Long March 2C (LM-2C), or Chang Zheng 2C (CZ-2C) as in Chinese pinyin is a member of the Long March 2 rocket family, an expendable launch system operated by the People's Republic of China. This vehicle was developed by the China Academy of Launch Vehicle Technology, and the first launch occurred on September 9, 1982. It is a two-stage launch vehicle with storable propellants, consisting of Nitrogen Tetroxide and Unsymmetrical Dimethyl Hydrazine. The rocket was derived from the Long March 2A launch vehicle.

Several variants of this launch vehicle have been built, all using an optional third solid motor stage:^[2]

2C/SD — Commercial satellite launcher with a multi-satellite smart dispenser allowing delivery of two satellites simultaneously
2C/SM — Version for delivery of small satellites to high orbits
2C/SMA — Improved version of the 2C/SM

Launch failures

Shijian 11-04 launch failure

On August 18, 2011, a Long March 2C rocket failed during the launch of the Shijian 11-04 satellite. During the powered flight phase of the second stage, the connecting mechanism between vernier engine no.3 and the servo-control mechanism of the second stage failed, which lead to loss of attitude control on the second stage.^[3]
