The historic aircraft have a long-standing history of successful operations. So why were they decommissioned?
"The X-47B is a tailless, strike fighter-sized unmanned aircraft developed by Northrop Grumman as part of the U.S. Navy’s Unmanned Combat Air System Carrier Demonstration program. Under a contract awarded in 2007, the company designed, produced and is currently flight testing two X-47B aircraft. In 2013, these aircraft were used to demonstrate the first-ever carrier-based launches and recoveries by a relevant, low-observable, unmanned autonomous aircraft.
Perhaps more importantly, the aircraft proved that a semi-autonomous flying wing aircraft could successfully operate from an aircraft carrier and refuel from a tanker.In order to build and fly the X-47Bs, the U.S. Army had to implement some significant technological advancements. In the end, the first X-47B flew in 2011, and by 2015 its two active demonstrators had completed extensive flight and operational integration testing, making them ready for use on the battlefield. It was in August of 2014 that the U.S. Navy announced that it had integrated the X-47B into carrier operations.
Northrop Grumman further stated that “the X-47B UCAS is designed to help the Navy explore the future of unmanned carrier aviation. The successful flight test program is setting the stage for the development of a more permanent, carrier-based fleet of unmanned aircraft.”
