The J58 engine was developed in the late 1950s by Pratt & Whitney Aircraft Division of United Aircraft Corp. to meet a U.S. Navy requirement. It was designed to operate at speeds of Mach 3+ and at altitudes of more than 80,000 feet. The J58 was the first engine designed to operate for extended periods using its afterburner, and it was the first engine to be flight-qualified at Mach 3 for the U.S. Air Force.
Two J58s powered the highly-sophisticated Lockheed SR-71 high-altitude strategic reconnaissance aircraft as well as its forerunners, the Lockheed A-12 and YF-12A prototype interceptor. In July 1976, J58 engines powered an SR-71 to a world altitude record of 85,069 feet and another SR-71 to a world speed record of 2,193 mph.

Day 5, Friday, the final display day of RIAT 2015. Love seeing the Osprey, it defies the laws of physics. On the ground it's crew were friendly too. My laptop now looks scarier for a couple of Osprey stickers.
