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 [[Physics:Orbit|orbit]]al [[Engineering:Launch vehicle|launch vehicle]]. It is launched from the Jiuquan, Taiyuan, and Xichang Satellite Launch Centers, and consists of 3 stages. Long March 4C vehicles have been used to launch the [[Engineering:Yaogan|Yaogan-1]], [[Engineering:Yaogan|Yaogan-3]] [[Engineering:Synthetic-aperture radar|synthetic-aperture radar]] (SAR) satellites and the Fengyun-3A polar orbiting [[Engineering:Weather satellite|meteorological satellite]]. On 15 December 2009, a Long March 4C was used to launch [[Engineering:Yaogan|Yaogan-8]].<ref>{{cite web|url=http://www.nasaspaceflight.com/2009/12/china-completes-2009-schedule-by-launching-another-spy-satellite/|title=China completes 2009 schedule by launching another spy satellite|author=Rui C. Barbosa|publisher=NASASpaceFlight.com|date=15 December 2009}}</ref>

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 [[Engineering:Long March 4B|Long March 4B]]. The Long March 4C is derived from the Long March 4B, but features a restartable [[Astronomy:Multistage rocket|upper stage]], and a larger payload fairing.

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 [[Engineering:Gaofen (satellite)|Gaofen 10]] satellite, into its designated orbit.<ref name="Gaofen 10">{{cite web|url=http://www.scmp.com/news/china/article/2012919/chinese-rocket-launch-reported-have-failed-destroying-earth-observing|title=Chinese rocket launch reported to have failed, destroying cutting-edge earth observation satellite|author=Stephen Chen|newspaper=South China Morning Post|date=2 September 2016|access-date=2 September 2016}}</ref><ref>{{cite web|url=https://www.nasaspaceflight.com/2016/09/long-march-4c-apparently-fails-during-gaofen-10-launch/|title=Long March 4C apparently fails during Gaofen 10 launch |author=Rui C.
