The Sukhoi Su-17 (izdeliye S-32) is a variable-sweep wing fighter-bomber developed for the Soviet military. Its NATO reporting name is Fitter. Developed from the Sukhoi Su-7, the Su-17 was the first variable-sweep wing aircraft to enter Soviet service and was featured updated avionics. The aircraft also has variants which were designed to be exported to non-Soviet states such as the Sukhoi Su-22 and the less popular Su-20.

It was produced from 1967-1990. The Su-17/20/22 series had a long career and has been operated by many air forces, including those of the Russian Federation, former Soviet republics, former Warsaw Pact, countries in the Arab world, Angola, and Peru. The Russian Federation retired its fleet in 1998.

Although the Su-17 was capable of carrying nuclear weapons, it was used in roles ranging from close-air support to ground attack.
