Associated Engines
  • LR87 LH2 Aerojet lox/lh2 rocket engine. 667 kN. Development ended 1961. Version of the Titan engine, and first large Lox/LH2 engine fired in the world. 52 static tests. But NASA selected Rocketdyne instead to develop the J-2 engine for Saturn from scratch. More...

Associated Launch Vehicles
  • Titan C American orbital launch vehicle. The Titan C, a Titan II booster stage topped by a new liquid oxygen/hydrogen upper stage, was the launch vehicle selected in November 1959 for the DynaSoar orbital flight program. Despite the fact the upper stage engine was secretly tested in 1958-1960, after many political twists and turns, it was cancelled in favor of the Titan 3C in July 1961 More...

Associated Propellants
  • Lox/LH2 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. Liquid hydrogen was identified by all the leading rocket visionaries as the theoretically ideal rocket fuel. It had big drawbacks, however - it was highly cryogenic, and it had a very low density, making for large tanks. The United States mastered hydrogen technology for the highly classified Lockheed CL-400 Suntan reconnaissance aircraft in the mid-1950's. The technology was transferred to the Centaur rocket stage program, and by the mid-1960's the United States was flying the Centaur and Saturn upper stages using the fuel. It was adopted for the core of the space shuttle, and Centaur stages still fly today. More...
