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.
The Northrop Grumman X-47B is a unmanned combat air vehicle (UCAV) designed for carrier-based operations. Developed by Northrop Grumman, the X-47 project began as part of DARPA's J-UCAS program, and is now part of the United States Navy's Unmanned Combat Air System Demonstration (UCAS-D) program. The X-47B is a tailless jet-powered flying wing capable of semi-autonomous operation and aerial refueling.
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 probe-and-drogue method.
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.
Over the last few years, the Navy accomplished several significant firsts with the X-47B that showcased the Navy's commitment to unmanned carrier aviation. With the completion of this program, the service continues to develop its future unmanned carrier-based platform, known as UCLASS.
