In 1976 an Air Force SR-71 Blackbird spy jet set the world aviation speed record of 2,193 mph. More than 40 years later, the record still stands.Was the A-12 faster than the SR-71?
The numbers show that the A-12 was a little faster and could climb a little higher than the SR-71. It was, after all, a significantly lighter aircraft. Of course, the A-12 couldn't carry as much fuel, and its sensor payload was less, but an A-12 was spared the need for a 2-man crew.What is the top speed of the SR 71 Blackbird?
The top speed of the SR-71 blackbird is Mach 3+, or roughly 2200 miles per hour. A straight course speed record was set in July 1976 of 2193.167 mph.How much thrust does a SR-71 have?
The SR-71 Blackbird is powered by two Pratt & Whitney J-58 turbo-ramjets, each developing 32,500 pounds of thrust with afterburning. The critical problems concerning supersonic flight with air breathing engines are concentrated in the air inlet area.
