Mil Mi-22
 Not to be confused with the Airborne Command Post version of the Mil Mi-6.The Mil Mi-22 was a single-engined helicopter project of the 1960s. It was similar in size and shape to the Mil Mi-2 and had problems with planned engine configuration (first W-2 config.). Later schematics interested the Russian military by illustrations of higher-capacity engine configuration 10A GTD-940 kW to be precise (next W-20 config.) and had an improved fuselage unlike the earlier Mil Mi-2.
