The SR-71 Blackbird cruising speed was Mach 3.2 or roughly 2,450 mph. On the 27th and 28th of July, 1976, and SR-71A set speed and altitude records (Altitude in Horizontal Flight: 85,068.997 ft. and Speed Over a Straight Course: 2,193.167 mph). Some estimates claim the SR-71 can fly well over Mach 3.3 and can reach altitudes in excess of 100,000 feet. But these numbers we know for a fact. What’s the fastest plane in the world? Now you know.
Too Fast To Be Caught
Well over a hundred missiles were shot at the SR-71, but the Blackbird was just too fast and its jamming technology was too sophisticated for one to ever catch up. The plane’s unique inlet/engine/afterburner design is only inlet/engine/afterburner combination in the world that used less fuel as the aircraft gained speed at supersonic levels. The turbojet engine functioned more like a turbo ram engine over 2,000 mph because it bypassed a lot of the air around the engine back into the afterburner. Which is critical. At 2,100mph roughly 80% of the thrust was from the “Ram Thrust”.
Legendary Last Flight
On it’s last flight ever, the SR-71 Blackbird set a speed record. The aircraft flew from Los Angeles to Washington, D.C. in 1 hour, 4 minutes, and 20 seconds. It averaged 2,124 miles per hour on this flight. Once it landed in D.C. it went straight into the Smithsonian. The SR-71 served as an unparalleled force multiplier with its advanced sensors and mission critical reconnaissance. Even with its short operational life span the SR-71 set the stage for the development of supersonic and hypersonic technology.
