Citat:The Su-17 entered service with the Soviet Air Force in 1970. The aircraft was used by both the Soviets and the Afghanistan government forces during the Soviet invasion of Afghanistan. High-altitude airfields and hot dusty climate created special operational challenges. In the summer, the takeoff 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 appearance of MANPADS such as the Soviet-made Strela 2 (smuggled from Egypt), and the American FIM-43 Redeye and later FIM-92 Stinger, presented a new threat and forced Su-17s to even higher operational altitudes. Revised tactics and retrofit of up to 12 flare dispensers which fired automatically during the attack run proved effective, and in 1985 only one Soviet Su-17 was lost to ground fire.

Citat:This Sukhoi Su-22M4 Fitter-K was in service of the East-German Air Force (Nationale Volksarmee/Luftstreitkräfte, NVA/LSK) as no. 706 and later in the German Navy as no. 25+31. The aircraft was part of the former 28th Naval Aviation Wing (Marinefliegergeschwader 28, MFG-28 ) at Laage AB. It is now preserved in the training shop at WTD61 Flight Test Center, Manching.
