The Long March 3A (Chinese: 长征三号甲火箭), also known as the Chang Zheng 3A, CZ-3A and LM-3A, is a Chinese orbital carrier rocket design. It is a 3-stage rocket, and is usually used to place communications satellites and Beidou navigation satellites into geosynchronous transfer orbits.

It has formed the basis of the Long March 3B, which is a heavier version with four liquid booster rockets.

Launches

Long March 3A rockets have been launched from Launch Areas 2 and 3 at the Xichang Satellite Launch Center.
