DF-11

The Dong-Feng 11 (a.k.a. M-11, CSS-7) is a short-range ballistic missile developed by the People's Republic of China.

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). It entered service with the PLA Second Artillery Corps in 1992.

In 1993, Pakistan purchased the weapon system in secrecy from China but M-11 are capable of delvering 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. 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. Estimates on the number of DF-11s in service vary between 500 and 600. The launch vehicle is made by Wanshan Special Vehicle. A bunker buster variant with improved accuracy called the "DF-11AZT" has also been revealed.
