Tu-123


Russian intercontinental boost-glide missile. Exotic design for an intercontinental missile using a gas core fission reactor for cruise propulsion. Studied circa 1957.

The Tu-123 was an exotic missile design using an airbreathing kerosene/nuclear mixed propulsion engine. It was proposed as an alternative upper stage on the 'DP' winged rocket system in place of the Tu-130 hypersonic glider. The engine would have given the missile a range in excess of 4000 km (perhaps essentially unlimited, as the American SLAM/Project Pluto) at a speed of 3000 km/hr. Other sources assign the Tu-123 designation to the conventional missile also known as Tu-133.

Standard warhead: 3,000 kg (6,600 lb). Number Standard Warheads: 1. Standard warhead: 205. Boost Propulsion: Kerosene/Nuclear. Maximum speed: 3,000 kph (1,800 mph). Minimum range: 4,000 km (2,400 mi).

  • Soviet Strategic Cruise Missiles As in America, in the 1946 assessments of German military technology, the technical problems of the intercontinental ballistic missile seemed far less than a high-speed cruise missile for the same mission. The Soviet Union developed several such missiles, counterparts to the American Navaho. As in America, it turned out that the ICBM was ready before the cruise missiles were - the navigation and propulsion issues of Mach 3 intercontinental flight were much more difficult than those for Mach 22 ballistic flight. As in America, the projects were cancelled, although they contributed greatly to the national technological base. More...
