Between 1961 and 1965, the Hungarian Air Defense Force purchased MiG-21F-13 Fishbed-C and MiG-21PF Fishbed-D interceptor aircraft. The old MiG-15bis Fagot-B aircraft were released. Part of them became training aircraft, while the other part became reconnaissance aircraft.
A new reconnaissance squadron was formed with MiG-15bis at Kecskemét and at Taszár Airport in 1966. At the same time, IL-28 Beagle reconnaissance and target-towing aircraft were withdrawn.
At Szolnok airport, the pilot school received 18 new L-29 Delfin trainer aircraft from 1964 to 1965. The second squadron of the school used MiG-15bis Fagot-B for advanced training.
