X-47B First to Complete Autonomous Aerial Refueling
The X-47B successfully conducted the first ever Autonomous Aerial Refueling (AAR) of an unmanned aircraft April 22, completing the final test objective under the Navy's Unmanned Combat Air System demonstration program.
While flying off the coast of Maryland and Virginia, the X-47B connected to an Omega K-707 tanker aircraft and received over 4,000 pounds of fuel using the Navy's probe-and-drogue method.
"What we accomplished today demonstrates a significant, groundbreaking step forward for the Navy," said Capt. Beau Duarte, the Navy's Unmanned Carrier Aviation program manager. "The ability to autonomously transfer and receive fuel in flight will increase the range and flexibility of future unmanned aircraft platforms, ultimately extending carrier power projection."
During the test, the X-47B exchanged refueling messages with a government-designed Refueling Interface System (RIS) aboard the tanker. The aircraft autonomously maneuvered its fixed refueling probe into the tanker's drogue, also known as the basket, the same way a Navy pilot would refuel a manned aircraft.
