Raytheon's re-engineered Patriot radar prototype uses two key technologies - active electronically scanned array, which changes the way the radar searches the sky; and gallium nitride circuitry, which uses energy efficiently to amplify the radar's high-power radio frequencies (PRNewsFoto/Raytheon Company)

X43a2_nasa_scramjet

X43A Scramjet (supersonic combusting ramjet) Top Speed: 7,500 MPH A variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow. As in ramjets, a scramjet relies on high vehicle speed to forcefully compress the incoming air before combustion (hence ramjet), but a ramjet decelerates the air to subsonic velocities before combustion, while airflow in a scramjet is supersonic throughout the entire engine. This allows the scramjet to operate efficiently at extremely high speeds.

X-2 2

Bell X-2 Starbuster Top Speed: 2,094 MPH An X-plane research aircraft built to investigate flight characteristics in the Mach 2–3 range. The X-2 was a rocket-powered, swept-wing research aircraft developed jointly in 1945 by Bell Aircraft Corporation, the U.S. Air Force and the National Advisory Committee for Aeronautics (NACA) to explore aerodynamic problems of supersonic flight and to expand the speed and altitude regimes obtained with the earlier X-1 series of research aircraft.
