The Long March 6 (Chinese: 长征六号运载火箭) or Chang Zheng 6 as in pinyin, abbreviated LM-6 for export or CZ-6 within China, is a Chinese liquid-fuelled carrier rocket of the Long March family, which was developed by the China Aerospace Science and Technology Corporation[7] and the Shanghai Academy of Spaceflight Technology. The rocket was developed in the 2000s, and made its maiden flight in 2015.[8] As one of the new generation rocket family, the Long March 6 was designed to be a light capacity, "high-speed response" rocket, complementing the heavy lift Long March 5 and the mid-heavy lift Long March 7 rocket families. It is capable of placing at least 1,000 kilograms (2,200 lb) of payload into a sun-synchronous orbit.[9][8] The first stage of the Long March 6 was derived from the booster rockets being developed for the Long March 5 rocket. It is powered by a YF-100 engine, which generates 1,340 kilonewtons or 300,000 pounds-force of thrust from burning kerosene and LOX as rocket fuel and oxidiser.[8] This was the first flight of the new engine design.[3]

A boosted variant, with a payload of 4 tons to sun-synchronous orbit, is under development.
