Mig-25 "FoxBat
Vs
The SR-71 "Blackbird"
Was the Mig-25 Foxbat and the upgrade Mig-31 Foxhound capable of intercepting an SR-71? This question comes up regularly at SR-71 symposiums and Blackbird speaker
events throughout the U.S. To put to rest this question is the purpose of this web page. During the cold War the Russians were highly concerned about the United State's XB-70 supersonic bomber project. In response, they built the Mig-25 which was designed to be a Mach 2.8 Interceptor for countering air targets in all weather conditions, by day and by night and in dense hostile electronic warfare environments. This was the USSR's answer to the design in the US of fast, high flying aircraft as the XB-70, North American F-108 and Lockheed SR-71. The MiG-25 lacked technological refinement, but its performance caused much concern in the west. It was designed to function both as a long- range interceptor and reconnaissance aircraft. The center fuselage is a big, welded steel fuel tank, so avionics, radar or cameras are in the nose. Speed is limited to Mach 2.83 mainly by controllability problems. The MiG-25 is a twin-finned high-wing monoplane with slightly swept wings and a variable angle tail plane. To improve the aircraft's longitudinal stability and to avert stall at steep angles and subsonic speed, there are two shallow upper surface fences on each wing. The high-wing monoplane configuration together with lateral air intakes both have the effect of reducing the loss of aerodynamic efficiency resulting from wing-fuselage interference. The aircraft is powered by two 11200kg Tumansky R-15D-300 single shaft turbojets, arranged in the tail section of the fuselage. The engines develop 11,200 kgf of thrust with fully selected afterburner. The engines provide a maximum speed of 3,000 km/hour at high altitude. The maximum speed at low altitude is 1,200 km/hour. The aircraft has a service ceiling of 22,500 meters. The range at altitudes between 9 and 11 km with speed of Mach 0.85 is 1,950 km. At higher altitudes between20 and 21 km and speed Mach 2.35, the range is 1,650 km. The maximum in-service g-load is 4.5g's.There are two-seat trainer versions of both the fighter and the reconnaissance version. Production of the fighter ended in 1983. The MiG-25 saw combat in several wars in the Middle East. Over 1200 have been built, of which about 75% were interceptors. The MiG-25 was produced by MAPO-MiG, the Moscow Aircraft Production Organisation MiG, which is based in Moscow and the Sokol Aircraft Manufacturing Plant Joint Stock Company at Nizhni Novgorod in Russia.
