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.

The mysterious DF-41 missile did not appear at the Chinese National Day parade on October 1st, but the Chinese Ministry of National Defense says the DF-31A did. But did it, or was it in fact the DF-31?

By Hans M. Kristensen

The military parade at China’s 60th National Day celebration last week was widely rumored to be displaying a new long-range ballistic missile described in the news media as the DF-41. The rumors turned out to be, well, rumors.

Instead the Chinese Ministry of National Defense identified two other missiles: the nuclear DF-31A and the conventional DF-21C, to my knowledge a first.

But was it the DF-31A that rolled across the square or the shorter-range DF-31 already displayed ten years ago at the 1999 parade?

This past Thursday and Friday marked the 6^th bi-annual Article XIV Conference, the Conference on Facilitating the Entry Into Force of the Comprehensive Nuclear Test Ban Treaty (CTBT).  This year’s conference was held at the United Nations in New York and was met with a measure of cautious optimism – most states voiced their appreciation of President Obama’s pledge to work toward US ratification of the CTBT, while many states recognized the challenges of obtaining all the necessary ratifications for entry into force of the Treaty and mentioned the challenges to the nonproliferation regime stemming from the lack of the Treaty’s entry into force (despite former commitments to do so) and from the DPRK’s 2006 and 2009 nuclear tests.

Entry into force of the CTBT has been on the international agenda for thirteen years. Because the US, China, UK, France, and Russian Federation have all imposed a voluntary moratorium on national nuclear testing, many question the need for entry into force of the CTBT.  Although the Treaty would bring few new tangible benefits, the political impact of entry into force would be tremendous.  As explained below, the vast majority of sates see entry into force of the CTBT as somewhat of a litmus test for the future viability of the nonproliferation regime.

On Friday, President Obama announced that the United States knows of a new, undeclared, and hidden underground gas-centrifuge uranium enrichment facility in Iran, near the city of Qom.  Some news reports suggest that 3000 centrifuges will be housed there.  How significant is this discovery?  Well, just in time, our crack FAS researcher, Ivanka Barzashka, has posted on the FAS website a calculator to help you answer questions just like that.

President Obama has once again pushed nuclear weapons, and his vision for a world free of nuclear weapons, to the center of the world’s stage with his speech yesterday before the United Nations’ General Assembly and his chairing of the United Nations’ Security Council meeting this morning. He reiterated his goal of ratifying the Comprehensive Test Ban Treaty (CTBT), of negotiating a Fissile Material Cutoff Treaty (FMCT) that would end production of bomb-grade nuclear material (something the Bush administration supported in theory but without any verification procedures), of negotiating a treaty with Russia that will “substantially reduce” strategic nuclear warheads, and of strengthening the Non-Proliferation Treaty (NPT). The President also said “We will complete a Nuclear Posture Review that opens the door to deeper cuts, and reduces the role of nuclear weapons.” This morning, as chair of the UN Security Council, the President got unanimous consent to Council resolution that endorsed all the points made before the General Assembly.

The President’s remarks are powerful and plain and were overwhelming well received by all of us who have long hoped that the world might someday be free of nuclear weapons. Still, I am worried that the message has been clearer at the UN, and in Prague, than it is here in Washington. If we look at the direction the bureaucracy and politics are taking here, there is reason to worry that the President’s vision will be dangerously diluted. Continue reading »

Pakistan’s nuclear weapons stockpile now includes an estimated 70-90 nuclear warheads, according to the latest Nuclear Notebook published in the Bulletin of the Atomic Scientists. The estimate is an increase compared with the previous estimate of approximately 60 warheads due to Pakistan’s pending introduction of a new ballistic missile and cruise missiles.

The increase in the warhead estimate does not mean Pakistan is thought to be sprinting ahead of India, which is also increasing its stockpile. Continue reading »

The French nuclear-powered aircraft carrier Charles de Gaulle with air wing on deck.

By Hans M. Kristensen

France no longer deploys nuclear weapons on its aircraft carrier Charles de Gaulle under normal circumstances but stores the weapons on land, according to French officials.

President Nicolas Sarkozy declared in March 2008 that France “could and should be more transparent with respect to its nuclear arsenal than anyone ever has been.” But while the other nuclear powers declared long ago that their naval weapons were offloaded or scrapped after the Cold War ended, a similar announcement has – to my knowledge – been lacking from France.

The French acknowledgment marks the end of peacetime deployment of short-range nuclear weapons at sea.

It is not clear when the French offload occurred; it may have been instigated years ago. But it completes a worldwide withdrawal of short-range nuclear weapons from the world’s oceans that 20 years ago included more than 6,500 British, French, Russian, and U.S. cruise missiles, anti-submarine rockets, anti-aircraft missiles, depth bombs, torpedoes and bombs.
