US Navy X-47B first to complete autonomous aerial refueling
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.
