Joint Unmanned Combat Air Systems
From Wikipedia, the free encyclopedia
Joint Unmanned Combat Air Systems, or J-UCAS, was the name for the joint U.S. Navy/U.S. Air Force unmanned combat air vehicle procurement project. The two vehicles involved in the project were the Boeing X-45 and Northrop Grumman X-47. J-UCAS is being managed by the Defense Advanced Research Projects Agency. In the 2006 Quadrennial Defense Review it was stated that the J-UCAS program would be terminated and instead a new long-range strategic bomber program has been launched [1].
