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.\r\n\r\nThe 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).\r\n\r\nOn launch missions where the first stage is recovered, it will land on a down-range landing pad located in Minqin County, Gansu Province.","family":"Long March","full_name":"Long March 12B","manufacturer":{"id":88,"url":"https://ll.thespacedevs.com/2.0.0/agencies/88/?format=json","name":"China Aerospace Science and Technology Corporation","featured":true,"type":"Government","country_code":"CHN","abbrev":"CASC","description":"The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program.
