The X-47B is a tailless, strike fighter-sized unmanned system currently under development by Northrop Grumman as part of the U.S. Navy’s Unmanned Combat Air System Demonstration (UCAS-D) program. Under a contract awarded in 2007, the company has designed, developed and is currently producing two X-47B aircraft. In the 2013 timeframe, these aircraft will be used to demonstrate the first carrier-based launches and recoveries by an autonomous, low-observable relevant unmanned aircraft. The UCAS-D program will also be used to mature relevant carrier landing and integration technologies, and to demonstrate autonomous aerial refueling by the X-47B aircraft.
