New satellite images analyzed by nuclear arms researchers revealed that China is preparing a second field for up to 110 new missile silos capable of housing nuclear-capable weapons. The discovery adds to another 119 silos discovered earlier this year, and form what researchers described this week as “the most significant expansion of the Chinese nuclear arsenal ever.” Matt Korda and Hans Kristensen, researchers with the Federation of American Scientists (FAS), wrote in a paper published Monday that recent satellite images show China is in the early stages of constructing a new missile silo field about 60 miles southwest of the Chinese city of Hami, in the Xinjiang Province of western China.
