The Long March 2A, also known as the Chang Zheng 2A, CZ-2A and LM-2A, was a Chineseorbitalcarrier rocket. It was launched from Launch Area 2B at the Jiuquan Satellite Launch Centre. It was a 2-stage rocket, and flew just once, on 5 November 1974. During this flight, 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.
