DF-3A: History, Applications & Measurement

The DF-3A (NATO: CSS-2) is a Chinese liquid-fueled, single-stage, nuclear-capable intermediate-range ballistic missile. It entered service with the People's Liberation Army Rocket Force in 1971, and its units were fully converted to the DF-21 by 2014. The missile was used as the basis for China's first launch vehicle, the Long March 1.
