Later Soviet production (after 1965, of model An-2M especially) was at State Factory 464 at Dolgoprudniy, Russian SFSR. Initial Soviet production was at State Factory 473 in Kyiv, Ukrainian SSR, where the bulk of up to 5,000 units had been produced by 1960. On the static display of 'Oldtimer Fliegertreffen' Hahnweide 2011 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. The first prototype, designated SKh-1 and powered by a Shvetsov ASh-21 radial engine, flew on 31 August 1947.

Antonov designed a large single bay biplane of all-metal construction, with an enclosed cockpit and a cabin with seats for twelve passengers. The Antonov An-2 was designed to meet a 1940s Soviet Ministry of Forestry requirement for a replacement for the much lighter, largely wooden-airframed Polikarpov Po-2, which was used in large numbers in both agricultural and utility roles. All versions (other than the An-3 and the An-2-100) are powered by a 750 kW (1,010 hp) nine-cylinder Shvetsov ASh-62 radial engine, which was developed from the Wright R-1820. The most common version is the An-2T 12-seater passenger aircraft.

The An-2 was designed as a utility aircraft for use in forestry and agriculture, but the basic airframe is highly adaptable and numerous variants of the type have been developed these include hopper-equipped versions for crop-dusting, scientific versions for atmospheric sampling, water-bombers for fighting forest-fires, flying ambulances, float-equipped seaplane versions and lightly armed combat versions for dropping paratroops. The An-2 was produced up to 2001 and remains in service with military and civilian operators around the world. Its durability, high lifting power, and ability to take off and land from poor runways have given it a long service life. The Antonov An-2 ('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 1947. Series production may still continue in China as the Shijiazhuang Y-5 engine refitting project began in 2013
