Associated Launch Vehicles
  • Buran Russian intercontinental cruise missile. A government decree on 20 May 1954 authorised the Myasishchev aircraft design bureau to proceed with full-scale development of the Buran trisonic intercontinental cruise missile. The competing Burya design of Lavochkin was launched in July 1957, but the development of unstoppable ICBM's had made intercontinntal cruise missiles oboslete. The equivalent American Navaho project was cancelled ten days later. Korolev's R-7 ICBM completed its first successful test flight in August. Buran was being prepared for its first flight when Myasishchev's project was cancelled on November 1957. More...

Associated Propellants
  • Air/Kerosene Ambient air (78 % nitrogen, 21% oxygen, etc.) is scooped up by air intakes and used in turbojet, turbofan, ramjet, scramjet, or other airbreathing engines. It is used to burn aviation-grade kerosene, commercial grade JP-4 or JP-5, their military equivalents, or special high-temperature blends such as those used in the SR-71. More...
