It was designed with the ability to launch on short notice and it can launch from road vehicles (CZ-11) and ships (CZ-11H). The vehicle can be cold launched from a launch tube mounted on a 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. Seventeen launches have been made, five of them from sea.
