Designed to meet the North American B-70 "Valkyrie" jet-powered bomber, the MiG-25 Foxbat was a successful Soviet-era aircraft. The MiG-25 did well to counter the Lockheed SR-71 spy plane as well as force the production of the McDonnell Douglas F-15 Eagle. Some 1,190 MiG-25s of all types were eventually produced covering interception, reconnaissance, ELINT, training and bombing duties.
