DF-11 (M11 CSS-7)

The Dongfeng (simplified Chinese: 东风; traditional Chinese: 東風; literally: "East Wind") series, typically abbreviated as "DF missiles", are a family of short, medium, intermediate-range and intercontinental ballistic missiles operated by the Chinese People's Liberation Army Rocket Force (formerly the Second Artillery Corps).
The DF-11 (CSS-7, also M-11 for export), is a road-mobile SRBM designed by Wang Zhenhua at the Sanjiang Missile Corporation (also known as the 066 Base) in the late 1970s. Unlike previous Chinese ballistic missiles, the DF-11 use solid fuel, which greatly reduces launch preparation time to around 15–30 minutes, while liquid-fuelled missiles such as the DF-5 require up to 2 hours of pre-launch preparation. The DF-11 has a range of 300 km and 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). Estimates on the number of DF-11s in service vary between 500 and 600.
