Launch

Long March 12B/Changzheng 12B (LM-12B/CZ-12B) is a reusable orbital launch vehicle developed by the China Aerospace Science and Technology Commercial Launch Vehicle Group (CACL), a subsidiary company of the state-owned China Aerospace Science and Technology Corporation (CASC). The rocket is based on the Long March 12, but extensively re-designed for first stage re-usability, and use of gas generator cycle kerosene/liquid oxygen powered rocket engines in both stages. The first stage uses 9 YF-102R engines and the second stage uses 1 YF-102V engine, both from CASC's Academy of Aerospace Liquid Propulsion Technology (AALPT). On launch missions where the first stage is recovered, it will land on a down-range landing pad located in Minqin County, Gansu Province.

The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
