A new hypersonic spy plane, capable of flying up to six times faster than the speed of sound, is being developed by aerospace giant Lockheed Martin Corp., according to company officials.
The new aircraft, known as the SR-72, is the unmanned successor to Lockheed’sSR-71 Blackbird, a twin-engine, two-seater, supersonic aircraft that was developed in the 1960s. The company’s new spy plane will be able to fly twice as fast as the Blackbird and three times faster than current fighter jets, accelerating to Mach 6, which is six times thespeed of sound, or more than 3,500 mph (5,600 km/h).
