The DF-3A is a Chinese liquid-fueled, single-stage, medium-range nuclear ballistic missile that entered service in 1971. DF-3A is the oldest missile in China's inventory and is nearing retirement after four decades of service.
It is currently being retired and was inaccurately predicted to have been removed from China's missile arsenal in 2002. In 1987 China sold several dozen (reportedly between 36 and 60) outmoded DF-3 missiles to Saudi Arabia, minus their nuclear warheads.
