The first generation jets The MiG-15bis is a first generation Soviet jet-propelled fighter plane. It was first used in combat in the Korean War. The Hungarian People's Army introduced 104 of them, which served between 1962 and 1975. NATO reporting name: Fagot-B. It was manufactured in huge numbers The prototype developed in the Mikoyan-Gurjevich design bureau was first flown on 30 December 1947. It was initially propelled by a Soviet copy of the Rolls-Royce RD-45 "Nene" gas turbine, but the bis models were equipped with Klimov VK-1 engines. Over 12,000 models of the MiG-15 were made in the Soviet Union. They were also licence built in Czechoslovakia, Poland, and China. The number of these variations manufactured exceeds 18,000. In Hungary The jet age of the Hungarian army began in 1951 when the first MiG-15s arrived: 10 single-seat fighter planes and 4 UTI MiG-15 twin-seated trainers. The first solo Hungarian flight was made on August 24, 1951 by Lieutenant Colonel István Mezőfi. The MiG-15s were first displayed to the public on April 4, 1952: a twenty plane strong formation flew over Heroes Square. The first ejector seats are linked to this model too. The first successful emergency exit was performed by Lieutenant István Ferencz on July 17, 1952. Retirement from the army From the beginning of the 1960s, the emergence of more modern, newer planes precipitated the slow retirement of the MiG-15 from military service. In 1966, 30 planes were withdrawn from service in a single year. At the beginning of the 1970s the remaining models received a camouflage paintjob – their underside was painted blue – and they were used as reconnaissance planes. The last MiG-15 was retired on August 31, 1975. The plane on display was made in the Soviet Union in 1951; serial number: 31530912.
