The Long March 12 (Chinese: 长征十二号运载火箭), or Chang Zheng 12 as in pinyin, abbreviated LM-12 for export or CZ-12 within China, is a Chinese medium-lift launch vehicle carrier rocket built by the Shanghai Academy of Spaceflight Technology. It is capable of placing at least 12 tonnes of payload in low Earth orbit and at least 6 tonnes in a 700 km Sun-synchronous orbit. Its first launch took place on November 30, 2024 from the Hainan International Commercial Aerospace Launch Site on Hainan island.[1][2]
There is also a planned reusable version of the rocket, the CZ-12A; efforts are currently underway to verify stage-reusability technology via vertical take-off, vertical landing (VTVL) tests.[3]
