The Long March 4B (), also known as the Chang Zheng 4B, CZ-4B and LM-4B is a Chinese expendable orbital Launch vehicle. Launched from Launch Complex 1 at the Taiyuan Satellite Launch Center, it is a 3-stage rocket, used mostly to place satellites into low Earth orbit 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.
