The Sukhoi Su-17 (NATO reporting name: Fitter) is a Soviet attack aircraft developed from the Sukhoi Su-7 fighter-bomber. It enjoyed a long career in Soviet, later Russian, service and was widely exported to communist and Middle Eastern air forces as the Su-20 and Su-22.

Since the 1970's, the swing-wing Soviet fighter-bomber has been in service in the Warsaw Pact and third World countries.
