Sukhoi Su-20 aircraft
A variable-sweep fighter-bomber with a service history at Powidz.
Idioma del contenido
The museum’s Su-20 served at Powidz with the 7th Bomber-Reconnaissance Regiment. It arrived there in 1976 and accumulated more than 1,500 flying hours over sixteen years. Today, the preserved airframe is displayed without an engine. Moving it to the museum was a substantial transport operation: it travelled in six sections on three military transport platforms.
Reassembly was carried out with help from the 21st Tactical Air Base and the 33rd Transport Air Base. The exhibit’s size, and the need to divide it into sections, show how much preparation is involved in moving an aircraft into a museum collection.
Developed in 1972, the Su-20 was an export version of the Soviet Su-17M. Its most distinctive feature is its variable-sweep wings. Changing their angle helped adapt the aircraft to different flight conditions. One aim in the development of this aircraft family was to improve take-off and landing compared with the earlier Su-7. The Su-20 performed fighter-bomber duties; it was neither a passenger nor a transport aircraft.
The aircraft has been cleaned and repainted silver, replacing its former camouflage. Its equipped cockpit remains closed to visitors. Any future access depends on further work; the museum has not confirmed an opening date.

This Su-20 flew with a military unit at Powidz. It arrived there in 1976. Over sixteen years, it spent more than 1,500 hours in the air. The aircraft on display no longer has its engine.
Moving such a large object meant separating it into six sections. They occupied three military transport platforms. Specialists from two air bases helped put the aircraft back together. Before becoming an exhibit, it had to make a journey by land.
The Su-20 has variable-sweep wings. This means that sections of its wings can change angle, helping the aircraft adapt to different flight conditions. Improving take-off and landing was one reason for developing this design. The Su-20 was a military fighter-bomber, and its design was derived from the Su-17M.
The aircraft has been cleaned and repainted silver, replacing its former camouflage. Its equipped cockpit remains closed to visitors. Any future access depends on further work; the museum has not confirmed an opening date.
