Thanks to the efforts of Bill Burr at the National Security Archive, some of the veil covering U.S. nuclear war planning against China in the 1958 Taiwan Strait crisis now has been lifted by a declassified military study.

It shows that on the day after the Chinese began shelling the Quemoy islands on August 23, 1958, U.S. Air Force Headquarters apparently assured Pacific Air Forces “that, assuming presidential approval, any Communist assault upon the offshore islands would trigger immediate nuclear retaliation.” Yet President Dwight D. Eisenhower fortunately rejected the use of nuclear weapons immediately, even if China invaded the islands, and emphasized that under no circumstances would these weapons be used without his approval.

Caution against nuclear use didn’t mean not planning for it, however, and in the years after the Taiwan Strait crisis an enormous nuclear build-up occurred in the Far East. The numbers started to decline in the 1970s, and for a period during the 1980s and first half of the 1990s, nuclear planning against China was reduced to reserve force contingencies. In the past decade, however, China has again become a focus for U.S. nuclear strike planning.

The number of deterrence patrols conducted by Russia’s 11 nuclear-powered ballistic missiles submarines (SSBNs) decreased to only three in 2007 from five in 2006, according to our latest Nuclear Notebook published in the Bulletin of the Atomic Scientists.

In comparison, U.S. SSBNs conducted 54 patrols in 2007, more than three times as many as all the other nuclear weapon states combined.

The low Russian patrol number continues the sharp decline from the Cold War; no patrols at all were conducted in 2002 (see Figure 1). The new practice indicates that Russia no longer maintains a continuous SSBN patrol posture like that of the United States, Britain, and France, but instead has shifted to a new posture where it occasionally deploys an SSBN for training purposes.

The Chinese navy has deployed a Jin-class (Type 094) ballistic missile submarine to a new base near Yulin on Hainan Island on the South China Sea, according to a satellite image obtained by FAS. The image shows the submarine moored at a pier close to a large sea-entrance to an underground facility.

Also visible is a unique newly constructed pier that appears to be a demagnetization facility for submarines.

A dozen tunnels to underground facilities are visible throughout the base compound.

The satellite image, which has also been described in Jane’s Defense Weekly, was taken by the QuickBird satellite on February 27, 2008, and purchased by FAS from DigitalGlobe.

China’s nuclear weapons arsenal has increased by 25 percent since 2006, Pentagon reports indicate, due to deployment of new ballistic and cruise missiles.

By Hans M. Kristensen

The Pentagon’s 2008 annual report to Congress on China’s military power indicates, when compared with previous versions, that China has increased its nuclear arsenal by 25 percent since 2006. The increase has happened due to deployment of new long-range solid fueled ballistic missiles and cruise missiles.

Part of the increase can be expected to be offset by retirement of older liquid fueled missiles over the next several years, but the trend is toward a slightly larger arsenal in the future.

As a reminder of the tendency to estimate too much too soon, however, the 2008 report lowers the range estimates for all three types of China’s new long-range ballistic missiles, one of them by as much as 10 percent.

The recent Senate Armed Services Committee hearing on Air Force nuclear weapons safety was a welcome but long-overdue event. Internal reports about deteriorating nuclear weapon safety and surety in the Air Force have been accumulating since the early 1990s, but six nuclear weapons had to “disappear” for a day from Minot Air Force Base last August to get the Pentagon and Congress to finally pay attention. Had it not been for reporter Michael Hoffman at Military Times, the incident likely would have been filed away in secret cabinets as well.

Two internal investigations have identified numerous deficiencies in the handling and management of nuclear weapons within the military and have recommended substantial changes. Some of the obvious recommendations - such as not storing nuclear and conventional weapons in the same bunker and that personnel must follow the rules - have now been implemented. Others will require more effort.

Yet the investigations have revealed an inherent problem in post-Cold War nuclear planning: self-management and lack of independent oversight. Indeed, the investigations themselves appear to have been hampered by the same shortcomings. The result is an inherent conflict between scrutinizing and promoting the nuclear mission and a reluctance to change things too much.

As a consequence, the reviews recommend revitalizing the nuclear mission and returning the bombers to a heightened nuclear alert posture to improve safety, while missing the most obvious and effective fix: removing nuclear weapons from bomber bases and ending the operational nuclear bomber mission.

China’s entire fleet of approximately 55 general-purpose submarines conducted a total of six patrols during 2007, slightly better than the two patrols conducted in 2006 and zero in 2005.

The 2007 performance matches China’s all-time high of six patrols conducted in 2000, the only two years since 1981 that Chinese submarines conducted more than five patrols in a single year.

The new information, obtained by Federation of American Scientists from the U.S. Navy under the Freedom of Information Act, also shows that none of China’s ballistic missile submarines have ever conducted a deterrent patrol. Continue reading »

The W62 is the only nuclear warhead that has been publicly identified for elimination under the Bush administration’s secret nuclear stockpile reduction plan.

By Hans M. Kristensen

The While House announced earlier today that the President had “approved a significant reduction in the U.S. nuclear weapons stockpile to take effect by the end of 2007.” The decision reaffirmed an earlier decision from June 2004 to cut the stockpile “nearly 50 percent,” but moved the timeline up five years from 2012 to 2007.

Not included in the White House statement, but added by other government officials, is an additional decision to cut the remaining stockpile by another 15% percent, although not until 2012.

The announcement of these important initiatives unfortunately was hampered by Cold War secrecy which meant that government officials were not allowed to reveal how many nuclear weapons will be cut or what the size of the stockpile is. As a result, news media accounts were full of errors, and one can only imagine the misperceptions this misplaced secrecy creates in other nuclear weapon states.

The U.S. nuclear war plan that entered into effect in March 2003 included new executable strike options against regional states seeking weapons of mass destruction. (click on image to download PDF-version)

By Hans M. Kristensen

The 2001 Nuclear Posture Review (NPR) and White House guidance issued in response to the terrorist attacks against the United States in September 2001 led to the creation of new nuclear strike options against regional states seeking to acquire weapons of mass destruction, according to a military planning document obtained by the Federation of American Scientists.

Rumors about such options have existed for years, but the document is the first authoritative evidence that fear of weapons of mass destruction attacks from outside Russia and China caused the Bush administration to broaden U.S. nuclear targeting policy by ordering the military to prepare a series of new options for nuclear strikes against regional proliferators.

Responding to nuclear weapons planning guidance issued by the White House shortly after the terrorist attacks on September 11, 2001, U.S. Strategic Command created a series of scenario driven nuclear strike options against regional states. Illustrations in the document identify the states as North Korea and Libya as well as SCUD-equipped countries that appear to include Iran, Iraq (at the time), and Syria - the very countries mentioned in the NPR. The new strike options were incorporated into the strategic nuclear war plan that entered into effect on March 1, 2003.

The creation of the new strike options contradict statements by government officials who have insisted that the NPR did not change U.S. nuclear policy but decreased the role of nuclear weapons.

China’s new Jin-class SSBNs at Huludao shipyard. (click on image for higher-resolution picture)

By Hans M. Kristensen

The two new Jin-class SSBNs I discovered on Google Earth earlier this month have now been photographed in port by an anonymous photographer. The photograph, which has appeared on several Chinese web sites (here and here) and sent to me by David, clearly shows the features of what I estimated to be the Jin-class submarine.

China appears to have launched two more SSBNs.

By Hans M. Kristensen (BLOG UPDATED OCTOBER 10, 2007)

China appears to have launched two more ballistic missiles submarines from the Bohai shipyard at Huludao approximately 400 km east of Beijing. This could bring to three the number of Jin-class (Type 094) nuclear-powered ballistic missile submarines (SSBNs) launched by China in the past three to four years.

The two submarines were discovered during analysis of newly published commercial satellite images on Google Earth. This is the second time in three months that FAS has discovered new Chinese ballistic missile submarines on commercial satellite images. The first time was in July 2007, when the first Jin-class was disclosed on the FAS Strategic Security Blog.

The submarines on the new image have the same dimensions as the previous submarine.
