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 Academy of Launch Vehicle Technology (CALT). It was designed with the ability to launch on short notice and it can launch from road vehicles and ships. It is likely based on the DF-31 missile. The vehicle can be cold launched from a launch tube mounted on a road mobile vehicle.[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] Nine launches have been made as of May 2020.

gollark: I don't think I've ever seen a market-CB egg in a trade.

gollark: Is the market actually very widely used?

gollark: There's one from Egg Drop Soup; I prefer it, because it also tells whether you're locked or not.

gollark: I can never figure out whether I just need to hunt more, pick different biomes or refresh at different times.

gollark: I'm worried about xenowyrms myself.
