The Antonov An-2 is an extremely durable, light, single-engine biplane which first flew in 31 August 1947 and was the first plane designed by Antonov. It is used as a light transport, capable of carrying 12 passengers, and for parachute drops and agricultural work. Its extraordinary slow-flight and STOL capabilities make it supremely suited for short, unimproved fields, and some specialised variants have also been built for cold weather and other extreme environments.

The An-2 is the largest single-engine biplane ever produced. By 1960 the USSR had produced over 5,000. Since 1960, most An-2s have been built at Poland's WSK factory in Mielec, with over 13,000 made there before full production ended in 1991.
