A massive military facility is reportedly being developed in China, sparking concerns that Beijing may be building a network of launch pads and bunkers near its nuclear missile sites.
According to satellite images reviewed by Reuters, the facility, located in China's northwestern desert, appears to be an extraordinary effort to safeguard China's land-based nuclear forces.
The images show over 80 sites that could potentially be used by China's growing fleet of mobile missile launchers and air-defence systems.
Security experts warn that the scale of the building work suggests a major expansion of fortified infrastructure, which could be used to support and safeguard China's nuclear forces.
China's 'no first use' policy may be under scrutiny, as some analysts believe the country could use the threat of nuclear force to discourage foreign involvement in any conflict involving Taiwan.
The new infrastructure is focused around two octagon-shaped complexes, with accommodation for personnel, military vehicles, and airfields.
Security experts agree that the facilities could play a big role in supporting China's nuclear programme, while also serving other military functions.
