Long March 7

The Long March 7, or Chang Zheng 7 in pinyin, abbreviated LM-7 for export or CZ-7 within China, originally Long March 2F/H or Chang Zheng 2F/H, nicknamed Bingjian, is a Chinese liquid-fuelled launch vehicle of the Long March family, developed by the China Aerospace Science and Technology Corporation (CAST). It made its inaugural flight on 25 June 2016.

Designed as a replacement of the Long March 2F, Long March 7 and its variants was expected to be the workhorse of the fleet, projected to account for around 70% of all Chinese launches. Long March 7 plays a critical role in the Chinese Space Station program: it is used to launch the Tianzhou robotic cargo and resupply spacecrafts to the station. The rocket was intended to replace the Long March 2F as China's crew-rated launch vehicle in the future, although by 2023 this role has apparently been taken over by the under-development Long March 10 and Long March 10A.

Since 2020, in addition to the base Long March 7 configuration, there is the Long March 7A (CZ-7A etc.) variant which differs from the base CZ-7 by the addition of a liquid hydrogen-liquid oxygen third stage inherited from the third stage of the Long March 3B. The rocket has also been developed into the Long March 8.
