Sukhoi Su-7
The Sukhoi Su-7 was a swept wing, supersonic fighter aircraft developed by the Soviet Union in 1955. Originally, it was designed as tactical, low-level dogfighter, but was not successful in this role. On the other hand, soon-introduced Su-7B series became the main Soviet fighter-bomber and...

. It enjoyed a long career in Soviet, later Russian, service and was widely exported to communist and Middle Eastern air forces, under names Su-20 and Su-22.

Development

Seeking to improve low-speed and take-off/landing performance of the Su-7B fighter-bomber, in 1963 the Sukhoi OKB with input from TsAGI

 created a variable-sweep wing technology demonstrator. The Su-7IG (internal designation S-22I, NATO designation Fitter-B), converted from a production Su-7BM, had fixed inner portions of the wing with movable outer segments which could be swept to 28°, 45°, or 62°. A fixed inner wing simplified construction, allowing the manufacturer to retain the Su-7 landing gear and avoiding the need for complex pivoting underwing hardpoints, and it minimized the shift in the center of pressure

 with change in wing sweep. The new wing also had extensive leading-edge slats and trailing-edge flaps. Su-7IG first flew on 2 August 1966 with V. S. Ilyushin at the controls, becoming the first Soviet variable geometry aircraft. Testing revealed that take-off and landing speeds had decreased by 50–60 km/h (27-32 kn, 31-37 mph) compared to the conventional Su-7.

The production aircraft was named Su-17 (NATO designation 'Fitter-C', factory designation S-32) and was unofficially dubbed Strizh (Стриж, martlet

) in service. Aside from the new wing, it differed from its predecessor Su-7 in having a new canopy and a dorsal fuselage spine for additional fuel and avionics. Su-17 first flew on 1 July 1969 with E. K. Kukushev at the controls.

A total of 2,867 Su-17 and its variants were built, of which 1,165 were exported to 15 nations.

 in 1970. The aircraft was used by both the Soviets and the government Afghanistan forces during the Soviet invasion of Afghanistan. High-altitude airfields and hot dusty climate created special operational challenges. In the summer, the take-off roll of the Su-17 increased 1.5-fold and landings frequently ended with burst tires and brake fires. Avionics failures were common due to heat and sand contamination.

However, the AL-21F engine proved tolerant of routine ingestion of sand and sand-contaminated fuel and by 1985 the combat readiness of the Su-17 fleet exceeded that of the Sukhoi Su-25

 and the helicopters. The first-series Su-17s were quickly replaced with more capable Su-17M3 and Su-17M4. Despite its durability and payload, the aircraft proved ill-adapted for combat in the mountainous terrain due to high attack speeds, low maneuverability, and the need to stay out of range of anti-aircraft artillery due to lack of significant armor protection, Although external armor was added around the engine, hydraulics, and fuel systems based on damage analysis, this was still insufficient compared to dedicated close air support Su-25s.

The S-52U two-seat combat-trainer, export version of the Su-17UM, with a completely re-designed nose housing the tandem cockpits for student and instructor.

Gun pods such as the GSh-23 based UPK-23 and SPPU-22 were utilized by the Su-17, Su-20, and Su-22. The SPPU-22 ground attack variant featured 30 degrees of traverse.

An experimental version of the Su-20 was built with fixed wings attached to an Su-17M fuselage, in an effort to increase Payload/range performance by eliminating the weight of the wing sweep system. Good results were obtained in flight tests in 1973 but further development was cancelled.

Tactical Reconnaissance versions of all variants could be made by fitting the KKR (Kombinirovanny Konteiner Razvedy – combined reconnaissance pod) on the centre-line pylon.
