Associated Launch Vehicles
  • CZ-1 Chinese orbital launch vehicle. China began development of the CZ-1 (Changzheng-1 = Long March-1) launch vehicle in the second half of 1965. The project was undertaken with the specific objective of launching China's first satellite, the DFH-1. The CZ-l's first and second stages were adapted from those of the DF-3 intermediate range ballistic missile. The third stage used a new-design solid rocket motor. More...

Associated Propellants
  • Solid Solid propellants have the fuel and oxidiser embedded in a rubbery matrix. They were developed to a high degree of perfection in the United States in the 1950's and 1960's. In Russia, development was slower, due to a lack of technical leadership in the area and rail handling problems. Solid propellants have the fuel and oxidiser embedded in a rubbery matrix.
