With the success that was the Sukhoi Su-17 "Fitter" swing-wing product, it was only natural for Soviet authorities to allow its sale to global allies and this endeavor provided the basis for the Su-20 "Fitter-C" export mark - based largely on the Su-17M (S-32MK model). The Su-20 was delivered with a ranging radar system, improved navigation suite, and a modern attack system while being powered by an AL-21F-3 24,800 lb thrust engine. The aircraft also appeared in limited export quantity as a reconnaissance variant under the designation of "Su-20R" - these being based on the Su-17R reconnaissance model. The Su-17 was later developed into a much-improved export variant recognized as "Su-22".

Armament included 2 x 30mm Nudelman-Rikhter NR-30 series internal cannons for close-in work. The airframe also held some ten hardpoints for the carrying of various air-to-air and air-to-surface munitions. Its crew was one and the export model retained much of the form and function of the Soviet line. Operational use of the Su-20 fell to Egypt, Poland, and Syria where they served in the fighter-bomber and ground attack roles.©MilitaryFactory.com
