Mi-2 in the photogrammetric version. In the late 1950s, work began in the USSR on a successor to the Mi-1 helicopter. The new helicopter was to carry 8 people and be powered by a turbine engine. At the Klimov design bureau, work began on the GTD-350 engine, modelled on the American Allison 250. The prototype of the V-2 helicopter, powered by two GTD-350 engines, was flown in 1961. In 1963 it entered production under the name Mi-2. In 1964 licensed production of the helicopter and engine was transferred to Poland. The first series-produced examples were manufactured in 1965.
In civil aviation, Mi-2 helicopters continue to be operated for transport, passenger and patrol purposes. They also fly in police aviation. Numerous military versions of the Mi-2 were developed: transport-medical, passenger, training, rescue, chemical reconnaissance and photogrammetric. Based on the Mi-2, the PZL Kania helicopter was developed, powered by Rolls Royce/Allison 250 engines and equipped with Bendix/King avionics, offering significantly improved performance.
The example with side number 2121 was manufactured in December 1971 in the rare photogrammetric version (8 were built), equipped with a Wild RC-8 camera installed in the lower rear section of the fuselage. Mi-2FM 2121 was delivered to the military on 7 February 1972 and served in the 49th Helicopter Regiment (later 49th Combat Helicopter Regiment), 42nd Aviation Squadron, and 1st Aviation Training Centre. It was transferred to the Polish Aviation Museum in 2008.
