The Underground Great Wall of China is a vast network of tunnels located in China, designed for the storage and transport of intercontinental ballistic missiles (ICBMs). This strategic military infrastructure spans approximately 3,000 miles (5,000 kilometers) and serves as a critical component of China's national defense system. The tunnels are part of a broader effort to enhance the country's military capabilities and ensure the secure deployment of its nuclear arsenal.
While the exact locations of these tunnels are not publicly disclosed, they are believed to be strategically distributed across the country to maximize operational effectiveness and survivability.
