The Raduga KSR-5/NATO: AS-6 KINGFISH is a large Russian/Soviet air-to-surface missile, launched from long-range aircraft such as the Tu-22M/NATO: BACKFIRE. It may have a nuclear or conventional warhead. The mass and speed of the missile, combined with conventional explosives, make it a much greater threat against ships, for example, than the smaller AGM-84 Harpoon or Exocet anti-shipping missiles.
The missile flies at supersonic speed (Mach 3.5 range), and high altitude (est. 65,000 feet/20 KM). While it is not believed to use evasive maneuvering, it flies above the range of many small surface-to-air missiles. Its final approach is as a high-speed dive.
