitment in the public NPR to a nuclear cruise missile capability beyond the lifespan of the current ALCM.
Kendall also claims that the 2014 Nuclear Enterprise Review “committed to maintaining a viable standoff nuclear deterrent for the air leg of the Triad…” But that is also wrong. The public version of the document does not mention a cruise missile replacement at all but instead acknowledges “a moderate public attack on the need for the cruise missile carrying B-52 force…”
In terms of how the LRSO aligns with US nuclear employment strategy, the Kendall letter also explains that the DOD report Sustaining U.S. Global Leadership: Priorities for 21st Century Defense, to which President Obama provided the foreword, “reaffirmed the need for U.S. forces to project power and hold at risk any target at any location on the globe, to include anti-access and area denial environments.”
That may be so but neither the DOD report nor President Obama’s foreword mention a requirement for a nuclear cruise missile with one word. Instead, here is what the report says:
Project Power Despite Anti-Access/Area Denial Challenges. In order to credibly deter potential adversaries and to prevent them from achieving their objectives, the United States must maintain its ability to project power in areas in which our access and freedom to operate are challenged… Accordingly, the U.S. military will invest as required to ensure its ability to operate effectively in anti-access and area denial (A2/AD) environments. This will include implementing the Joint Operational Access Concept, sustaining our undersea capabilities, developing a new stealth bomber, improving missile defenses, and continuing efforts to enhance the resiliency and effectiveness of critical space-based capabilities.
On the same issue, President Obama’s foreword states:
As we end today’s wars and reshape our Armed Forces, we will ensure that our military is agile, flexible, and ready for the full range of contingencies. In particular, we will continue to invest in the capabilities critical to future success, including intelligence, surveillance, and reconnaissance; counterterrorism; countering weapons of mass destruction; operating in anti-access environments; and prevailing in all domains, including cyber.
Neither the DOD report nor Obama’s foreword makes any explicit commitment to a new nuclear cruise missile. Yet Kendall nonetheless uses them both to argue for one.
Humanitarian Crocodile Tears
The DOD May letter contains some really interesting statements about nuclear weapons and international law and collateral damage. The letter argues that not acquiring the LRSO would be “inconsistent with Administration policy and Presidential guidance” because the June 2013 Nuclear Employment Guidance “directs that all plans must apply the principles of distinction and proportionality and seek to minimize collateral damage to civilian populations and civilian objects.”
According to the 2013 Nuclear Employment Strategy report DOD sent to Congress in June 2013, the guidance “makes clear that all plans must also be consistent with the fundamental principles of the Law of Armed Conflict. Accordingly, plans will, for example, apply the principles of distinction and proportionality and seek to minimize collateral damage to civilian populations and civilian objects. The United States will not intentionally target civilian populations or civilian objects.”
This has been US policy for several decades but it is great that it was included in the new guidance. And it is even better if it actually restrains nuclear strike planning. But the authors of the DOD May letter forget to mention that even if the Obama administration were to cancel the LRSO, the Pentagon still plans to retain nearly 500 nuclear gravity bomb with lower yields for delivery by heavy bombers and dual-capable fighter-bombers. Retiring the ALCM or canceling the LRSO would not be incompatible with the guidance.
Yet the May letter illustrates how the new guidance is already being used by nuclear advocates in a twisted effort to use concern about civilian casualties in war as an argument against retiring existing nuclear weapons and to justify acquisition of new nuclear weapons that are more accurate with better lower-yield options to reduce radioactive fallout from nuclear attacks. The LRSO is one example; the B61-12 gravity bomb is another. As STRATCOM commander Gen. Robert Kehler told Congress in 2013 shortly after the guidance was published, “…we are trying to pursue weapons that actually are reducing in yield because we’re concerned about maintaining weapons that would have less collateral effect if the President ever had to use them.” (Emphasis added.)
“Electing to retire a lower-yield option because a higher-yield weapon can also destroy the target would be inconsistent with this principle and direction,” the DOD May letter concludes.
What makes this newfound “humanitarian” concern of the nuclear planners particularly hypocritical is that they don’t use the same guidance to conclude that the thousands of high-yield nuclear warheads on ICBMs and SLBMs therefore would be equally “inconsistent with Administration policy and Presidential guidance.”
Apparently, limiting damage to civilians is only worth it if you can get a better weapon in return.
Conclusions and Recommendations
It is the responsibility of the Pentagon to advocate for nuclear forces but this should also require it to have clear and valid justifications for why it needs them. The March letter from DOD’s Frank Kendall and the anonymous DOD letter from May arguing for why the Congress should approve and pay for the LRSO clearly fall short of that standard. Instead, they are full of false claims, spin, and vague and overstated assertions about its mission.
The scary part of this is that a majority in Congress appears to have accepted these poor justifications for the LRSO. The majority leadership in the Senate Armed Services Committee recently rejected an amendment by Senator Edward Markey to delay funding for the LRSO to allow Congress to better study the justifications. The rejection made use of many of the same false claims, spin, and vague overstatements that the DOD letters contain.
The DOD May letter rejecting Senator Feinstein’s draft amendment insisted that the LRSO Assessment of Alternative provided to Congress in 2014 “does not and should not address why we have an airborne standoff leg of the Triad,” and that the AoA therefore “only examined technical options to meet an air-based stand-off strategy in a cost and mission-effective manner.”
But then, in the next sentence, DOD essentially told the lawmakers that unless they approved more money for the LRSO program to advance it further, they cannot be told what the cost will be.
This is tantamount to blackmailing and wrong because several officials privately have said that they have already seen preliminary briefings on estimated life-cycle costs for both the LRSO missile and W80-4 warhead.
Providing false claims, spin, and vague overstatements about the requirements and mission of the LRSO is bad enough. But unless President Obama during his remaining time in office decides to cancel the LRSO program, it could end up costing the taxpayers $20-$30 billion over the lifetime of the weapon for a nuclear weapon the United States doesn’t need.

Briefing to Arms Control Association Annual Meeting
Yesterday I gave a talk at the Arms Control Association’s annual meeting: Global Nuclear Challenges and Solutions for the Next U.S. President. A full-day and well-attended event that included speeches by many important people, including Ben Rhodes, who is Deputy National Security Advisor for Strategic Communications in the Obama administration.
My presentation was on the panel “Examining the U.S. Nuclear Spending Binge,” which included Mark Cancian from CSIS, Amy Woolf from CRS, and Andrew Weber, the former U.S. Assistant Secretary of Defense for Nuclear, Chemical, and Biological Defense Programs. I was asked to speak about the enhancement of nuclear weapons that happens during the nuclear modernization programs and life-extension programs and the implications these improvement might have for strategic stability.
My briefing described enhancement of military capabilities of the B61-12 nuclear bomb, the new air-launched cruise missile (LRSO), and the W76-1 warhead on the Trident submarines. The briefing slides are available here:

Updated Nuclear Stockpile Figures Declassified
The size of the U.S. nuclear stockpile as of September 30, 2015 — 4,571 weapons — and the number of U.S. nuclear weapons that were dismantled in FY 2015 — 109 of them — were declassified and disclosed last week.
The latest figures came as a disappointment to arms control and disarmament advocates who favor sharp reductions in global nuclear inventories.
The new numbers “show that the Obama administration has reduced the U.S. stockpile less than any other post-Cold War administration, and that the number of warheads dismantled in 2015 was lowest since President Obama took office,” wrote Hans M. Kristensen in the FAS Strategic Security blog.
But precisely because the new disclosure casts an unflattering light on the Obama Administration, it also represents a triumph of transparency. Since it is at odds with the Administration’s own declared agenda, the release enables the press and the public to exact a measure of accountability.
“The new figures […] underscored the striking gap between Mr. Obama’s soaring vision of a world without nuclear arms, which he laid out during the first months of his presidency, and the tough geopolitical and bureaucratic realities of actually getting rid of those weapons,” wrote William J. Broad in the New York Times on May 26.
“Obama calls for end to nuclear weapons, but U.S. disarmament is slowest since 1980,” as a Washington Post headline put it on May 27.
News stories credited the Department of Defense for the “annual public release” of the stockpile information. But it is a bit more complicated than that.
The nuclear stockpile size was classified as “Formerly Restricted Data” (FRD) under the Atomic Energy Act. As such, it had to be cooperatively declassified by both the Department of Defense and the Department of Energy. And the declassification of FRD does not occur regularly or spontaneously.
“It is not the policy of the DoD/DOE to release such numbers automatically,” said Andrew Weston-Dawkes, the director of the DOE Office of Classification. Instead, consideration is given to declassification of specific information as it is requested. In this case, release of the 2015 stockpile figures was requested by the Federation of American Scientists in an October 2015 petition.
“The declassification of stockpile numbers was a direct result of your request for the information,” Dr. Weston-Dawkes wrote in an email. “Your request was reviewed by the DoD-FRD working group and in turn approved by the DoD and the DOE.”
Until the Obama Administration declassified it for the first time in 2010, the current size of the U.S. nuclear arsenal had never been officially made public. (Historical stockpile numbers up to 1961 were released in the 1990s.)
Columnists and commentators are in the habit of mocking President Obama’s promise that his would be the most transparent Administration in history. But when it comes to nuclear stockpile information, that promise has been fulfilled.
US Nuclear Stockpile Numbers Published Enroute To Hiroshima
![hiroshima_postcard](/wp-content/uploads/2016/05/hiroshima_postcard.jpg)
The mushroom cloud rises over Hiroshima on August 6, 1945, as the city is destroyed by the first nuclear weapon ever used in war.
By Hans M. Kristensen
Shortly before President Barack Obama is scheduled to arrive for his historic visit to Hiroshima, the first of two Japanese cities destroyed by U.S. nuclear bombs in 1945, the Pentagon has declassified and published updated numbers for the U.S. nuclear weapons stockpile and warhead dismantlements.
Those numbers show that the Obama administration has reduced the U.S. stockpile less than any other post-Cold War administration, and that the number of warheads dismantled in 2015 was lowest since President Obama took office.
The declassification puts a shadow over the Hiroshima visit by reminding everyone about the considerable challenges that remain in reducing excessive nuclear arsenals – not to mention the daunting goal of eliminating nuclear weapons altogether.
Obama’s Stockpile Reductions
The declassified data shows that the stockpile as of September 2015 included 4,571 warheads. That means the Obama administration so far has reduced the stockpile by 702 warheads (or 13 percent) compared with the last count of the Bush administration.
Although 702 warheads is no small number (other than Russia, no other nuclear-armed state has more than 300 warheads), the reduction constitutes the smallest reduction of the stockpile achieved by any previous post-Cold War administration (see table).
The declassified 2015 number is about 100 warheads lower than the number we estimated in our latest Nuclear Notebook. The reason for the difference is that the number of warheads retired in 2014-2015 turned out to be higher than the average retirement in the previous three-year period. The increase probably reflects a quicker than anticipated retirement of excess warheads for the navy’s Trident missiles.
It can be deceiving to assess stockpile reduction performance by only comparing numbers of warheads. After all, there are significantly fewer warheads left in the stockpile today compared with 1991 (in fact, 14,437 warheads fewer!) so why wouldn’t the Obama administration be retiring fewer warheads than previous post-Cold War administrations?
To overcome that bias we also compare the reductions in terms of the percentage the stockpile size changed during the various administrations. But even so, the Obama administration’s performance comes in significantly below that of all other post-Cold War administrations (see table).
Obama’s Dismantlements
The declassified numbers also show that the Obama administration last year only dismantled 109 retired warheads. This is the lowest number of warheads dismantled in any year President Obama has been in office. And it appears to be the lowest number dismantled by the United States in one year since at least 1970.
The National Nuclear Security Administration (NNSA) says the poor performance in 2015 was due to “safety reviews, unusually high lightning events, and a worker strike at Pantex.”
But the decrease cannot be explained simply as disturbances. Although 2015 was unusually low, the Obama administration’s dismantlement record clearly shows a trendline of fewer and fewer warheads dismantled (see table).
![dismantlements](/wp-content/uploads/2016/05/dismantlements.jpg)
Nuclear warhead dismantlement has decreased during the Obama administration. Click to view full size
There are currently roughly 2,300 retired warheads awaiting dismantlement, most of which were retired prior to 2009. NNSA says it plans to “increase weapons dismantlement by 20 percent starting in FY 2018” to be able to complete dismantlement of warheads retired prior to 2009 before the end of September 2021.
With the Obama administration’s average of about 280 warheads dismantled per year, it will take at least until 2024 before the total current backlog is dismantled. The several hundred additional warheads that will be retired before then will take several additional years to dismantle.
Yet in the same time period NNSA has committed to several other big warhead jobs that will compete with dismantlement work over the capacity at Pantex, including: complete production of the W76-1 by 2019, start up production of the B61-12 and W88 Alt 370 in 2020, preparation for the start up of the W80-4 in 2025, as well as the ongoing disassembly and reassembly for inspection of the existing warhead types in the stockpile.
Conclusion and Recommendations
President Obama’s visit to Hiroshima takes place in the shadow of his nuclear weapons legacy: he has reduced the U.S. nuclear weapons stockpile less than any other post-Cold War president and nuclear warhead dismantlement has declined on his watch.
For the arms control community (and that includes several important US allies, including Japan) the Obama administration’s modest performance on reducing the number of nuclear weapons – despite the New START Treaty – is a disappointment. Not least because the administration’s nuclear weapons modernization program has been anything but modest.
To be fair, it is not all President Obama’s fault. His vision of significant reductions and putting an end to Cold War thinking has been undercut by opposition ranging from Congress to the Kremlin. An entrenched and almost ideologically opposed Congress has fought his arms reduction vision every step of the way. And the Russian government has rejected additional reductions while New START is being implemented (although we estimate Russia during the Obama administration has reduced its own stockpile by more than 1,000 warheads).
Ironically, although Congress is vehemently opposed to additional nuclear reductions – certainly unilateral ones, the modernization plan Congress has approved has significant unilateral nuclear reductions embedded in it: a reduction of nuclear gravity bombs by one-half, a reduction of 48 sea-launched ballistic missiles beyond what’s planned under the New START Treaty, and unilateral reduction in the late-2020s of excess W76 warheads.
![alcm-launch](/wp-content/uploads/2016/05/alcm-launch.jpg)
The Air Force wants to build a new and better nuclear air-launched cruise missile even though the mission can be covered by conventional cruise missiles or other nuclear weapons. President Obama should cancel or delay the program and pursue a global ban on nuclear cruise missiles.
Curiously, there seems to have been less resistance to stockpile reductions from the U.S. military. The Pentagon’s Defense Strategic Guidance from 2012, for example, concluded: “It is possible that our deterrence goals can be achieved with a smaller nuclear force, which would reduce the number of nuclear weapons in our inventory as well as their role in U.S. national security strategy.”
Likewise, the Pentagon’s Nuclear Employment Strategy report sent to Congress in 2013 concluded that the nuclear force levels in place when the New START Treaty is fully implemented in 2018 “are more than adequate for what the United States needs to fulfill its national security objectives,” and that the United States “can ensure the security of the United States and our Allies and partners and maintain a strong and credible strategic deterrent while safely pursuing up to a one-third reduction in deployed nuclear weapons from the level established in the New START Treaty.”
And despite a significant turn for the worse in East-West relations, Russia is not increasing its nuclear arsenal but continuing to reduce it. But even if President Vladimir Putin decided to break out from the New START Treaty, the Pentagon concluded in 2012, Russia “would not be able to achieve a militarily significant advantage by any plausible expansion of its strategic nuclear forces, even in a cheating or breakout scenario under the New START Treaty, primarily because of the inherent survivability of the planned U.S. Strategic force structure, particularly the OHIO-class ballistic missile submarines, a number of which are at sea at any given time.” (Emphasis added.)
Those conclusions reveal a significant excess capacity in the U.S. nuclear arsenal that provides plenty of room for President Obama to do more in Hiroshima than simply remind of the dangers of nuclear weapons and reiterate the long-term vision of a world without them. Steps that he could and should take before leaving office include:
- Cancel plans to build a new nuclear air-launched cruise missile (the LRSO) or delay the plans as part of a focused effort to get international support for a global ban on nuclear cruise missiles;
- Retire now the majority of the gravity bombs scheduled to be retired in mid/late-2020s;
- Reduce now the number of ballistic missiles on U.S. strategic submarines to the lower number already planned for the Ohio replacement submarine in the 2030s;
- Retire now the excess sea-launched ballistic missile warheads scheduled to be retired in the mid/late-2020s;
- Reduce the ICBM force below the 400 planned under New START, probably to 300 as recommended by STRATCOM when Obama first took office;
- Reduce the alert level of U.S. nuclear forces to reduce risk of accidents and incidents, motivate Russia to also reduce its alert level, and to pave the way for an international effort to prevent other nuclear-armed states from increasing the readiness of their nuclear forces.
These actions would help bring U.S. nuclear policy back on track, remove excess capacity in the nuclear arsenal, restore the credibility of its arms control policy, retain a Triad of long-range nuclear forces, provide plenty of reassurance to allies and friends, maintain strategic stability, and free up resources for conventional forces. If Obama doesn’t do it, President Hillary Clinton will have to clean up after him.

Pentagon Report And Chinese Nuclear Forces
By Hans M. Kristensen
The Pentagon’s latest annual report on Chinese military developments mainly deals with non-nuclear issues, but it also contains important new information about developments in China’s nuclear forces. This includes:
- The size of China’s ICBM force has been relatively stable over the past five years
- China has deployed a new version of a medium-range ballistic missile
- A new intermediate-range ballistic missile is not yet deployed
- China’s SSBN fleet has yet to conduct its first deterrent patrol
- The possibility of nuclear capability for Chinese bombers
- Changes (or not) to Chinese nuclear policy
ICBM Developments
The future development of China’s ICBM force has been the subject of much speculation and projections over the years. Despite important new developments, this year’s report describes the size of the ICBM force as consistent with the force level reported over the past five years: around 60 launchers. Fielding of the DF-31 appears to have stalled and the data suggests that fielding of the DF-31A has been modest: so far about 20-30 launchers, enough for perhaps 4-5 brigades (see graph).
In 2012, the DOD report predicted that by 2015, “China will also field additional road-mobile DF-31A” launchers. But that doesn’t seem to have happened. Instead, the ICBM launcher force has remained relatively stable since 2011.
The number of ICBM launchers reported by the annual DOD reports over the past 13 years has fluctuated considerably, from around 30 in 2003 to 50 to 60-plus launchers in 2008 and later years. The uncertainty has been greatest in 2011-2013 and 2016 with a plus/minus of 25 launchers. That’s a significant uncertainty of approximately 40 percent in recent years versus around 10 percent in earlier years. But it seems clear that the Chinese ICBM forces is so far not continuing to grow.
While the number of launchers has been relatively stable, the DOD report shows a mysterious increase of missiles for those launchers: 75-100 missiles for 50-75 launchers. This is inconsistent with previous DOD reports, which have either listed the same number of launchers and missiles, or a slightly higher number of missiles because of a reload capability of the old DF-4 (see table).
It is unclear why the 2016 report suddenly increases the number of missiles to 25 more than the number of launchers. Neither the DF-5 nor the DF-31/31A ICBMs are thought to have reloads. Past DOD reports that included missile estimates always listed one reload for the DF-4, not any other system. With only about 10 DF-4 launchers left in the arsenal, the number of extra missiles in 2016 should probably be 10, not 25 (the 25 would fit better if there were two reloads for the DF-4). As far as I can tell, here is what the Chinese ICBM force looks like:
Despite many rumors in the public debate that China has developed or is developing rail-based versions of its ICBMs, there is no mentioning in the DOD report of any rail-based system. Here is out latest overview of Chinese nuclear forces. An update will be published in July.
DF-26 Nuclear Precision Strike?
China’s newest nuclear-capable missile, the DF-26 (DOD provides no CSS designation for the new missile) that was unveiled during the September 2015 parade in Beijing, appears not to have been deployed with missile units yet.
![DF-26](/wp-content/uploads/2016/05/DF-26.jpg)
Sixteen six-axel launchers were displayed during the parade and described as the official commentator as nuclear-capable. The missile is not yet deployed. Image: PLA.
The DOD report states that the DF-26, if it uses the same guidance for the nuclear and the conventional payloads, “would give China its first nuclear precision strike capability against theater targets.”
This statement indicates that DOD does not believe that any of China’s other nuclear-capable missiles have precision strike capability.
A New DF-21 Version?
The DOD report also lists a new version of the nuclear medium-range DF-21 missile but provides no details. The new version is called DF-21 Mod 6, or CSS-5 Mod 6 as it is listed in the report.
![DF-21_ex2016](/wp-content/uploads/2016/05/DF-21_ex2016.png)
The DOD report says China has deployed a new version of the DF-21 medium-range ballistic missile. Here a DF-21 takes part in a nuclear strike exercise in 2015. Image: PLA via CCTV-13.
The previous report from 2015 stated that the ICBM force was complemented by the “road-mobile, solid-fueled CSS-5 (DF-21) MRBM for regional deterrence missions.” The 2016 report, however, states that the ICBM force “is complemented by road-mobile, solid-fueled CSS-5 Mod 6 (DF-21) MRBM for regional deterrence missions,” the first time the Mod 6 designation has been used.
DOD does not provide any details about what the Mod 6 version is and to what extent it affects the status of the two original nuclear versions (Mod 1 and Mod 2). The original versions are getting old, so one possibility might be that the Mod 6 version is intended to replace them. But it is unclear what the status is.
DF-21 holds a special status in the history of Chinese forces because it was the first real mobile solid-fuel missile that replaced the old and more cumbersome liquid-fuel missiles. The Mod 1 was first fielded in the late-1980s although deployment didn’t really get underway until 1992. The Mod 2 was “not yet deployed” in 1998, according to NASIC, but both versions were listed as deployed by 2000. That was also the case in 2013, which suggest that the two versions might not be that different (perhaps range is the only difference), or that they are different but both retained for specific missions.
There is a lot of confusion about the different versions of the DF-21 in the public debate where many authors re-use secondary sources instead of relying on the original reference material. The most common mistake is to refer to the DF-21C conventional land-attack version as the CSS-5 Mod 3 and the DF-21D anti-ship version as the CSS-5 Mod 4. Over the years, DOD and the U.S. Intelligence Community have reported the following versions of the DF-21 medium-range ballistic missile:
DF-21 (CSS-5 Mod 1): nuclear
DF-21A (CSS-5 Mod 2): nuclear
DF-21C (CSS-5 Mod 4): conventional land-attack
DF-21D (CSS-5 Mod 5): conventional anti-ship
DF-21 (CSS-5 Mod 6): nuclear (new)
It is not clear what happened to DF-21B and/or CSS-5 Mod 3. In any case, the DF-21 has now completely replaced the old liquid-fuel DF-3As that dominated the Chinese regional nuclear deterrence posture since the early-1970s. The last brigade to convert to DF-21 possibly was the 810 Brigade at Dengshahe in Liaoning province.
About That Credible Sea-Based Deterrent
It seems that various news media reports and official statement continue to exaggerate or preempt the operational capability of the Chinese submarine force. Many have said the new Jin-class SSBNs had begun conducting deterrent patrols, but the DOE report seems to indicate that the subs (or rather, their missiles) are not yet fully operational.
In February 2015, for example, the U.S. Chief of Naval Operations, Vice Admiral Joseph Mulloy, reportedly told Congress that one SSBN had gone on a 95-day patrol. Later, STRATCOM Commander Admiral Cecil Haney said SSBNs had been at sea but that he didn’t know if they had nukes on board but had to assume they did.
In contrary to these statements, the DOD report states the Jin-class SSBN “will eventually carry” the JL-2 SLBM (apparently it doesn’t yet do so) and that “China will probably conduct its first SSBN nuclear deterrence patrol sometime in 2016.” So apparently not yet.
This “not quite yet” assessment was supported by the Defense Intelligence Agency saying “the PLA Navy deployed the JIN-class nuclear-powered ballistic missile submarine in 2015, which, when armed with the JL-2 SLBM, provides Beijing its first sea-based nuclear deterrent.” (Emphasis added.)
So one or more SSBNs might have sailed on some kind of deployment, but not necessarily with nuclear weapons onboard. All four operational Jin SSBNs are based at Longpo (Yulin) Submarine Base on Hainan Island, along with two Shang-class nuclear-powered attack submarines. A fifth Jin SSBN is under construction.
The DOD report also seems to debunk a rumor that China is building up to five additional Jin-class SSBNs. The head of US Pacific Command in 2015 told Congress that in addition to the submarines already launched, “up to five more may enter service by the end of the decade.” That seems to have been a fluke. The DOD report says a fifth Jin is under construction after which China will probably move on to a next-generation SSBN (Type 096) armed with a new missile (JL-3).
Nuclear Bombers?
The DOD report for the first time raises the issue of a potential nuclear role for the bombers. It does so by referencing various Chinese writings but without presenting a clear U.S. Intelligence Community conclusion about such a capability:
![china-bomb1967](/wp-content/uploads/2016/05/china-bomb1967.jpg)
A thermonuclear bomb is dropped from an H-6 bomber in June 1967.
“In 2015, China also continued to develop long-range bombers, including some Chinese military analysts have described as “capable of performing strategic deterrence”—a mission reportedly assigned to the PLA Air Force in 2012. There have also been Chinese publications indicating China intends to build a long-range “strategic” stealth bomber. These media reports and Chinese writings suggest China might eventually develop a nuclear bomber capability. If it does, China would develop a “triad” of nuclear delivery systems dispersed across land, sea, and air—a posture considered since the Cold War to improve survivability and strategic deterrence.”
Chinese bombers are normally not considered to have an active nuclear role and the “strategic deterrence” mission assigned to PLAA in 2012 could potentially also reflect the introduction of conventional land-attack cruise missiles on the modified H-6K bomber. Yet a US Air Force Global Strike command briefing in 2013 listed the new CJ-20 air-launched land-attack cruise missile carried by the H-6K as nuclear-capable.
And China in the past certainly developed the capability to deliver nuclear weapons from bombers. Between 1965 and 1979, bombers delivered the nuclear weapon for at least 12 of China’s nuclear test explosions. These tests involved both fission and thermonuclear weapons with yields ranging from 5-10 kilotons, a few hundred kilotons, to 2-4 megatons. The bombs were delivered by H-6 bombers (still in service and being modernized), H-5 bombers (retired), and Q-5 fighter-bombers (nearly all retired).
The Military Museum in Beijing apparently has on display models of at least two nuclear bomb designs: a fission bomb and a hydrogen bomb. This video shows what is said to be China’s first test of a thermonuclear bomb, delivered by an H-6 bomber in June 1967.
![china-bombs](/wp-content/uploads/2016/05/china-bombs.jpg)
Two nuclear bomb models are displayed in Beijing, the first fission bomb (left) and the first thermonuclear bomb (right). The marking on the thermonuclear bomb H639-23 is similar to those on the bomb used in the nuclear test on June 17, 1967: H639-6. Image: news.cn
Nuclear Policy and Strategy
Finally, the DOD report also summarizes the US understanding of Chinese nuclear policy and strategy.
The first is that the PLA has deployed new command, control, and communications capabilities to its nuclear forces to improve control of multiple units in the field. “Through the use of improved communications links,” DOD concludes, “ICBM units now have better access to battlefield information and uninterrupted communications connecting all command echelons. Unit commanders are able to issue orders to multiple subordinates at once, instead of serially, via voice commands.”
This is intended to improve control of the units but also to enhance their combat effectiveness in a crisis situation. To that end the DOD report mentions recent press accounts that China “may be enhancing peacetime readiness for nuclear forces to ensure responsiveness.” Part of this debate reflects a report by Gregory Kulacki citing Chinese military documents and statements that the nuclear forces may move towards a “launch-on-warning” posture to be able to launch missiles before they can be destroyed.
Despite these problematic developments, the DOD report concludes that there are no signs that China’s no-first-use policy and negative security assurance have been changed.
In other words, while Chinese nuclear policy itself does not appear to have changed, the way China deploys and operates its nuclear forces appears to be evolving significantly.

President’s Message: Reinvention and Renewal
From its inception 70 years ago, the founders and members of the Federation of American Scientists were reinventing themselves. Imagine yourself as a 26-year old chemist having participated in building the first atomic bombs. You may have joined because your graduate school adviser was going to Los Alamos and encouraged you to come. You may also have decided to take part in the Manhattan Project because you believed it was your patriotic duty to help America acquire the bomb before Nazi Germany did. And even when Hitler and the Nazis were defeated in May 1945, you continued your work on the bomb because the war with Japan was still raging in the Pacific. Moreover, by then, you may have felt like Dr. J. Robert Oppenheimer, the Scientific Director, that the project was “technically sweet”—you had to see it through to the end.
But when the end came—the atomic bombings of Hiroshima and Nagasaki—in August 1945, you may have had doubts about whether you should have built the bombs, or you may have at least been deeply concerned about the future of humanity in facing the threat of nuclear destruction. What should you then do? About a thousand of the “atomic scientists” throughout the country at various sites, such as Los Alamos, Oak Ridge, Hanford, and Chicago began to organize and discuss the implications of this new military technology.1
This political activity was not natural for scientists. Almost all of the founders of FAS were so-called “rank-and-file” scientists in their 20s and 30s. Members of this youth brigade—led by Dr. Willie Higinbotham, who was in his mid-30s but who looked younger—arrived in Washington. With their “crew cuts, bow ties, and tab collars [testifying] to their youth,” they roamed the halls of Capitol Hill, educating Congressmen and their staffs.2 Newsweek called them the “reluctant lobby.” As a history of the Atomic Energy Commission (AEC) notes, “Part of their reluctance stemmed from their conviction that the cause of science should not be dragged through the political arena.”3
Fortunately, these scientists persisted and achieved the notable result of successfully lobbying for civilian control of the AEC. While they also wanted international control of nuclear energy, they fell short of that goal. However, they were indefatigable in their educational efforts on promoting peaceful uses of nuclear energy and warning about the dangers of nuclear arms races.
Throughout FAS’s seven decades, the organization has transformed itself into various incarnations depending on the issues to be addressed and the resources available for operating FAS. To learn about this continual reinvention, I invite you to read all the articles in this special edition of the Public Interest Report. This edition has an all-star list of writers—many of whom have served in leadership roles at FAS and others who have deep, scholarly knowledge of FAS. These authors discuss many of the accomplishments of FAS, but they also do not shy away from mentioning several of the challenges faced by FAS.
What will FAS achieve and what adversities will occur in the next 70 years? As scientists know, research results are difficult, if not impossible, to predict. However, we do know that the mission of FAS is as relevant as ever, perhaps even more so than it was 70 years ago. Nuclear dangers—the founding call to action—have become more complex; instead of one nuclear weapon state in 1945, there are now nine countries with nuclear arms. Instead of a few nuclear reactors in 1945, today there are more than 400 power reactors in 31 countries and more than 100 research reactors in a few dozen countries. Moreover, some non-nuclear weapon states have acquired or want to acquire uranium enrichment or reprocessing facilities that can further sow the seeds of future proliferation of nuclear weapons programs. For these dangers alone, FAS has the important purpose to serve as a voice for scientists, engineers, and policy experts working together to develop practical means to reduce nuclear risks.
FAS has also served and will continue to serve as a platform for innovative projects that shine spotlights on government policies that work and don’t work and how to improve these policies. In particular, for a quarter century, the Government Secrecy Project, directed by Steve Aftergood, has worked to reduce the scope of official secrecy and to promote public access to national security information.

FAS has also contributed to the public debate on bio-safety and bio-security. Daniel Singer (one of the contributors to this issue) and Dr. Maxine Singer have been active for more than 50 years in bio-ethics. Dr. Barbara Hatch Rosenberg and Dorothy Preslar in the 1990s and early 2000s worked through FAS to develop methods (such as an email list serve, which was cutting edge in the 1990s) to connect biologists and public health experts around the globe to identify, monitor, and evaluate emerging diseases. In recent years, Chris Bidwell, Senior Fellow for Law and Nonproliferation Policy, has led projects examining potential biological attacks or outbreaks and the forensic evidence needed for a court of law or government decision making in countries in the Middle East and North Africa. The Nuclear Information Project, directed by Hans Kristensen, continues its longstanding work on providing the public with reliable information and analysis on the status and trends of global nuclear weapons arsenals. Its famed Nuclear Notebook, co-authored by Kristensen and Robert S. Norris, a senior fellow at FAS, is one of the most widely referenced sources for consistent data about the status of the world’s nuclear weapons.
I believe the greatest renewal and reinvention of FAS has been emerging in the past three years with the creation of networks of experts to work together to prevent threats from becoming global catastrophes. FAS has organized task forces that have provided practical guidance to policy makers about the implementation of the agreement on Iran’s nuclear program and that have examined the benefits and risks of the use of highly enriched uranium in naval nuclear propulsion. As I look to the next 70 years, I foresee numerous opportunities for FAS to seize by being the bridge between the technical and policy communities.
I am very grateful for the support of FAS’s members and donors and encourage you to invite your friends and colleagues to join FAS. Happy 70th anniversary!
The Legacy of the Federation of American Scientists
The Federation of American Scientists (FAS) formed after the bombing of Hiroshima and Nagasaki, precisely because many scientists were genuinely concerned for the fate of the world now that nuclear weapons were a concrete reality. They passionately believed that, as scientific experts and citizens, they had a duty to educate the American public about the dangers of living in the atomic age. Early in 1946, the founding members of FAS established a headquarters in Washington, D.C.,and began to coordinate the political and educational activities of many local groups that had sprung up spontaneously at universities and research facilities across the country. The early FAS had two simultaneous goals: the passage of atomic energy legislation that would ensure civilian control and promote international cooperation on nuclear energy issues, and the education of the American public about atomic energy. In addition, from its very inception, FAS was committed to promoting the broader idea that science should be used to benefit the public. FAS aspired, among other things, “To counter misinformation with scientific fact and, especially, to disseminate those facts necessary for intelligent conclusions concerning the social implications of new knowledge in science,” and “To promote those public policies which will secure the benefits of science to the general welfare.”
Scientists and Nuclear Weapons, 1945-2015
On August 8, 2015, twenty-nine scientists sent a letter to President Obama in support of the agreement with Iran that would block (or at least significantly delay) Iran’s pathways to obtain nuclear weapons. This continues a tradition that began seventy years ago of scientists having a role in educating the public, advising government officials, and helping shape policy about nuclear weapons.
Soon after the end of World War II, scientists mobilized themselves to address the pressing issues of how to deal with the many consequences of atomic energy. Of prime importance was the question of which government entity would control the research, development and production of atomic weapons, and any peaceful applications. Would it be the military, as it was during World War II, or a civilian agency, such as the newly created Atomic Energy Commission (AEC)?
