The Antonov An-22 "Antei" (, ''An-22 Antej''; English '' Antaeus'') (NATO reporting name "Cock") is a heavy military transport aircraft designed by the Antonov Design Bureau in the Soviet Union. Powered by four turboprop engines each driving a pair of contra-rotating propellers, the design was the first wide-body transport aircraft and remains the world's largest turboprop-powered aircraft to date. The An-22 first appeared publicly outside the Soviet Union at the 1965 Paris Air Show. Thereafter, the model saw extensive use in major military and humanitarian

Design and development

In the late 1950s, the Soviet Union required a large military transport aircraft to supplement the Antonov An-8 and An-12s then entering service. Originally known as the An-20, the model is a conventional multi-engined high-wing design. In the early 1960s, the Antonov bureau produced a wooden mock up at its Kyiv, Ukraine, workshops of what was designated the Model 100. The prototype, now designated the An-22, was rolled out on 18 August 1964 and first flew on 27 February 1965. The prototype was given the name Antaeus (sometimes misspelled Antheus) and, after four-months of test flying, was displayed at the 1965 Paris Air Show. All aircraft were built at the Tashkent State Aircraft Factory and the first military delivery was made to the Air Transport Wing at Ivanovo Airbase in 1969. The aircraft was designed as a

. It has the capability to takeoff from austere, unpaved, and short airstrips, allowing airborne troops to perform air-landing operations. This is achieved by four pairs of contra-rotating propellers, similar to those on the Tupolev Tu-114. The propellers and exhaust from the engines produce a slipstream over the wings and large double-slotted flaps. The landing gear is ruggedized for rough airstrips. In early versions tire pressures could be adjusted in flight for optimum landing performance. That feature was removed in later models. The An-22 follows traditional cargo transport design with a high-mounted wing allowing a large cargo space of 33 m in length and a usable volume of 639 m³. The forward fuselage is fully pressurized and provides space for 5 to 8 crew and up to 28 passengers, but the cargo space is pressurized to only 3.55 PSI / 0.245 bar allowing for a lighter airframe. A door equipped with pressure bulkhead is located at frame 14, separating the cargo attendant's compartment from the main cargo compartment. This allows the rear cargo doors to be opened during flight for paratroops and equipment drop. Like the An-12, the aircraft has a circular fuselage section. The An-22 has set a number of payload and payload-to-height world records. The An-22 has the general appearance of an enlarged version of the earlier

except that it is fitted with a twin tail. This gives the An-22 better engine-out performance, and reduces height restrictions for hangars. Also of note are large anti-flutter masses on the top of each tail. Only one production variant was built, the standard An-22. Prototypes, such as the one first featured at the

Paris Air Show had fully glazed noses that lacked the nose-mounted radar of production models. Those aircraft had the radar mounted below the right wheel well fairing, forward of the wheels. Antonov designated a variant with a modified electrical system and an additional augmented flight control system the An-22A but the designation was not used by the military. A proposed civil airliner version capable of seating 724 passengers on upper and lower decks was planned but wasn't constructed. (For comparison, a typical

, but these are slowly being replaced by the bigger turbofan-powered Antonov An-124. The remaining An-22s appear to be operated by an independent military transport aviation squadron at Migalovo base in Tver. As of December 2018, six An-22s were in service with the 76th Military Transport Air Squadron at Tver, with only three aircraft airworthy. They are planned to remain in service until 2033. A single An-22 (registration number UR-09307) is in service with Antonov Airlines as of September 26, 2020 but was potentially damaged in 2022 during Russia's military action in Ukraine.
