The DF-31 is a Chinese intercontinental ballistic missile (ICBM) developed by the China Aerospace Science and Technology Corporation. It is designed to deliver nuclear warheads over long distances, with an estimated range of about 5,500 to 7,200 kilometers. The missile is road-mobile, allowing for greater flexibility and survivability in a military context. Introduced in the early 2000s, the DF-31 is part of China's strategic nuclear deterrent. It features advanced guidance systems and can carry multiple independently targetable reentry vehicles (MIRVs), enhancing its capability to strike multiple targets simultaneously. The missile plays a crucial role in China's defense strategy.
