It is launched from the Jiuquan, Taiyuan Satellite Launch Centre and Xichangs, and consists of 3 stages. Long March 4C vehicles have been used to launch the Yaogan-1, Yaogan-3 SAR satellites and the Fengyun-3A polar orbiting meteorological satellite. On December 15, 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. The Long March 4C is derived from the Long March 4B, but features a restartable upper stage, and a larger payload fairing. On September 1, 2016, the Long March-4C (Chang Zheng-4C) failed for reasons not yet known. A Long March 4C rocket blasted off from the Taiyuan Satellite Launch Centre in Shanxi but failed to insert its payload, the Gaofen-10 satellite, into its designated orbit.[4][5] List of launches{{main|List of Long March launches}}
