China has built a new research facility to simulate an attack by nuclear bunker-busting weapons and learn how they damage defence facilities, even those built at extreme depths
......
In the past, shelters buried several hundred metres deep were rated nuclear-proof but the Chinese test facility shows that a tunnel more than 2km (1.24 miles) under the surface could be destroyed
......
For instance, the Cheyenne Mountain Complex, home to the North American Aerospace Defence Command, was dubbed by the US military as the “most secure facility in the world” because it was protected by granite above more than 500 metres (1,600 feet) thick.
The Russian government’s doomsday shelter was buried 300 metres deep in the Ural Mountains. West of Beijing, China’s Joint Battle Command Centre, for extra precaution, was built in natural karst caves about 2km underground.
Openly available information suggests most ground-penetrating weapons could not reach a depth beyond 40 metres (130 feet).
But with the recent rapid development of technology, existing safety standards may be outdated and have “severely underestimated the actual impact” of nuclear weapons, said Li Jie, lead project scientist with the Army Engineering University of PLA in Nanjing, Jiangsu province, in a paper published in the peer-reviewed Chinese Journal of Rock Mechanics and Engineering last week.
According to some calculations by Chinese researchers based on underground nuclear testing data and computer simulation, the destruction caused by a nuclear bunker buster using the latest technology could reach three to 10 times deeper underground than previously thought.
