Long March 2

Long March 2 rocket family or Chang Zheng 2 rocket family as in Chinese pinyin is an expendable launch system operated by the People's Republic of China.

Development and design falls mostly under the auspices of the China Academy of Launch Vehicle Technology (CALT).

However, the Long March 2E had problems with excessive vibration, destroying the Optus B2 and Apstar 2 satellites and damaging AsiaSat 2.

This version is the safest model in the Long March 2 family, with 11 launches and no failure record.

An unmanned derivative called Long March 2F/G carries the bulkier Tiangong space laboratories.
