Family: Long March. Country: China. Status: Hardware. Other Designations: Long March 3B.
The Long March 3B was the most powerful Long March launch vehicle. It could inject a 5,000 kg payload into geosynchronous transfer orbit. The CZ-3B was developed on the basis of the CZ-3A, but had enlarged propellant tanks, larger fairing, and four boosters strapped onto the core stage. The CZ-3B boosters were identical to those of the CZ-3A.

1998 Jul 18 - - 09:20 GMT. LV Configuration: Chang Zheng 3B no. 5. Launch Site: Xichang . Launch Complex: LC2.
- Sinosat Spacecraft: Spacebus 3000 . Mass: 2,820 kg.
The CZ-3B's liquid hydrogen upper stage and the Sinosat were placed in a 609 x 35958 km x 19.0 deg geostationary transfer orbit at 09:45 GMT. The first two liquid apogee burns were carried out on July 19 and 21. Sinosat, Alcatel Spacebus 3000, was built in Cannes and owned temporarily by EurasSpace, a joint venture between Daimler-Benz Aerospace and the China Aerospace Corporation. After on-orbit testing it was delivered to the Sino Satellite Communications Company of Shanghai for communications services in China. Geostationary at 110.5 degrees E.
