The Lockheed Martin Skunk Works revealed a hypersonic aircraft design that can take off and land conventionally using turbine-based combined-cycle engine technology. The company said it has been working with rocket propulsion specialists Aerojet for several years on the project, using company funds. Although the design could lead to a Mach 6 unmanned strike aircraft, Lockheed Martin has dubbed it the SR-72, after the company’s SR-71 Blackbird manned strategic reconnaissance aircraft that reached Mach 3 but was retired in 1997.

Boeing reported the first flight of the X-48C blended wing body (BWB) research aircraft at Edwards AFB on August 7. The unmanned 8.5-percent scale model reached 5,500 feet during a nine-minute flight. A week later, however, the company’s third X-51 Waverider hypersonic testbed flight ended in failure when its scramjet failed to ignite.

A second test flight of the X-51A WaveRider has not gone according to plan. Successfully dropped from the left wing of a B-52H Stratofortress, and then accelerated to over Mach 5 by a solid rocket booster, the unmanned, scramjet-powered, hypersonic vehicle crashed in the Pacific Ocean off Point Mugu NAS, Calif. on June 13

The Boeing X-51A WaveRider hypersonic vehicle, powered by a Pratt & Whitney Rocketdyne scramjet engine, achieved aviation history this week by making the longest ever combustion ramjet-powered supersonic flight. During its first jaunt, the craft reached 70,000 feet and an approximate speed of Mach 5 on a 200-second flight over the Pacific Ocean on May 26 at 10 a.m. before it was purposely crashed into the water.
