The Long March 11 (Chinese: 長征十一號運載火箭), or Chang Zheng 11 as in pinyin, abbreviated LM-11 for export or CZ-11 within China (and designated 11H when launched from sea), 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 with the ability to launch on short notice and it can launch from road vehicles (CZ-11) and ships (CZ-11H). Sometimes the rocket is thought to be likely based on the DF-31 missile, which is actually not true. The vehicle can be cold launched from a launch tube mounted on a road mobile vehicle.[1][2]
The maiden flight of the Long March 11 occurred on 25 September 2015.[3]
The first sea launch occurred on 5 June 2019, from a converted barge stationed in the Yellow Sea.[4] Seventeen launches have been made as of December 2023[update], five of them from sea.
