The Antonov An-2 (Russian nickname: кукуру́зник kukuruznik - a kolkhoz maize worker (inherited from Polikarpov Po-2) also nicknamed Annushka; NATO code name Colt) is an extremely durable, light, single-engine biplane which first flew in 1947. 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 specialized variants have also been built for cold weather and other extreme environments. It is also the world's largest single engine biplane.
