The DF-11 is a modern short range ballistic missile of Chinese origin. It was developed in the late 1980's alongside the larger and more complex DF-15. The DF-11 is also known as the M-11 for export and as the CSS-7 in NATO. The DF-11 also forms the basis for several Pakistani short range ballistic missiles.

The DF-11 can be considered a solid propellant version of the Soviet R-17 Elbrus (SS-1 Scud). The use of solid propellant fuel reduces complexity and crew hazards. Launch preparation is significantly faster as well. The single stage missile has a conventional layout with warhead and guidance section in the nose. The lower section with rocket motor is seperated before re-entry. The four fins in the center are reportedly used for corrections in the terminal phase. The DF-11A is an improved model with increased range due to increased fuel load and adds GPS guidance to the inertial guidance.

The DF-11 can be fitted with various types of warhead. The main types of warhead seem to be a unitary high explosive, submunitions and nuclear with 2/10/20 kT variable yield. The original DF-11 has a maximum range of 280 to 350 km. The DF-11A is believed to have a maximum range of 530 to 600 km. There are also reports of a maximum range of 700 to over 825 km for the DF-11A.

A single DF-11 missile is carried on a highly mobile transporter erector launcher (TEL). Originally the MAZ-543 chassis was used, but the very similar Chinese WS-2400 chassis is most common. These large 8x8 trucks provide good all terrain mobility and may travel over 1.300 km on road per day. Before launch the missile is raised into a vertical position. Emplacement time is 15 to 30 minutes.

The DF-11 and DF-11A are used by China. About 500 to 600 missiles have been produced. The number of TELs is believed to be around 85. The M-11 export version is reportedly used by both Iran and Pakistan. Direct sales are denied by China, but technology transfer to both nations is known to be a fact.
