Mikoyan-Gurevich MiG-25 The MiG-25's capabilities were not discovered until 1976 when Viktor Belenko, a Soviet MiG-25 pilot, defected to Japan. Subsequent analysis revealed a simple-yet-functional design with vacuum-tube electronics, two massive turbojet engines, and sparing use of advanced materials such as titanium. A capable interceptor, the MiG-25 was widely exported by the Soviet Union. The first MiG-25s entered service with the Iraqi Air Force in 1980 during the Iran-Iraq War. #avgeek #Mig
