The AN-22 made its first flight from Svyatoshin airfield in February 1965. A total of 66 AN-22 aircraft, including AN-22A variants, were produced by January 1976. The aircraft has a wide cargo compartment with a volume of 638.8m3 to accommodate oversized cargoes.
The turboprop-powered aircraft is equipped with four Kuznetsov NK-12MA turboprops driving four contra-rotating propellers. The power-plant provides a maximum speed of 740km/h and a range of 5,250km.
The Y-20, developed by Xi'an Aircraft Industrial Corporation (Xian) for the People's Liberation Army Air Force (PLAAF), is the biggest indigenous strategic airlifter ever built in China. The aircraft has a maximum take-off weight of 220t and can carry a payload of 60t.
The Y-20 project was launched in 2006 and the first prototype made its maiden flight in January 2013. The aircraft is expected to enter into service with the PLAAF by 2017.
The aircraft features rear cargo-loading system and retractable landing gear. The power plant of the Y-20 prototypes consists of four D-30KP-2 or WS-18 turbofan engines, whereas the production aircraft is expected to be equipped with WS-20 engines.
