|Banshee American intercontinental cruise missile. Cruise missile version of B-29 bomber|
|Navaho The Navaho intercontinental cruise missile project was begun just after World War II, at a time when the US Army Air Force considered ballistic missiles to be technically impractical. The Navaho required a large liquid propellant rocket engine to get its Mach 3 ramjet up to ignition speed. This engine, derived with German assistance from that of the V-2, provided the basis for the rockets that would later take Americans into space.
It turned out that mastering the guidance and materials technology needed for a Mach 3 cruise air vehicle was actually more difficult than for a Mach 22 ballistic missile. In the end, the Redstone, Thor, Jupiter, and Atlas rockets were flying before their equivalent-range Navaho counterparts. However the Navaho program provided the engine technology that allowed the US to develop these ballistic missiles rapidly and catch up with the Russians. Navaho also developed chem-milling fuel tank fabrication techniques, inertial and stellar navigation, and a host of other technologies used in later space vehicles. It put North American Aviation, and its Rocketdyne Division, in a leading position that allowed them to capture the prime contracts for the X-15, Apollo, and Space Shuttle projects, thereby dominating American manned spaceflight for the next seventy years.
|Navaho G-38 American intercontinental cruise missile. The intercontinental-range Navaho G-38 was the ultimate development of the German A-9/A-10 concept. At the time the Navaho program was cancelled on 13 July 1957 missiles were in fabrication with first flight test planned by the end of 1958.|
|MX-775 American intercontinental cruise missile.|
|MKR Russian intercontinental cruise missile. A wide range of MKR (intercontinental winged missiles) were studied in 1957-1960 in accordance with a decree of the General Staff. The trade-off studies encompassed long-range air-breathing aircraft, winged rockets, and aircraft launchers for air-breathing missiles.|
|Snark American intercontinental subsonic cruise missile. Developed 1946-1959; deployed only briefly in 1961 before being made obsolete by ICBM's. The control and navigation technology developed for it during the 1950's provided the basis for later Northrop navigation systems used in strategic ballistic missiles.|
|Burya La-350 A government decree on 20 May 1954 authorized the Lavochkin aircraft design bureau to proceed with full-scale development of the Burya trisonic intercontinental cruise missile. Burya launches began in July 1957. The project was cancelled, but the team was allowed final tests in 1961 that demonstrated a 6,500 km range at Mach 3.2 with the 2,350 kg payload. In cancelling Burya the Russians gave up technology that Lavochkin planned to evolve into a manned shuttle-like recoverable launch vehicle.|
|Boojum Intercontinental supersonic cruise missile. A follow-on to the Snark that was Northrop's competitor with the North American Navaho. Never reached development stage and no details available. Name obviously derived from the punch line of Lewis Carroll's poem: "...for the Snark was a Boojum, you see..."|
|M-51 Russian intercontinental cruise missile. Intercontinental cruise missile based on M-50 manned bomber. Subsonic cruise with Mach 2 dash into the target area.|
|Tu-133 Russian intercontinental cruise missile. Mach 3 intercontinental range cruise missile, cancelled in 1960 before flight tests began.|
|P-100 Russian intercontinental cruise missile. Family of sea- or silo- launched Mach 3.5 cruise missiles with ranges up to intercontinental distances.|
|SLAM American intercontinental Mach-3-at-sea-level cruise missile, powered by a nuclear ramjet. Development begun 1957. Cancelled 1964 over cost and environmental concerns.|
