SSTW?
Unidentified Chinese satellite. Could this be the mysterious JSSW reconnaissance satellite launched by the FB-1 booster in the 1970's?

Chinese military surveillance satellite. 6 launches, 1973.09.18 (JSSW 1) to 1976.11.10 (JSSW 6). Mysterious early Chinese satellite, orbited by the cancelled FB-1 launch vehicle.

Western opinion was that it was a military photo surveillance satellite, probably using television or radio transmission of scanned film images. Based on American and Soviet experiences with similar systems in the 1960's, the results were probably disappointing.

Gross mass: 1,100 kg (2,400 lb).
First Launch: 1973.09.18.
Last Launch: 1976.11.10.
Number: 6 .

  • CZ China's first ICBM, the DF-5, first flew in 1971. It was a two-stage storable-propellant rocket in the same class as the American Titan, the Russian R-36, or the European Ariane. The DF-5 spawned a long series of Long March ("Chang Zheng") CZ-2, CZ-3, and CZ-4 launch vehicles. These used cryogenic engines for upper stages and liquid-propellant strap-on motors to create a family of 12 Long-March rocket configurations capable of placing up to 9,200 kg into orbit. In 2000 China began development of a new generation of expendable launch vehicles using non-toxic, high-performance propellants with supposedly lower operating costs. However these encountered development delays, and it seemed the reliable Long March series of rockets would continue in operational use for nearly fifty years before being replaced. More...

  • FB-1 Chinese orbital launch vehicle. The FB-1, like the CZ-2 launch vehicle begun the following year, was a two-stage booster developed from the DF-5 intercontinental ballistic missile. Payload for the booster was the JSSW, believed to have been a television-transmission military reconnaissance satellite. The incredible decision to develop two nearly identical rockets concurrently can be blamed on the turbulent factional politics after the Cultural Revolution. More...
