The Long March 2E, also known as the Chang Zheng 2E, CZ-2E and LM-2E, was a Chineseorbitalcarrier rocket. Designed to launch commercial communications satellites, the Long March 2E was retired in favour of the Long March 3B, after two launch failures. Launched from complex 2 at the Xichang Satellite Launch Centre, it is a three-stage carrier rocket. The Long March 2E made its maiden flight on 16 July 1990, and was retired on 28 December 1995. It forms the basis of the Long March 2F, used to launch manned Shenzhou missions. The booster rockets have also been reused on the Long March 3B and Long March 3C.
