The Raduga Kh-20 (NATO reporting name: AS-3 Kangaroo) was an air launched cruise missile armed with a thermonuclear warhead which was developed by the Soviet Union during the Cold War.
==Background== Kh-20 cruise missile was designed by M.I. Gurevich for the Tu-95 strategic bomber. Development began in 1954, drawing on experience with MiG-17 and MiG-19 fighters. Two Tu-95 were converted to Tu-95K missile carriers in 1955. Initial testing of the missile systems was performed using four specially modified MiG-19 fighters designated SM-20/I and SM-20/II for mothership-missile interface and airborne launch testing, and SM-K/I and SM-K/II for guidance system and ground launch testing. First SM-20/I launch from Tu-95K was made in the fall of 1956. One of the greatest challenges in the early development was starting the missile's Lyulka AL-7F turbojet engine after prolonged flight in the very cold upper atmosphere. Kh-20 began flight testing on March 17, 1958. thumb|A Kh-20 missile on display.The first launch was unsuccessful and range and accuracy did not meet expectations. This was in part because the warhead and the guidance system weight exceeded projected limits. Government trials took place between October 15, 1958, and November 1, 1959, and consisted of 16 launches of which 11 were considered successful although accuracy still left much to be desired. Kh-20 entered service in 1960. The production version, designated Kh-20M, featured an improved nuclear warhead. The arsenal initially consisted of two Kh-20 per Tu-95K, which amounted to 130 missiles for approximately 40 Tu-95K and 25 Tu-95KD. This number was later reduced to one missile per aircraft.
