China is building more than 100 new missile silos in its western desert, analysts say

MSN:

China has begun construction of what independent experts say are more than 100 new silos for intercontinental ballistic missiles in a desert near the northwestern city of Yumen, a building spree that could a signal a major expansion of Beijing’s nuclear capabilities.

Commercial satellite images obtained by researchers at the James Martin Center for Nonproliferation Studies in Monterey, Calif., show work underway at scores of sites across a grid covering hundreds of square miles of arid terrain in China’s Gansu province. The 119 nearly identical construction sites contain features that mirror those seen at existing launch facilities for China’s arsenal of nuclear-tipped ballistic missiles.

The acquisition of more than 100 new missile silos, if completed, would represent a historic shift for China, a country that is believed to possess a relatively modest stockpile of between 250 and 350 nuclear weapons. The actual number of new missiles intended for those silos is unknown but could be much smaller. China has deployed decoy silos in the past.

During the Cold War, the United States developed a plan to move its ICBMs across a matrix of silos in a kind of nuclear shell game, to ensure that Soviet war planners could never know exactly where the missiles were at any given time.

The construction boom suggests a major effort to bolster the credibility of China’s nuclear deterrent, said researcher Jeffrey Lewis, an expert on China’s nuclear arsenal and part of a team that analyzed the suspicious sites, first spotted by colleague Decker Eveleth as he scoured photos taken by commercial satellites over northwestern China. Lewis described the scale of the building spree as “incredible.”

“If the silos under construction at other sites across China are added to the count, the total comes to about 145 silos under construction,” Lewis, director of the East Asia Nonproliferation Program at the Center for Nonproliferation Studies, part of the Middlebury Institute of International Studies, said in a summary of his findings provided to The Washington Post. “We believe China is expanding its nuclear forces in part to maintain a deterrent that can survive a U.S. first strike in sufficient numbers to defeat U.S. missile defenses.”
