Long March 4A

The Long March 4A (Chinese: 长征四号甲火箭), also known as the Changzheng 4A, CZ-4A and LM-4A, sometimes misidentified as the Long March 4 due to the lack of any such designated rocket, was a Chinese orbital carrier rocket. It was launched from Launch Area 7 at the Taiyuan Satellite Launch Center. It was a three-stage rocket, used for two launches in 1988 and 1990. On its maiden flight, on 6 September 1988, it placed the FY-1A weather satellite into orbit. On its second, and final, flight it launched another weather satellite, FY-1B.
