30 Jun 2021: Commercial satellite images 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 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. Lewis, along with colleague Decker Eveleth, spotted the construction sites after weeks of scrutinizing commercial satellite photos of northwestern China. He described the scale of the project as “incredible.”

– The reported silo construction project could provide China another means of concealing its most powerful weapons. The construction sites spotted on satellite photos are arrayed in two huge swaths, covering parts of a desert basin stretching to the west and southwest of Yumen, a city of 170,000 people along China’s ancient Silk Road.

– Lewis said the silos are probably intended for a Chinese ICBM known as the DF-41. It can carry multiple warheads and reach targets as far away as 9,300 miles, potentially putting the U.S. mainland within its reach. Major excavation work on the sites began early this year, although preparations were probably underway for months, Lewis said.

– Missile silos are easily spotted by trained imagery analysts, and they are vulnerable to destruction by precision-guided missiles in the early hours of a nuclear war. For those reasons, Lewis sees the silo construction project as part of an expanded deterrent strategy by a country whose nuclear arsenal is dwarfed by those of the United States and Russia, which collectively possess more than 11,000 nuclear warheads.

– Photos of the Gansu construction project were supplied to Lewis and Eveleth by the commercial satellite company Planet, which provided a continuous stream of updated images showing progress at each of the construction sites over time. Based on his analysis, Lewis said, there was “a very good chance that China is planning a shell game” in which it hides a relatively small number of warheads across a network of silos.

Commercial earth observation satellites are increasing in numbers and capabilities. Private analysis firms will continue to expose national security developments that were previously only available to those with access to state-owned space systems. Nearly all commercial earth observation systems in operation today are owned/operated by entities operating from Coalition nations. However, Chinese and Russian companies are in the midst of developing and deploying their own constellations with significant government backing.
