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 orbital carrier rocket. 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 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.

The Chang Zheng 4B experienced its only launch failure on 9 December 2013, with the loss of the CBERS-3 satellite.[4]

gollark: Membrane, I think.

gollark: It lacks function keys, unlike my laptop somehow.

gollark: My brother is very gamer and has a mechanical keyboard.

gollark: Yes. Those who deny this are to "1v1" me in Factorio.
