The world’s approximately 23,300 nuclear weapons are stored at an estimated 111 locations in 14 countries, according to an overview produced by FAS and NRDC.

Nearly half of the weapons are operationally deployed with delivery systems capable of launching on short notice.

The overview is published in the Bulletin of the Atomic Scientists and includes the July 2009 START memorandum of understanding data. A previous version was included in the annual report from the International Panel of Fissile Materials published last month. Continue reading »

Claims that nuclear weapons need to be as safe as a coffee table might drive warhead replacement

By Hans M. Kristensen and Ivan Oelrich

The latest study from the JASON panel is an unambiguous rejection of claims made by the National Nuclear Security Administration (NNSA), the nuclear weapon labs, defense secretary Robert Gates, and U.S. Strategic Command (STRATCOM) that some or all U.S. nuclear weapons should be replaced to ensure the future reliability of the arsenal.

The executive summary of the study, Lifetime Extension Program (LEP), finds “no evidence that accumulation of changes incurred from aging and LEPs have increased risk to certification of today’s deployed nuclear warheads.”  The study concludes that the lifetime of today’s nuclear warheads “could be extended for decades, with no anticipated loss in confidence, by using approaches similar to those employed in LEPs today.”  [Emphasis added.]

The JASON appears to have prevented a wasteful and counterproductive nuclear warhead replacement program. Even so, we expect parts of the report’s conclusions to be used by proponents of nuclear warhead replacements in the months and years ahead.   Continue reading »

The First Committee of this year’s 64^th United Nations General Assembly (GA) just wrapped up a month of meetings.  The GA breaks up its work into six main committees, and the First Committee deals with disarmament and international security issues.  During the month-long meetings, member states give general statements, debate on such issues as nuclear and conventional weapons, and submit draft resolutions that are then voted on at the end of the session.  Comparing the statements and positions of the U.S. on certain votes from one year to the next can help gauge how an administration relates to the broader international community and multilateralism in general.  Similarly, comparing how other member states talk about the U.S. and its policies can give insight into how likely states may be to support a given administration’s international priorities.

US Senate consideration of a new biosecurity bill has been delayed to accommodate requests for additional information from the Administration.  The Weapons of Mass Destruction Prevention and Preparedness Act of 2009 (S.1649), introduced by Senators Lieberman and Collins at the Senate Homeland Security and Government Affairs Committee, seeks to overhaul the US response to biosecurity threats.  In particular, the legislation focuses on research into potentially dangerous infectious diseases.

Highly infectious diseases are currently designated as select agents and regulated by the Departments of Agriculture (diseases of plants and livestock) or Health and Human Services (human pathogens).  The new legislation would replace this single list with three “tiers”, and research using the most dangerous agents would be overseen by the Department of Homeland Security.  An amendment by Senator Claire McCaskill would allow DHS to shut down labs that do not comply with safety regulations.  However, the bill would also implement so-called personnel reliability programs, common in nuclear research, as a condition for researchers to access the labs.  Recent reports by the government’s National Science Advisory Board for Biosecurity and the National Academies’ Board of Life Sciences did not recommend such measures at this time.

Though Lieberman, who chairs the committee, has made the bill a top priority, it is unclear when time would permit consideration of the legislation on the Senate floor.

The new German government has announced that it wants to enter talks with its NATO allies about the withdrawal of the remaining U.S. nuclear weapons from Germany.

The announcement coincides with the Obama administration’s ongoing Nuclear Posture Review, which is spending an unprecedented amount of time pondering the “international aspects” of to what extent nuclear weapons help assure allies of their security.

Germany and many other NATO countries apparently don’t want to be protected by U.S. forward-deployed tactical nuclear weapons, which they see as a relic of the Cold War that locks NATO in the past and prevents it’s transition to the future. Continue reading »

No preemptive nuclear options, according to Secretary of State Hillary Clinton.

By Hans M. Kristensen

During an interview with Ekho Moskvy Radio last week, Secretary of State Hillary Rodham Clinton was asked if “the American [nuclear] doctrine incorporate[s] preemptive nuclear strikes against an aggressor?”

The Secretary’s answer was: “No, no.”

President Barack Obama, here shown speaking to the United Nations in September, is seeking to delay a UN Resolution calling for De-Alerting Nuclear Forces.

.
By Hans M. Kristensen

The Obama administration has asked four countries to postpone a resolution at the United Nations calling for reducing the alert-level of nuclear weapons.

The intervention apparently is intended to avoid the Obama administration having to vote against the resolution before the important Non-Proliferation Treaty Review Conference in May 2010 — on an issue Barack Obama promised to support when he ran for president.

The resolution, which was last adopted by the U.N. General Assembly with overwhelming support on December 2, 2008, calls for “further practical steps to be taken to decrease the operational readiness of nuclear weapons systems, with a view to ensuring that all nuclear weapons are removed from high alert status.” Continue reading »

Retirement of the W62 warhead, seen here at Warren Air Force Base, has been been delayed.

.
By Hans M. Kristensen

The Pentagon has missed the deadline set by the 2001 Nuclear Posture Review for the retirement of the W62 nuclear warhead.

Retirement of the warhead, which arms a portion of the 450 U.S. Minuteman III intercontinental ballistic missiles, was scheduled for completion in Fiscal Year 2009, which ended on September 30th.

But the Department of Defense has been unable to confirm the warhead has been retired, saying instead earlier today: “The retirement of the W62 is progressing toward completion.”

The 2001 Nuclear Posture Review decided that, “the W62 will be retired by the end of Fiscal Year 2009.”  The schedule was later reaffirmed by government officials and budget documents. But the February 2009 NNSA budget for Fiscal Year 2010 did not report a retirement but a reduction in “W62 Stockpile Systems” – meaning the warhead was still in the Department of Defense stockpile, adding that a final annual assessment report and dismantlement activities will be accomplished in FY2010.

Offloading of the W62 from the Minuteman force has been underway for the past several years. First deployed in 1970, the W62 has a yield of 170 kilotons and is the oldest and least safe warhead in the U.S. stockpile. It is being replaced on the Minuteman III by the 310-kiloton W87 warhead previously deployed on the MX/Peacekeeper missile.

Documents provided to the Federation of American Scientists by the US Attorney’s Office for the Southern District of New York provide additional details about the case against alleged arms trafficker Viktor Bout, but many important questions remain (publicly) unanswered. Below is a brief summary of these documents and their significance.
