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...

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.
