The Long March 4B (Chinese: 长征四号乙火箭), 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 launch vehicle, 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 the target in the 2007 Chinese anti-satellite missile test.
The Chang Zheng 4B experienced its only launch failure on 9 December 2013, with the loss of the CBERS-3 satellite.[4]

CBERS-3 | SSO | Failure |
One of the two third-stage engines shut down prematurely, so that the satellite failed to reach orbit. The cause was traced to foreign debris that blocked the engine's fuel intake.[5] | ||||||
