See what a 3.3 Mt strike from the Dongfeng DF-4 would do to a real city: set ground zero anywhere on Earth and map the fireball, blast, thermal and radiation rings.
The decision to develop the DF-4 was made in 1965 in response to United States ballistic missile submarine patrols operating from Guam. Deployment of the system began in 1975–1976.
The DF-4 is a first-generation two-stage intercontinental ballistic missile utilizing a liquid-fuel propellant system consisting of nitric acid and unsymmetrical dimethylhydrazine. The missile carries a nuclear warhead with a 3.3-megaton yield; the DF-4A variant is capable of carrying three warheads. Guidance is provided by an astro-inertial system, resulting in a circular error probable of 1.5 kilometers.
The People’s Liberation Army Rocket Force is the sole operator of the system. The missile is deployed in two configurations: one housed in underground silos and another stored in caves or garages for roll-out launch. Although initial intelligence estimates projected earlier adoption, limited numbers of missiles were in place by the mid-1980s. The system is positioned to reach targets in Russia, India, and United States bases in the Pacific. The DF-4 remains in service for regional deterrence as it is phased out in favor of the DF-31.
