Boeing Phantom Ray

The Boeing Phantom Ray is an American demonstration stealth unmanned combat air vehicle developed by Boeing Phantom Works. It is an autonomous flying wing about the size of a conventional fighter jet, based on the X-45C prototype that Boeing originally developed for the DARPA, Air Force and Navy Joint Unmanned Combat Air Systems program. The project, internally called Project Reblue, was conceived in mid-2007, officially began in June 2008 and stayed secret within Boeing until May 2009. The aircraft was unveiled on 10 May 2010, began low-speed taxi tests in November 2010 and first flew in April 2011. It was not aimed at any particular military program, though Boeing considered the design for the Navy UCLASS program, and the developers said it can carry 4,500 pounds of payload.
