The first generation Soviet fighter The MiG-17PF is a jet-propelled Soviet fighter plane. More than 10,000 of its various models were made. The Hungarian People's Army introduced 12 of them, which served between 1955 and 1974. NATO reporting name: Fresco. The MiG-15 was developed further The prototype was developed in the Mikoyan-Gurevich design bureau and first flew in 1950. The plane was developed by improving on the MiG-15; their structure is mostly the same. The most significant innovation were the new double swept wings. Furthermore, the upper part of the wings received 3 guiding plates each, while the MiG-15 had only 2. A ventral fin was placed at the rear of the body below the engine. Initially, the MiG-17 used the Klimov VK-1 gas turbine jet engines that were also used on the MiG-15, but a few later models like the PF were equipped with the VK-1 afterburner version, the VK-1F. The model was introduced into the Soviet army in 1952 where it was manufactured until 1958. It was later also produced in Poland and China. The model was used by all member states of the Warsaw Pact as well as numerous African and Asian countries. It was used for the longest time by Albania. In the Vietnam War The MiG-17 was first used in combat during the Vietnam War. Although it was slower than the more modern MiG-21, North Vietnamese pilots liked it for its good maneuverability. The MiG-17 succeeded in shooting down many more modern fighter planes. The plane was also used in the Arab-Israeli war. Training had to be done without an instructor Hungary introduced the F and PF versions. The F used a gas turbine with an afterburner and the PF was the same but equipped with an on-board radar. Theoretical retraining for the MiG-17PF began on 15 February 1955. The first six planes arrived by train to Kecskemét on April 23, 1955. By this time the pilots were completing theoretical training in the Soviet Union. Since there was no two-seated version of this model, the plane had to be flown alone after theoretical training. The Hungarian People's Army used 20 F version planes without losses. One out of 12 PF planes one was destroyed causing one casualty. The PF on display was made in the Soviet Union in 1955; serial number: 0405.
