The service branch said Monday that the unprecedented MQ-25 program achievement was conducted on June 4 from MidAmerica Airport in Mascoutah, Illinois.
The receiver Navy F/A-18 Super Hornet approached the Boeing MQ-25 T1 Stingray drone and reportedly evaluated formation, wake survey, drogue tracking and "plugged" with the aircraft.
Fuel was then transferred from the test asset drone from its Navy-issued Aerial Refueling Store (ARS) to the fighter jet.
The maneuver required as little as 20 feet of separation between the drone and F/1-18 aircraft.
The Navy said the progress showed that MQ-25 could fulfill its tanker mission using the Navy-standard "probe-and-drogue" aerial refueling method.
Now, the Unmanned Aviation and Strike Weapons Program will continue testing the drone to include facets like flight envelope expansion, engine testing and deck handling demonstrations aboard an aircraft.
Test flight data is set to be analyzed to determine whether any adjustments are necessary.
According to Boeing, the "milestone" comes following 25 test flights of the MQ-25 T1, in addition to "extensive" simulations of aerial refueling.
The drone is set to be shipped to Norfolk, Virginia, for the deck handling trials on a Navy carrier later this year.
In the future, the Navy said the MG-25A Stingray will be the world's "first operational carrier-based unmanned aircraft [and] provide critical aerial refueling and intelligence, surveillance and reconnaissance (ISR) capabilities that greatly expand the global reach, operational flexibility and lethality of the carrier air wing and carrier strike group."
Boeing was awarded the contract to manufacture the aircraft in 2018, which the Navy says is critical to its Unmanned Campaign Framework.
"This is our mission, an unmanned aircraft that frees our strike fighters from the tanker role, and provides the Carrier Air Wing with greater range, flexibility and capability," Capt. Chad Reed, program manager for the Navy’s Unmanned Carrier Aviation program office, said in a statement. "Seeing the MQ-25 fulfilling its primary tasking today, fueling an F/A-18, is a significant and exciting moment for the Navy and shows concrete progress toward realizing MQ-25’s capabilities for the fleet."
"This history-making event is a credit to our joint Boeing and Navy team that is all-in on delivering MQ-25's critical aerial refueling capability to the fleet as soon as possible," Leanne Caret, president and CEO of Boeing Defense, Space & Security, said in a statement. "Their work is the driving force behind the safe and secure integration of unmanned systems in the immediate future of defense operations."
