History

The PRC began developing the DF-31 ICBM in January 1985. ARMT (then called the 4th Aerospace Academy) was appointed as the main contractor while the research arm of the Second Artillery Corps provided contributing support. The land-based variant of the JL-2 was originally called the DF-23 but was changed later on to the DF-31 because of a change in operational requirements. In 1999, the missile was first displayed publicly at the National Day Parade.The Federation of American Scientists & The Natural Resources Defense Council (DF-31A) Nov, 2006. 73 (PD

/ref> On August 2, 1999, the Chinese state news media reported the successful test of the DF-31. The third test flight of the missile occurred on November 4, 2000; the second test flight had taken place earlier that year. Operational deployment of the missiles reportedly began in 2006. In 2009, US Air Force Intelligence reported that under 15 DF-31 missiles had been deployed.US Air Force Air and Space Intelligence Center, Ballistic and Cruise Missile Threats 200

DF-31A

The PRC has developed an improved variant of the DF-31 called the DF-31A. This upgraded missile has a reported range of 11,200 km, will allow targeting of most of the continental United States and was designed with

DF-31AG/DF-31B

The PRC has developed an improved variant of the DF-31A called the DF-31AG (G stands for 改 (Gaï), "modified) or DF-31B with an off-road 8 axle TEL and

s. China has successfully tested it from a mobile launcher. The missile's TEL features an extra pair of elevators near the aft of the missile unlike the TELs of the DF-31 or DF-31A, suggesting a heavier missile second and third stage than earlier variants. On the military parade marking the 90th Anniversary of the founding of the People’s Liberation Army in 2017, DF-31AG ICBM was officially demonstrated.
