Launch Complex 1, also known as Pad 1, is a Long March launch complex at the Taiyuan Satellite Launch Centre. It consists of a single launch pad, which has been used by Long March 2C, Long March 4A, Long March 4B and Long March 4C carrier rockets. Until the activation of Launch Complex 2 in 2008, it was the only launch site for Long March 4 rockets. Long March 4 launches have since also occurred from Jiuquan.
