X-47B First Autonomous Air Refueling 22 Apr 2015

The first autonomous aerial refueling (AAR) of an unmanned aircraft was made by the X-47B on 22 April 2015, 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. 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. Want more X-47B videos?
