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.
