Soviet Union — 7 museum-grade prints from this operator. The MiG-25 Foxbat shocked Western analysts when reconnaissance overflights demonstrated sustained Mach 2. 8+ performance at altitudes above 80,000 feet — capabilities that accelerated F-15 Eagle development and dominated Cold War aviation headlines through the 1970s. The MiG-17 Fresco bridged the Korean War jet era and the Vietnam air campaign — Soviet and Chinese pilots flew the type against F-86 Sabres over the Yalu while North Vietnamese Frescos later contested F-4 Phantom and F-105 Thunderchief strikes over Hanoi. The airframe's transonic handling and cannon armament made it a credible threat despite lacking radar-guided missiles; more than ten thousand Frescos and licensed variants rolled off production lines in the USSR, China, Poland, and Czechoslovakia. The MiG-19 Farmer entered Soviet service in 1955 as the first USSR fighter cleared for sustained supersonic flight in level cruise — a milestone that followed the MiG-17's transonic success and preceded the MiG-21's delta-wing revolution. Licensed J-6 production in China made the Farmer one of the most widely exported Soviet jet designs of the 1960s, equipping Pakistan, Egypt, and North Vietnam alongside Warsaw Pact allies.
