General Information
The Northrop Grumman X-47B is an unmanned combat aerial vehicle (UCAV) designed as a technology demonstrator for aircraft carrier-based operations. Developed by Northrop Grumman for the U.S. Navy, the X-47B is a tailless, strike fighter-sized aircraft capable of semi-autonomous operation and aerial refueling. It was part of the Unmanned Combat Air System Demonstration (UCAS-D) program to prove the feasibility of operating unmanned aircraft from carriers. While the X-47B itself is not intended for operational deployment, it successfully demonstrated autonomous carrier launches and recoveries, as well as aerial refueling, paving the way for future unmanned carrier aviation.
