systemInertial and celestial guidance The Dong Feng 4 (Chinese: 东风4) or DF-4 (also known as the CSS-3) is a two-stage Chinese Intercontinental ballistic missile[8] with liquid fuel (Nitric acid/UDMH). It was thought to be deployed in limited numbers in underground silos beginning in the 1970s and early 1980s. The Dong Feng 4 has a takeoff thrust of 1,224.00 kN, a takeoff weight of 82000 kg, a diameter of 2.25 m, a length of 28.05 m and a fin span of 2.74 m. The range of the Dong Feng 4, which is equipped with a 2,190 kg nuclear warhead with 3.3 Mt yield, with a nominal range of 5,500 km. The missile uses an inertial guidance system, resulting in a CEP of 1,500 meters.

History
The decision to develop the DF-4 was made in 1965[9] in response to the U.S. ballistic missile submarine patrols that began operating out of Guam. The missile's designer has been variously identified as Ren Xinmin or Tu Shou'e [屠守锷], and it was produced at Factory 211 (Capital Astronautics Co. [首都航天机械公司], also known as Capital Machine Shop [首都机械厂]).
In 1972 US intelligence estimated an IOC for this system as being expected in 1974 or 1975. Deployment actually began in 1975-76, but only four DF-4s were believed to be in place by 1984.[10]
There were two versions of the missile developed,[11] one version housed in caves or garages to be rolled out on launch and another silo based version.
The U.S. DoD estimates that the missile will continue to serve as a regional deterrence instrument until they can be replaced by the DF-31.[12]
