History

The DF-11 is a road-mobile short-range ballistic missile (SRBM) which began development in 1984 as the M-11, of which was led by the China Sanjiang Space Group (previously known as Base 066).^[5] It entered service with the PLA Second Artillery Corps in 1992.^[6]

In 1993, Pakistan purchased the weapon system in secrecy from China but M-11 are capable of delivering conventional ammunition not nuclear capable.

Description

The DF-11 has range of 300 km with an 800 kg payload. An improved DF-11A version has increased range of >825 km.^[7] The range of the M-11 does not violate the limits set by the Missile Technology Control Regime (MTCR). Unlike previous Chinese ballistic missiles, the DF-11 use solid fuel, which greatly reduces launch preparation time (15-30 min). Liquid-fueled missiles such as the DF-5 require up to 2 hours of pre-launch preparation. The upgraded DF-11B has been revealed as well.^[8] Estimates on the number of DF-11s in service vary between 500 and 600.^[9][10] The launch vehicle is made by Wanshan Special Vehicle. A bunker-buster^[11] variant with improved accuracy called the "DF-11AZT" has also been revealed.^[12]
