Russian MiG-25R upgrade/ SLEP

Period for MiG-25 Airplane Service Increased to More than 35 Years

((Airplanes in storage will be returned to service, in addition to upgrades. Discussion actually centers around MiG-25R. 200 – 220 of the reconnaissance variants were built in different versions by the time production ended in 1982. There are two regiments in the Russian air force, and 143 MiG-25R are in service abroad. Not further translated.))
