The Long March 2A, also known as the Chang Zheng 2A, CZ-2A and LM-2A, was a Chinese orbital carrier rocket.
It was launched from Launch Area 2B at the Jiuquan Satellite Launch Centre. It was a 2-stage rocket, and flew 4 times. On its first flight on 5 November 1974, a cable connecting the pitch rate control gyroscope to the guidance system became disconnected, resulting in a loss of control and launch failure.
The rocket was subsequently replaced by the more capable Long March 2C.
The payloads for the Long March 2A were FSW-0 reconnaissance satellites.
