Launched from Launch Complex 1 at the Taiyuan Satellite Launch Centre, it is a 3-stage rocket, used mostly to place satellites into low Earth and sun synchronous orbits. It was first launched on 10 May 1999, with the FY-1C weather satellite, which would later be used in the 2007 Chinese anti-satellite missile test.
