Associated Launch Vehicles
  • Saenger German sled-launched intercontinental boost-glide missile. Saenger-Bredt antipodal bomber - sled launched, boosted to suborbital velocity, 'skips' off upper atmosphere to deliver bombload on target, recovery back at launch site. Fascinated Stalin, led to US Dynasoar project. More...

Associated Propellants
  • Lox/Alcohol Liquid oxygen was the earliest, cheapest, safest, and eventually the preferred oxidiser for large space launchers. Its main drawback is that it is moderately cryogenic, and therefore not suitable for military uses where storage of the fuelled missile and quick launch are required. Alcohol (C2H5OH) was the fuel used for the German V-2 rocket, and the first derivative rocket engines in the United States, Soviet Union, and China used it as well. Better performance was achieved by increasing the alcohol concentration in the post-war engines. But after better-performance rocket-grade kerosene was developed by Rocketdyne in the REAP program of 1953, use of alcohol was abandoned. More...
