On November 20, 1965 an A-12 Blackbird exceeded Mach 3.2 and a sustained altitude of 90,000 feet. A stripped down, highly modified Soviet Mig-25 did break some of the Blackbirds records, however the SR-71 regained those records in July, 1976
West Coast to East Coast of USA (National Record-Speed Over a Recognized Course): Coast to Coast Distance: 2,404.05 statute miles...Time: 1 hr 07 min 53.69 secs...Average Speed: 2,124.51 mph
Los Angeles To Washington D.C. (World Record): Distance: 2,299.67 statute miles...Time: 1 hr 04 min 19.89 secs...Average Speed: 2,144.83 mph
St Louis To Cincinnati (World Record): Distance: 311.44 statute miles...Time: 8 mins 31.97 secs...Average Speed: 2,189.94 mph
Kansas City To Washington D.C. (World Record): Distance: 942.08 statute miles...Time: 25 mins 58.53 secs...Average Speed: 2176.08 mph
Mig Pilots were forbidden to exceed Mach 2.5. There was a total of three engine instruments and the airspeed indicator was redlined at 2.8 Mach.
Above Mach 2.8 the engines would overheat and burn up. The Americans had clocked a Mig-25 over Israel at Mach 3.2 in 1973. Upon landing in Egypt, the engines were totally destroyed. We did not understand that the engine destruction was inevitable.
The combat radius is 186 miles.
Without using afterburner; staying at optimum altitude and not maneuvering, the Mig can fly in a straight line for 744 miles.
The plane was so heavy, at 64,200 pounds, that Soviet designers had to eliminate a pilot ejection system.
1. A Mig-25 or Mig-31 has never fired a missile at an SR-71.
2. SR-71 Pilots state that the Mig-25/31 never posed a serious threat to their aircraft.
3. The Mig-25 can only sustain Mach 2.8 for a short duration due to engine overheat.
4. The Mig-25 can only sustain an altitude of 78,740 feet for two minutes maximum.
5. In 1973, Kelly Johnson, designer of the SR-71 Blackbird, stated that the Mig-25 Foxbat has the inherent capability to outperform the SR only in maneuverability. However, he stated, it would be the missile and not the aircraft that would require the maneuverability to intercept a Blackbird.
6. The SR-71 routinely cruised at Mach 3.2 in continuous afterburner at 80-85,000 feet. The speed and altitude of an SR-71 coupled with superior Defensive electronics has prevented any intended intercept of the Blackbird either by land based missiles or airborne Interceptor threats.
7. Almost all SR-71 Blackbird Reconnaissance Aircraft are now in Museums throughout the United States, having flown for 32 years with the distinction of being the "The highest flying and fastest air breathing aircraft in the world".
