The Sukhoi Su-17 (NATO reporting name: Fitter) is a Soviet variable-sweep wing fighter-bomber developed from the Sukhoi Su-7. It enjoyed a long career in Soviet, later Russian, service and was widely exported to Eastern Bloc, Arab air forces, Angola and Peru as the Su-20 and Su-22. It is the first variable-sweep wing of Russian/Soviet origin. The Su-17M4/Su-22M4 (Fitter-K) was the final production version with considerably upgraded avionics, including RSDN navigation (similar to LORAN), beacon navigation, inertial navigation, a more powerful (Klyon) "Kлён-54" laser rangefinder, radio compass, and SPO-15LE ("Sirena") radar-warning system. Additional fuselage inlets (including ram-air inlet at the base of the fin) to improve engine cooling airflow, fixed air intake shock cone. Many aircraft were equipped for the use of TV-guided missiles and BA-58 Vjuga pod for anti-radiation missiles. AL-21F-3 engine. Export version was designated Su-22M4 (factory S-54K). First flight: 19 June 1980 with Yu. A. Yegorov at the controls. Su-17M4 was manufactured 1981–1988, Su-22M4 was manufactured 1983–1990. The Sukhoi Su-22M4 on exhibit at the Technik Museum Speyer was originally from the East German Air Force, which had acquired altogether 48 models of this type between 1984 and 1987. With the take-over of the East German army by the Federal Armed Forces after the reunion of Eastern and Western Germany in 1989, these jets were taken out of service in 1993.
The Technik Museum Speyer (Speyer Museum of Technology) is a technology museum in Speyer (south-west of Heidelberg), Germany. The collection includes: aircraft, classic vintage cars, racing- and classic motorcycles, historic fire engines, ships, massive steam locomotives, mechanical instruments, rarities and fashions. A special part of the collection is the Russian Space Shuttle Buran. The collection is displayed both indoors and outdoors, and finally there is an IMAX theater. The museum was established in 1991. It is closely associated with the Technik Museum Sinsheim (Sinsheim Museum of Technology). The latter suffered from a lack of space and a second location was opened in Speyer.
