Using images provided by the satellite imaging company Planet, researchers found that China is building 119 silos in the desert of the northwestern province of Gansu.The expansion of the number of launch silos for China’s arsenal of intercontinental range ballistic missiles raises fears that nuclear weapons will become a new issue of contention between Washington and Beijing.

American researchers using commercial satellite imagery say China appears to be significantly expanding the number of launch silos for its arsenal of intercontinental range ballistic missiles, raising fears that nuclear weapons will become a new issue of contention between Washington and Beijing. 

Using images provided by the satellite imaging company Planet, two researchers from the James Martin Center for Nonproliferation Studies (CNS) at the Middlebury Institute of International Studies at Monterey (California) found that China is building 119 silos in the desert of the northwestern province of Gansu. 

Jeffery Lewis, one of the researchers, told VOA that development is likely for China’s DF-41 ICBM, which is believed to be capable of carrying multiple nuclear warheads. With an estimated range of nearly 7,000 kilometers and possible capability to carry up to 10 warheads, researchers believe the missiles can reach targets in the United States.

“We believe China is expanding its nuclear forces in part to maintain a deterrent that can survive a U.S. first strike and retaliate in sufficient numbers to defeat U.S. missile defenses,” Lewis said in a summary of findings provided to VOA

In response to the findings, the State Department said that the U.S. is concerned about China’s rapid expansion of its nuclear capabilities. 

These reports and other developments suggest that the PRC’s nuclear arsenal will grow more quickly, and to a higher level than perhaps previously anticipated,” State Department spokesman Ned Price said in a briefing on Thursday. 

He called the buildup “concerning.” “It raises questions about the PRC’s intent. And for us, it reinforces the importance of pursuing practical measures to reduce nuclear risks,” he continued, “We encourage Beijing to engage with us on practical measures to reduce the risks of destabilizing arms races - potentially destabilizing tensions.”

The Chinese Embassy in Washington did not respond to a request from VOA for comment. 

In 2020, the Department of Defense estimated that China had around 100 ICBMs, and will double that number in the coming years. 

The researchers said the 119 new silos are spread across approximately 1,800 square kilometers near Yumen, a city in Gansu province, with each spaced approximately 3 kilometers apart. Images show that construction began in March 2020, but most building was done since February 2021, “suggesting an extremely rapid pace of construction over the past few months,” the summary said.
