The Long March 12 carrier rocket (Chinese: 长征十二号运载火箭), is a Chinese medium-lift launch vehicle currently under development. It will be capable of placing at least 10 tonnes of payload in low Earth orbit and at least 6 tonnes in a 700 km Sun-synchronous orbit. Its first launch is planned to take place in 2024 from the commercial pads at the Wenchang Space Launch Site.[1]
Overview
On 26 February 2024, the China Aerospace Science and Technology Corporation (CASC) released its annual "Blue Book" which detailed the company's launch plans for the coming year; one of the projects revealed in the Blue Book is the new Long March 12 medium-lift rocket.[1] Long March 12 (CZ-12) is designed as a two-stage rocket: its first stage will be powered by four YF-100k 1250 KN engines using RP-1 and liquid oxygen while its second stage will be powered by two YF-115 180 kN engines also using RP-1/LOX. The rocket offers two payload fairing choices, one with a diameter of 5.2 metres and another with a diameter of 4.2 metres.[2]
CZ-12 has a stage diameter of 3.8 metres, a first for China. It will be launched from the new commercial launch site located at China's coastal spaceport in Wenchang.[3]
