Pratt & WhitneyRocketdyne built the SJY61 scramjet engine at the heart of the X-51A cruiser. The Air Force beganWednesday's test at 1 p.m. EDT (1700 GMT), when the B-52Stratofortress hauling the X ...

The Air Force described the X-51 is an unmanned scramjet demonstration aircraft for hypersonic (Mach 6, or approximately. 4,000 mph at altitude) flight testing.

NASA’s X-43A was a small, unmanned experimental aircraft that, in 2004, shattered world records by flying at nearly Mach 10 (almost 7,000 mph), becoming the fastest air-breathing vehicle in history.
