The Long March 4C, also known as the Chang Zheng 4C, CZ-4C and LM-4C, previously designated Long March 4B-II, is a Chinese orbital launch vehicle. It is launched from the Jiuquan, Taiyuan, and Xichang Satellite Launch Centers, and consists of 3 stages. All stages use storable (rather than cryogenic) propellants.

The Long March 4C is derived from the 3 stage Long March 4B, but features a restartable third stage, and a larger payload fairing.

Launch summary

[edit]

Long March 4C vehicles have been used to launch the Yaogan-1, Yaogan-3 synthetic-aperture radar (SAR) satellites and the Fengyun-3A polar orbiting meteorological satellite. On 15 December 2009, a Long March 4C was used to launch Yaogan-8.[3]

Because it was still designated as Long March 4B-II at the time of its maiden flight, the first launch is often mistaken for a Long March 4B.

On 1 September 2016, the Long March 4C failed for reasons not yet known. A Long March 4C rocket blasted off from the Taiyuan Satellite Launch Center in Shanxi but failed to insert its payload, the Gaofen 10 satellite, into its designated orbit.[4][5]
