The '''Long March 6''' ({{zh|c=长征六号运载火箭}}) or '''Chang Zheng 6''' as in [[Pinyin|pinyin]], abbreviated '''LM 6''' for export or '''CZ 6''' within China, is a Chinese liquid-fuelled [[Engineering:Launch vehicle|launch vehicle]] of the [[Engineering:Long March (rocket family)|Long March family]], which was developed by the [[Company:China Aerospace Science and Technology Corporation|China Aerospace Science and Technology Corporation]] (CASC) <ref>{{cite web |url=http://english.people.com.cn/90001/90776/90881/6748699.html|title=Development of China's new "Changzheng 6" carrier rocket commences|publisher=People's Daily Online|date=2009-09-04|access-date=6 September 2009}}</ref> and the [[Organization:Shanghai Academy of Spaceflight Technology|Shanghai Academy of Spaceflight Technology]] (SAST). The rocket was developed in the 2000s, and made its maiden flight in 2015.<ref name="maidenflight">{{cite web |url=http://www.nasaspaceflight.com/2015/09/china-debut-launch-long-march-6/|title=China conducts debut launch of Long March 6|date=2015-09-19|access-date=20 September 2015}}</ref> 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 [[Engineering:Long March 5|Long March 5]] and the mid-heavy lift [[Engineering:Long March 7|Long March 7]] rocket families. It is capable of placing at least {{cvt|1000|kg}} of payload into a [[Astronomy:Sun-synchronous orbit|Sun-synchronous orbit]].<ref>{{cite web|url=http://www.spaceflight101.com/long-march-6.html|title=Long March 6 - Spaceflight101|access-date=2015-09-20|url-status=dead|archiveurl=https://archive.today/20150918112832/http://www.spaceflight101.com/long-march-6.html|archive-date=18 September 2015}}</ref><ref name="maidenflight"/> The first stage of the Long March 6 was derived from the booster rockets being developed for the [[Engineering:Long March 5|Long March 5]] rocket. It is powered by a YF-100 engine, which generates {{cvt|1340|kN}} of thrust from burning [[Chemistry:Kerosene|kerosene]] and [[Astronomy:LOX|LOX]] as rocket fuel and oxidiser.<ref name="maidenflight"/> This was the first flight of the new engine design.<ref name=News163-20-star/>

An enlarged variant, the [[Engineering:Long March 6A|Long March 6A]], which has four strap-on solid boosters, an elongated stage one, a new stage two with the same diameter as the first stage, and a payload capacity of at least 4000&nbsp;kg to [[Astronomy:Sun-synchronous orbit|Sun-synchronous orbit]], made its maiden flight on 29 March 2022.<ref>{{cite web|url=http://space.skyrocket.de/doc_lau/cz-6.htm|title=CZ-6 (Chang Zheng-6)|website=space.skyrocket.de|access-date=2 November 2017}}</ref>
