The Northrop Grumman X-47B Unmanned Combat Air System Demonstrator (UCAS-D) carried out its first arrester landing on an aircraft carrier on July 10. The aircraft- known as 'Salty Dog 502' - landed on the deck of the USS George H W Bush (CVN 77) under way in the Atlantic Ocean off the coast of Virginia, having flown from NAS Patuxent River, Maryland. In doing so it became the first tailless unmanned air system ever to perform an arrested landing on a US Navy carrier deck.
