Hidden complexes are revealed in satellite images.
China is actively building hidden nuclear complexes in remote mountain valleys in the southwestern province of Sichuan. This is according to The New York Times, citing satellite images.
One of the key sites that has attracted the attention of journalists and experts is the Jitong Valley, where Chinese engineers are building new bunkers and protective ramparts. Satellite data shows numerous pipes indicating work with highly hazardous materials - it is likely that conventional explosives used as detonators in nuclear warheads are made there.
Another facility, Pingtong, surrounded by a double fence, specializes in the production of nuclear warheads with plutonium. The central structure with a 117-meter-high vent has recently been renovated: new vents and heat diffusers have been added. Active construction continues nearby, and a giant inscription of the words of China's leader Si Jinping can be seen above the entrance: "Stay true to the fundamental cause and always remember our mission." This call, visible from space, symbolizes the ideological basis for nuclear expansion.
The complexes are just part of a network of secret facilities created back in the 1960s under Mao Zedong's "Third Front" project. Back then, tens of thousands of scientists were cutting laboratories in the mountains to protect the nuclear program from U.S. or Soviet strikes. After the détente of the 1980s, many were downsized, but modernization has accelerated since 2019.
"The changes we see at these facilities are in line with China's broader goals of becoming a global superpower. Nuclear weapons are an integral part of that," notes Renny Babiarz, a geospatial intelligence expert.
The Pentagon estimates that China already has more than 600 warheads and plans to double that number by 2030. While this is smaller than the arsenals of the United States or Russia, the growth is alarming in Washington. Deputy Secretary of State Thomas G. Di Nanno has accused Beijing of secret nuclear tests that violate a global moratorium.
"China wants to be in a position where it believes it is largely immune from nuclear pressure from the United States," commented Michael S. Chase of the RAND Corporation.
