Su-17/22 Fitter



The Sukhoi Su-17 (izdeliye S-32; NATO reporting name: Fitter) is a variable-sweep wing fighter-bomber developed for the Soviet military. Developed from the Sukhoi Su-7, the Su-17 was the first variable-sweep wing aircraft to enter Soviet service and 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.

Development

Shortly after the Su-7 fighter-bomber was put into service, the Sukhoi Design Bureau was ordered to develop a modernization program. The program would be aimed primarily at updating on-board avionics and takeoff/landing characteristics. The concept of variable-geometry wings - something gaining wider attention at that time - was adopted. The program was to be led by Sukhoi's head designer, Nikolay Zyrin.[citation needed]

In 1963, the Sukhoi OKB with input from TsAGI created a variable-sweep wing technology demonstrator. The S-22I (also known as the Su-7IG, NATO designation "Fitter-B"), converted from a production Su-7BM, had fixed inner portions of the wing with movable outer segments that could be swept to 28°, 45°, or 62°.[1] The S-22I first took off (with Vladimir Ilyushin at the controls) on 2 August 1966. It was later demonstrated at the air parade in Domodedovo in July 1967..
