About Long March 12B
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.
