Mikoyan-Gurevich MiG-21UM Mongol-B (256) as used by the East German Air Force at the Luftwaffenmuseum, Berlin-Gatow (Germany)
The Mikoyan-Gurevich MiG-21 (NATO reporting name: Fishbed) is a supersonic jet fighter and interceptor aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. It was popularly nicknamed "Balalaika", from the aircraft's planform-view resemblance to the Russian stringed musical instrument or ołówek (pencil) by Polish pilots due to the shape of its fuselage. Approximately 60 countries over four continents have flown the MiG-21, and it still serves many nations a half-century after its maiden flight. A total of 10.645 aircraft were built in the USSR.
Several MiG-21 trainer versions with two seats (student front and instructor rear) were developed. The MiG-21U that appeared in 1961 was the two-seat training version based on the MiG-21F-13. The MiG-21UM (U = Uchebnyy or "Training" and M = Modernizovannyy or "Modernised") from 1968 referred to by NATO as "Mongol-B" was the two-seat training version of the MiG-21MF but it looks that it retained the "small F intake" but the large tailfin like the MF. Seats are KM-1U for the student and KM-11 for the instructor. The instructor has a foldable periscope at the aft canopy section. Four underwing pylons are possible.
