Long March 11
The Long March 11, or Chang Zheng 11 as in pinyin, abbreviated LM-11 for export or CZ-11 within China, is a Chinese four stage solid-propellant carrier rocket of the Long March family, which is developed by the China Aerospace Science and Technology Corporation. It was designed as a "quick reaction" rocket with the ability to launch on short notice, from road vehicles and ships.
Based on a number of design similarities, it is believed the rocket was developed from the DF-31 ICBM, by adding an additional solid propelant 4th stage to the 3 stage missile. This is what gives it its quick launch capabilities, as it can be stored for a longer time than liquid-fueled rockets, and then quickly cold launched from a launch tube, from a sea barge or road mobile vehicle.
The maiden flight of the Long March 11 occurred on 25 September 2015.
The first sea launch occurred on 5 June 2019, from a converted barge stationed in the Yellow Sea. Eighteen launches have been made, six of them from sea.
