Patuxent River, MD — Testing of the X-47B Unmanned Aerial System is continuing at Patuxent River Naval Air Station (NAS).

The Navy awarded a $64 million contract modification to Northrop Grumman in June 2014 to continue X-47B CVN and AAR research, development, test and evaluation efforts at NAS Patuxent River.

According to program officials, โ€œIf resources allow, the Navy may demonstrate autonomous engagement flight testing in fiscal year 2015.โ€

NAVAIR and Northrop Grumman conducted AAR testing with a surrogate aircraft in January 2012 to test the X-47B software that allows the test plane to mimic the interaction between the tanker and the aircraft receiving the fuel, but stops short of a mid-air refueling.

โ€œThe X-47B will use a hybrid GPS/vision-based relative navigation system in conjunction with its autonomous flight control system to establish and maintain a precise distance between tanker and the receiver aircraft,โ€ according to a statement from Northrop Grumman

Presently, one of the two Pax River X-47Bs is being configured for the aerial refueling capability.
