View showing to advantage the Su-22's swing wing (30/63 degree sweep). In its time this high speed, medium range, low level ground attack/recce aircraft was the most potent of its kind in the Warsaw Pact. The M-4 was final export version and was manufactured from 1983 to 1990. In 1992, just before the split, Czechoslovakia had 49 Su-22M-4s and 8 Su-22UM-3Ks. Unfortunately 4009 was w/o nine months after this shot (18.3.93)
