Northrop Grumman just posted this two minute video review of recent flight test activities for US Navy’s X-47B Unmanned Combat Air System demonstration aircraft at Edwards AFB, California. The two aircraft will be moved from Edwards to the US Navy’s test centre at NAS Patuxent River, Maryland. The first aircraft will be tested to 115% of required performance; the second will be tested to 135%, but envelope expansion is not a priority for either aircraft.
