Sukhoi Su-17

The Sukhoi Su-17, NATO reporting name Fitter, is a variable-sweep wing fighter-bomber developed for the Soviet military from the Su-7. It was the first variable-sweep wing aircraft to enter Soviet service and brought updated avionics. Export versions include the Su-22 and the less common Su-20. The type was produced from 1967 to 1990 and was operated by the Soviet Union and other Warsaw Pact members, countries in the Arab world, Angola and Peru. Although it could carry nuclear weapons, it was used in roles from close air support to ground attack. The most numerous variant was the Su-17M3, with almost 1,000 built, which first flew on 30 June 1976, and the Russian Air Force retired its last Su-17M4 in 1998.
