The end of the Second World War saw the victorious Allied nations desperately attempting to secure details of German jet technology and high speed research data, information which could be applied to their own jet projects. Using this information and engine technology obtained from Britain, the Soviet Union introduced the diminutive Mikoyan-Gurevich MiG-15 in 1949 one of the most capable of the early jet fighters and even as this aircraft was proving effective during the Korean War, the Soviets were already working on its successor. The larger and faster Mig-17 Fresco may have given the appearance of being nothing more than a larger incarnation of its predecessor, however, this was in fact a completely redesigned aircraft, incorporating many improvements over the MiG-15 and a significant upgrade in Soviet jet capability.
The MiG-17 was designed to perform the role of bomber killer and was never intended as a dogfighter, however its exceptional agility would allow this aircraft to score combat victories over much heavier and more modern American designs. Dismissing the aircraft as nothing more than an upgraded MiG-15, the Vietnam War proved to be something of a sobering experience for the US Air Force, as some of their most modern aircraft would fall victim to the guns of the MiG-17, even though this had itself been superseded by more modern designs. Lighter and much more manoeuvrable than the US aircraft, the subsonic MiG-17 would claim victories over such aircraft as the F-105 Thunderchief and McDonnell Douglas Phantom, which would result in the US developing new agile air superiority fighters, in the years immediately following the end of the conflict.
