The Boeing Phantom Ray is an American demonstration stealth unmanned combat air vehicle (UCAV) being developed by Boeing using company funds. The autonomous Phantom Ray is a flying wing around the size of a conventional fighter jet, and first flew in April 2011. It will conduct a program of test flights involving surveillance, ground attack and autonomous aerial refueling missions.[2][3]

Design and development

The Phantom Ray project, called "Project Reblue" internally at Boeing, was first conceived in mid-2007, and started in earnest in June 2008. The project was secret within the company, except for a small number of executives and engineers, until May 2009.[4]

Developed by the Boeing Phantom Works, the Phantom Ray is based on the X-45C prototype aircraft,[5] which Boeing originally developed for the Defense Advanced Research Projects Agency (DARPA), the U.S. Air Force, and the U.S. Navy Joint-Unmanned Combat Air System (J-UCAS) program in 2002. The Phantom Ray was not aimed at any particular military program or competition,[6] although Boeing may use the design as an entry for the Navy's Unmanned Carrier-Launched Surveillance and Strike (UCLASS) program.[7]

The Phantom Ray was unveiled on May 10, 2010, in St. Louis, Missouri.[3][8] In late November 2010, low-speed taxi tests were carried out in St. Louis.[9][10] The demonstrator aircraft is to perform ten test flights over six months, supporting missions such as intelligence, surveillance and reconnaissance; suppression of enemy air defenses; electronic attack; hunter/killer; and autonomous aerial refueling.[2] Boeing anticipates that the Phantom Ray will be the first of a series of new prototype aircraft.[3]

The Phantom Ray was scheduled to make its maiden flight in December 2010 from NASA's Dryden Flight Research Center,[3][9] but this was later rescheduled, and the aircraft first flew on April 27, 2011, from Edwards AFB,[11][12][13] having been carried there by the Boeing 747 Shuttle Carrier Aircraft.[11][13][14]
