It is worth your time reading Joe Cirincione’s article in Foreign Affairs: Obama’s Turn on Nuclear Weapons.

And I’m not just saying this because Joe is president of the Ploughshares Fund, one of my funders. He does a great job in describing the Obama administration’s ongoing nuclear targeting review and its place in the life of the administration with the myriads of policy issues and special interests that limit the president’s options in fulfilling the nuclear disarmament vision he presented in Prague in 2009.

That vision, as I wrote last week, was not visible in the Pentagon’s preview of it FY2013 defense budget request. It is an oversight that must be fixed. The defense budget must be in sync with U.S. nuclear policy, which now requires concrete steps to reduce the numbers and role of nuclear weapons.

The new defense budget has “no cuts” in nuclear forces.

By Hans M. Kristensen

“There are no cuts made in the nuclear force in this budget.” That clear statement was made yesterday by deputy defense secretary Ashton Carter during the Pentagon’s briefing on the defense budget request for Fiscal Year 2013.

We’ll have to see what’s hidden in the budget documents once they are released next month, but the statement is disappointing for anyone who had hopes that the administration’s promises about “concrete steps” to reduce the number and role of nuclear weapons and to “put an end to Cold War thinking” would actually be reflected in the new defense budget.

Not so for the FY13 budget. Other than a decision to delay work for two years on the next generation ballistic missile submarine, the Defense Budget Priorities and Choices report released yesterday does not list any nuclear reductions; neither previously announced nor new ones. Continue reading »

The Obama administration today presented a new defense strategy that it says is needed to realign U.S. military forces and doctrine with the reductions in combat operations in Iraq and Afghanistan as well as the new fiscal constraints created by the financial crisis.

There are few details in the new strategy for how this will be done but more will come in the Fiscal Year 2013 defense budget request expected in early February.

On nuclear forces the new strategy reaffirms the commitment to maintain a “safe, secure, and effective” nuclear arsenal as long as nuclear weapons exist. “We will field nuclear forces that can under any circumstances confront an adversary with the prospect of unacceptable damage, both to deter potential adversaries and to assure U.S. allies and other security partners that they can count on America’s security commitments.” The strategy appears heavily focused on the Pacific region and the Middle East. China and Iran, more so than North Korea, appear to be the primary potential adversaries, although Russian is by far the largest potential nuclear adversary.

In Prague in 2009, President Obama forcefully committed the United States “to seek the peace and security of a world without nuclear weapons,” that it was necessary to “ignore the voices who tell us that the world cannot change,” that the “United States will take concrete steps toward a world without nuclear weapons,” and that “To put and end to Cold War thinking, we will reduce the role of nuclear weapons in our national security strategy….” The New START treaty requires some reductions in deployed strategic forces, and the 2010 Nuclear Posture Review (NPR) reaffirmed the commitment to nuclear disarmament and further reducing the role of nuclear weapons.

The new defense strategy language comes across as somewhat timid, stating only: ”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.” This language presumably reflects the preliminary findings of the administration’s so-called Post-NPR Analysis, an ongoing effort within the administration to make “preparations for the next round of nuclear reductions” with Russia through ”potential changes in targeting requirements and alert postures.”

FAS has long argued that U.S. nuclear forces can and should be reduced further and that a sufficient nuclear deterrent can be maintained with far fewer weapons, lower operational readiness, and by changing the presidential guidance for how the military is required to plan for the potential use of nuclear weapons.

In Europe, which was the focus of U.S. strategy during the Cold War, FAS has argued that the demise of the Soviet threat and the fundamentally different security challenges requiring NATO’s attention today permit the withdrawal of the remaining U.S. nuclear weapons from Europe. The new U.S. defense strategy concludes that the changed security landscape allows changes in the European posture that, while maintaining the US security commitment to NATO, require development of a smarter posture that is better suited to meet the challenges of today’s world. Whether this language envisions a withdrawal of non-strategic nuclear weapons from Europe remains to be seen, but it appears to make make it harder to justify continued deployment.

It is important that the commitment in the new defense strategy to maintaining a nuclear deterrent does not overshadow the equally important commitment to reducing the size and role of nuclear forces. The clear message to other nuclear weapons states must be that the emphasis of U.S. policy is the nuclear disarmament trajectory described in Prague and that it is in their interest to follow the lead. Billions of dollars can be saved over the next decade by reducing the nuclear forces and removing nuclear doctrine further from the warfighting thinking that characterized the Cold War and which is still prevalent in today’s planning. That, not indefinite nuclear modernizations, ought to be the priority for the 21st century.

The Obama administration gets a medal for disclosing its New START treaty numbers.

.
By Hans M. Kristensen [updated 12 Dec 2011 with new bomber information]

Anyone familiar with my writings knows that I don’t hand out medals to the nuclear weapon states very often. But the Obama administration deserves one after the U.S. State Department’s recent release of the full U.S. aggregate data under the New START treaty.

The release breaks with the initial practice under the treaty of only publishing overall nuclear force category numbers, and re-establishes the U.S. practice from the previous START treaty of providing maximum disclosure of the strategic forces counted by the treaty. This is a good development that has gone totally unnoticed in the news media.

The pressure is now squarely on Russia to follow suit and publish its New START aggregate data as well. Continue reading »

New article published in Arms Control Today

.
By Hans M. Kristensen

The latest issue of Arms Control Today includes a new article by Robert Norris and myself about the nuclear targeting review that is currently underway in the Obama administration.

In ordering the review, formally known as the Post-NPR Review, President Obama has asked the military to review and revise U.S. nuclear strategy and guidance on the roles and missions of nuclear weapons, including potential changes in targeting requirements and alert postures, in preparation for the next round of nuclear reductions beyond the New START treaty with Russia.

Our article describes the bureaucratic labyrinth the review will go through before new presidential guidance emerges to change the U.S. nuclear war plan. To that end, we offer a wide range of suggestions for how the review could reduce the requirements for U.S. nuclear forces to “put an end to Cold War thinking,” as President Obama said in his Prague speech in 2009.

Hans Kristensen with B53 Bomb

By Katie Colten and Hans Kristensen

[Modifed] Today, one of the largest weapons in the United States nuclear weapons arsenal, the B53, will be dismantled at the Pantex Plant in Amarillo, Texas. Developed during the Cold War and deployed in 1962, this bomb weighs as much as a minivan and has an explosive yield of nine megatons, equivalent to 750 Hiroshima bombs.

Retired from the arsenal in 1997, the dismantlement of the B53 marks the end of the era of large, multi-megaton bombs, a hallmark of the Cold War. The largest-yield warhead in the U.S. stockpile today is the B83 bomb, which has a maximum yield of 1.2 Megatons.

Administration officials have been busy spinning the dismantlement as proof of the administration’s commitment to nuclear disarmament and as vindication of its plan to spend billions of extra dollars to modernize the nuclear weapons production complex. Continue reading »

New START aggregate numbers have been published by the United States and Russia.

.
By Hans M. Kristensen

The latest New START treaty aggregate numbers of strategic arms, which was quietly released by the State Department earlier last week, shows modest reductions and important changes in U.S. and Russian strategic nuclear forces.

Most surprisingly, the data shows that Russia has increased its number of deployed strategic nuclear warheads and is now again above the New START limit.

Because of the limited format of the released aggregate numbers, however, the changes are not explained or apparent. As a result, though not yet one year old, the New START treaty is already beginning to increase uncertainty about the status of U.S. and Russian nuclear forces. Continue reading »

In 1991, with the collapse of the Soviet Union and the end of the Cold War, the United States was armed with a stockpile of over 18,300 nuclear weapons.[1]  Since then, the US Air Force (USAF) has conducted a range of military operations while maintaining a nuclear deterrence capability.  Due to a nuclear warhead mishap in 2007, the Air Force reshaped its nuclear deterrence mission and created Air Force Global Strike Command (AFGSC).  While the establishment of AFGSC streamlined the effectiveness of US nuclear deterrence, Air Force doctrine still has failed to articulate its leadership requirements at the Non-Commissioned Officer and Company Grade Officer levels to successfully accomplish its mission.

There are not many public pictures showing the U.S. ballistic missile submarine visits to South Korea. This one apparently shows the USS John Marshall (SSBN-611) in Chinhae in 1979. The submarine carried 16 Polaris A3 missiles with a total of 48 200-kt warheads.

By Hans M. Kristensen

Back in the late-1970s, U.S. nuclear-armed ballistic missile submarines suddenly started conducting port visits to South Korea. For a few years the boomers arrived at a steady rate, almost every month, sometimes 2-3 visits per month. Then, in 1981, the visits stopped and the boomers haven’t been back since.

At the time the visits began, the United States also had several hundred nuclear weapons deployed on land in South Korea, but the submarine visits apparently were needed to further demonstrate that the United States was prepared to defend the south against an attack from the north.

After North Korea’s nuclear tests in 2006 and 2009, shelling of South Korean territory and the sinking of one of its warships, there have been reports recently that an increasing number of South Koreans want the United States to deploy nuclear weapons in South Korea again, after the last such weapons were withdrawn in 1991. They think it is necessary to deter North Korea.

Some analysts have even suggested that the United States should develop an improved nuclear earth penetrator to better threaten North Korean deeply buried targets, an idea that was previously proposed the Bush administration but rejected by Congress. Continue reading »

Note: This is the fourth of four posts analyzing the FY 2012 Stockpile Stewardship and Management Plan, each jointly produced by the Federation of American Scientists and Union of Concerned Scientists. See previous posts: 1, 2, 3.

The FY2012 SSMP repeats the promise made in numerous previous government documents and official statements: construction of new factories with greater warhead production capability might enable retirement of some “hedge” warheads after the “responsive complex” has come online in the early-2020s and thereby reduce the overall size of the stockpile.

Today, the United States has approximately 2,150 operational warheads and another 2,850 in the hedge, for a stockpile total of 5,000. The FY2011 SSMP stated (Annex D, p. 2) that the planned production complex would be able to support a stockpile of 3,000-3,500 warheads, a level 1,500-2,000 warheads below today’s stockpile. However, it did not provide a timetable or strategy for any such reductions.

The FY2012 SSMP does, however, place conditions on further reductions. The report states that the number of nuclear weapons in the nation’s stockpile “may be reduced…if planned LEPs are completed successfully, the future infrastructure of the NNSA enterprise is achieved, and geopolitical stability permits” (emphasis added). The first two items on this list will not be accomplished for at least twenty years, but the plan shows that production of “hedge” warheads will continue even after that.

Specifically, the FY2012 SSNP states that this new production capacity is required “regardless of the size of stockpile” and shows that NNSA now plans to produce W78 hedge warheads during the 2021-2024 W78 LEP and even “continue production of additional hedge warheads” through 2035.

NNSA Plans Production of More Hedge Warheads

Despite a promise that construction of new warhead production facilities will permit a reduction of the “hedge” of non-deployed warheads in the stockpile, the FY2012 SSMP shows that the new facilities will be used to produce “additional hedge warheads.” The key phrase is enlarged above. Click on image to see the original.

.
The chart hints that hedge warhead production might also be part of the other warhead LEPs in the NNSA plan. The reason for the additional W78 hedge production in 2025-2035 is not stated. Right now, there are approximately 600 W78s in the stockpile, of which 350 are in the hedge. Are they planning to increase the latter number? Or is that simply continuing production of the “common or adaptable” warhead that would be actually used in the W88 LEP later on? Have other LEPs not been performed on warheads in the hedge, but they will here? The answer is a mystery.

Yet the use of new warhead production facilities to produce additional hedge warheads undermines the administration’s message that the new facilities are needed to allow a reduction of the stockpile. It suggests that even with a new “responsive” warhead production complex, the future stockpile will still include a sizeable hedge of reserve warheads.

Additionally, although the SSMP states that these facilities are needed to “maintain a safe, secure, and reliable arsenal over the long term,” these facilities will not be operational until most of the currently planned Life Extension Programs are either completed or well underway. That makes the plan to use the new facilities to produce additional hedge warheads particularly problematic.
