The Northrop Grumman X-47B is an American demonstration Unmanned Combat Aerial Vehicle (UCAV) which first flew in 2011. The X-47 project began as part of DARPA's J-UCAS program, and is now part of the United States Navy's UCAS-D (Unmanned Combat Air System Demonstration) program, which aims to create a carrier-based unmanned aircraft. Unlike the similar Boeing X-45, the development of the original X-47A Pegasus was company-funded. The X-47A's follow-on naval version is designated X-47B.
