The Polish Air Force still has many Su-22 Fitters in service, but the Sukhoi-version in the photo is long gone. The Su-20 Fitter-C was the export version of the Su-17M.
I took the photo during the airshow at Poznan-Lawica in August 1991. The first and last time I saw this type of Fitter. 6264 is preserved in the town of Wejherowo.
