The DF-100 is a supersonic strategic cruise missile (weapon system) developed by the People's Republic of China, also known as the Chang Jian 100 (CJ-100). It is a key component of China's growing arsenal of advanced missile systems. The missile was reportedly debuted in 2019 and achieved full operational deployment by 2022. It was created to provide a precision strike capability with extended range and high speed, specifically designed to destroy ground and sea targets.
The missile is a land-based, long-range system powered by a ramjet engine with a solid rocket booster. Its operation involves a three-stage flight profile: an initial boost phase, a high-altitude cruise phase at 30 to 40 km, and a terminal glide phase. The DF-100 maintains a sustained flight speed of Mach 4 and can achieve speeds of Mach 5 during its terminal phase, which involves high-speed maneuvering to evade defenses. Its operational range is reported to be between 3,000 and 4,000 km, an increase from initial reports of 2,000 to 3,000 km. The missile carries a payload exceeding 500 kg and can be equipped with either conventional or nuclear warheads.
The DF-100 is a critical element in China's Anti-Access/Area Denial (A2/AD) strategy, which aims to challenge existing missile defense systems by reducing interception response times. It is part of the broader Dong Feng (DF) missile series and connects to the concept of supersonic cruise missiles, such as the Indo-Russian BrahMos.
