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.

gollark: Presumably they just have a way for developers to "submit" "games" and it's not human-verified.
gollark: I think that the rickroll thing there is a "game" on the store, which you can "gift".
