The engine for the MiG-15 trainers The RD-45 jet engine was the Soviet licence built version of the British Rolls-Royce RB-41 Nene turbine. It was installed in the early MiG-15 fighter planes. In Hungary it was used in the UTI trainers used by the Air Force. The People's Army introduced 49 two seater models of their first jet propelled plane, which served between 1951 and 1974.
