X-47B Demonstrates Autonomous Aerial Refuelling

X-47B RefuelA new milestone in the history of unmanned aircraft was made last week, as ‘Salty Dog 502′ the first drone designed to operate from US Navy carriers linked to a drogue of an Omega tanker off the coast of Maryland.

The autonomous aerial refuelling (AAR) tests performed by the Unmanned Carrier Air Vehicle demonstrator (UCAS-D) this month represent the finale of this ambitious program, Naval Air Systems Command said this week. Following these tests the two X-47B unmanned aerial vehicles built by Northrop Grumman will be sent to museums or rest at the boneyard at Davis Monthan Air Force Base, Ariz., as the Navy’s UAS section, PMA-268 is focused on the next generation program – the Unmanned Carrier Launched Surveillance and Strike (UCLASS). The contract funding these refueling tests will end in June 2015.

Despite call in Congress to extend testing on the Northrop platforms, the Navy said the two programs are different and the costs involved in converting the UCAS-D to meet UCLASS requirements would be prohibitive, within the current program budget.

Under the UCAS-D testing program the two jet-powered drones, named Salty Dog 501 and Salty 502 performed catapult launch and arrested recovery abroad the aircraft carrier George H.W. Bush (CVN-77) in 2013, and extended the mission to conduct autonomous aerial refueling tests in 2015.

NAVAIR said the scope of the planned testing included the catapult launch and arrested recovery aboard a Navy aircraft carrier — both which occurred on the USS George H.W. Bush (CVN-77) in 2013 — as well as an autonomous aerial refuelling test.
