China Rocket Co. (CALT)

The China Academy of Launch Vehicle Technology (CALT, 中国运载火箭技术研究院) is China's premier rocket design and manufacturing institution, founded in 1957 under the leadership of Qian Xuesen. A subsidiary of China Aerospace Science and Technology Corporation (CASC), CALT is headquartered in Beijing and employs approximately 33,000 people with total assets exceeding 100 billion yuan.

CALT is the primary developer of the Long March (长征) rocket family — China's workhorse launch vehicles that have carried the majority of Chinese satellites and crewed spacecraft to orbit. The Long March family spans from the small LM-11 (solid, LEO) to the heavy LM-5 (capable of 25 tonnes to LEO) and the human-rated LM-2F/LM-7 used for China's space station program.

Beyond launch vehicles, CALT produces Yuanzheng (远征) upper stages for precise orbit injection, supports China's lunar and deep space exploration programs, and has developed the Feitian extravehicular activity spacesuit. CALT has successfully conducted over 300 Long March launches, achieving a milestone reliability record in the global launch industry.

China Rocket Co., Ltd. is CALT's commercial subsidiary providing international launch services and rideshare opportunities under the Long March brand.
