The Antonov An-2 (Russian nickname: "Annushka" or "Annie"; "kukuruznik" - corn crop duster; USAF/DoD reporting name Type 22, NATO reporting name Colt.) is a Soviet mass-produced single-engine biplane utility/agricultural aircraft designed and manufactured by the Antonov Design Bureau beginning in 1946.
The An-2 is used as a light utility transport, parachute drop aircraft, agricultural work and many other tasks suited to this large slow-flying biplane. Its slow flight and good short field performance make it suited for short, unimproved fields, and some specialized variants have also been built for cold weather and other extreme environments. The Guinness Book of World Records states that the 45-year production run for the An-2 was for a time the longest ever for any aircraft — and challenging the well over two decades-long run of the much lighter, late-1920s origin Polikarpov Po-2 biplane it was intended to replace — but the An-2's production duration run record was itself recently exceeded by the four-turboprop-engined, 1954-origin Lockheed C-130 Hercules military transport.
The Antonov An-2 was designed to meet a 1947 Soviet Ministry of Forestry requirement for a replacement for the much lighter, largely wooden-airframed Po-2, which was used in large numbers in both agricultural and utility roles. Antonov designed a large single bay biplane of all-metal construction, with an enclosed cockpit and a cabin with room for seats accommodating twelve passengers. The first prototype, designated SKh-1 and powered by a Shvetsov ASh-21 radial engine, flew on 31 August 1947. The second prototype was fitted with a more powerful Shvetsov ASh-62 engine, which allowed the aircraft's payload to be significantly increased from 1,300 to 2,140 kg (2,870 to 4,720 lb), and in this form it was ordered into production.
Initial Soviet production was at State Factory 473 in Kiev, Ukrainian SSR where the bulk of up to 5,000 units had been produced by 1960. Later Soviet production (after 1965, of model An-2M especially) was at State Factory 464 at Dolgoprudniy, Russian SFSR. After 1960, however, most An-2s were built at Poland's WSK factory in Mielec, with over 13,000 made there before full production ended in 1991. Limited production from parts stocks, as well as spares and maintenance coverage continued until 2001, when four aircraft were produced for Vietnam.China also builds the An-2 under licence as the Shijiazhuang Y-5. It has been occasionally and erroneously reported that there was East German production of the An-2. While An-2s were extensively refurbished in East Germany, there were no new aircraft built there.
