Long March 3B | ChinaSat 1D

The FH 2 (Feng Huo 2) series are reportedly the second generation of chinese military comsats and data relay satellites. They provide both C-band and UHF communications. China Aerospace Science and Technology Corp. manufactured the satellites based on the DFH-4 Bus. FH-2D is also known as Chinasat-1D.

The Long March 3B / E (G2) (CZ-3B / E) is one of the most successful medium-range launchers and the strongest variant of the CZ-3 series. It was specially developed for the transport of heavy communications satellites into a geostationary transfer orbit. The additional designation "E" stands for a higher payload fairing, stretched boosters and extended fuel tanks at the first stage, over the CZ-3B.

The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
