A Brief overview of the Long March series
The Long March family of rockets is China’s flagship launch vehicle series that is used to launch most of China’s space missions and satellite launches. It is used by the government run CNSA (China National Space Administration) and the rockets are named after the “Long March” of the Chinese Red Army during the Chinese Civil War 1934–35. They are also called the Changzheng series, labeled “CZ”. (More on China’s Long March series rockets here.)
The Long March 5 and Long March 5B
Also known as the CZ-5, has two main variants, the main variant and the 5B variant. The first flight of the rocket series was originally planned for 2014, but it was pushed back to 2016 after the first production rockets were sent from the port of Tianjin in North China to the Wenchang Space Launch Site on Hainan Island for launch rehearsals on September 20, 2015. On or around August 16, 2016, the final construction and testing of the first CZ-5 rocket to be launched into space was finished at its Tianjin manufacturing site, and the different components of the rocket were sent to the launch location on Hainan island shortly after.
The CZ-5 series can transport up to 14 tonnes of cargo to Geostationary Transfer Orbit (GTO) or roughly 23 tonnes to Low Earth Orbit (LEO) (geosynchronous transfer orbit). It superseded the CZ-2, CZ-3, and CZ-4 series of rockets in service and added additional capabilities that the earlier Long March rocket family lacked. Originally, six CZ-5 variations were planned, but the light variants were dropped in favour of the CZ-6 and CZ-7 family launch vehicles. In 2021, it is announced that a three-core version codenamed CZ-5(DengYue) is being developed for crewed lunar expeditions.
