Joint Unmanned Combat Air Systems, or J-UCAS, was the name for the joint U.S. Navy and U.S. Air Force unmanned combat air vehicle procurement project. Originally two separate projects of the U.S. Air Force and Navy respectively: UCAV and UCAV-N; both programs merged in 2003.[1] The two vehicles involved in J-UCAS were the Boeing X-45 and Northrop Grumman X-47A Pegasus,[2] orginially part of UCAV and UCAV-N repectively.[1][3] J-UCAS was 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, Next-Generation Bomber, for the Air Force would launch. The program was revitalized into a Navy-only program named UCAS-D.[4][5]

The goal of the J-UCAS effort was to develop a "versatile combat network in which air and ground components are nodes that can be changed over time to support a wide range of potential missions."[2]
