Long March 10 (LM-10; Chinese: 长征十号; pinyin: Chángzhēng Shíhào) or Changzheng 10 (CZ-10) is a family of three rockets under development by the China Academy of Launch Vehicle Technology for crewed lunar missions, flights to the Tiangong space station, and commercial launches.
The standard Long March 10 is a three-stage super heavy-lift rocket with a core and two boosters of a common design: a five-meter-wide kerolox-fuelled stage powered by seven YF-100K engines. It is designed to launch a single Mengzhou crewed orbiter or Lanyue lander, with a trans-lunar injection (TLI) burn from its hydrolox third stage of three YF-75E engines. It has a payload capacity of 70 tonnes (150,000 lb) to low Earth orbit (LEO) and at least 27 tonnes (60,000 lb) to TLI.
The Long March 10A and Long March 10B are medium-lift variants, omitting the boosters and third stage; their first stage is designed for recovery and reuse via vertical landing on a floating platform. The CZ-10A is designed for crew and cargo transport to Tiangong, superseding the Long March 2F and Long March 7 respectively, with a capacity of at least 14 tonnes (31,000 lb) to LEO. The CZ-10B is a commercial launch variant of the Long March 10A, with a methalox second stage, increasing its LEO capacity to at least 16 tonnes (35,000 lb).
In February 2026, a CZ-10 first stage booster launched from Wenchang Space Launch Site and performed a controlled splashdown 200 metres (660 ft) from its landing platform in the South China Sea. In July, the maiden CZ-10B launch achieved orbit and a first stage platform landing. The CZ-10A maiden orbital flight, carrying Mengzhou 1, is planned for late 2026; crewed lunar missions are planned culminating in a landing by 2030, after which the much larger Long March 9 is planned to replace it in the super-heavy lift role.
