April 3 (UPI) -- NASA has chosen Lockheed Martin Aeronautics Company to design, build and test a quieter supersonic aircraft. The Low-Boom Flight Demonstration contract is valued at $247.5 million.
As contract winner, Lockheed Martin is tasked with building the Low-Boom Flight Demonstration X-plane, an experimental airplane that will reach supersonic speeds but not trigger a supersonic boom. Instead, the quieter supersonic jet will produce a "thump." The name for LBFD technology is Quiet Supersonic Technology, or QueSST.
