Explanation

The Northrop Grumman X-47B is a demonstration unmanned combat air vehicle (UCAV) designed for aircraft carrier-based operations. The X-47B is a tailless jet-powered blended-wing-body aircraft capable of semi-autonomous operation and aerial refuelling. The X-47B first flew in 2011, and as of 2015, its two active demonstrators have undergone extensive flight and operational integration testing, having successfully performed a series of land- and carrier-based demonstrations. In 2014, the US Navy announced that it had integrated the X-47B into carrier operations alongside manned aircraft, and by 2015 the aircraft's primary test program was declared complete.
