Associated Launch Vehicles
  • Ariane 2/3 French orbital launch vehicle. Improved version of the Ariane 1. It featured increased thrust first and second stage engines, a 25% stretched third stage, 4 seconds specific impulse improvement in the third stage, a larger internal payload fairing volume, and introduced the Sylda payload carrier for dual payloads. The Ariane 3 version added two solid rocket motor strap-ons. Development was authorised in July 1980 and had a total cost of 144 million 1986 Euros. More...
  • Advanced Scout American all-solid orbital launch vehicle. Proposed upgrade of Scout proposed by the University of Rome with two strap-ons from the Ariane 4. Launch would have been from Italy's San Marco platform off Kenya. Further work cancelled in 1993. 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.
