A new US Navy carrier-based drone for refueling aircraft has begun flight testing with the first flight of a production-representative aircraft, the service announced, marking a key step toward bringing uncrewed systems into the refueling role.
The Navy says that the MQ-25A Stingray is the first operational carrier-based uncrewed aircraft system. Made by Boeing, the Stingray’s first test flight moves it closer to aircraft carrier operations and the refueling mission expected to extend the reach of crewed aircraft. The Stingray’s timeline to service has been repeatedly delayed.
The Navy and Boeing announced the first test flight on Monday. The April 25 test was not the first-ever flight of the MQ-25 concept, but it was the first test of a production-representative aircraft as the Navy starts up formal flight testing ahead of eventual service.
Over the weekend, the MQ-25A flew for approximately two hours at Boeing’s facility in Illinois and was controlled by Navy and Boeing air vehicle pilots via a ground control system. During the flight, the Stingray conducted several maneuvers and tests and demonstrated flight controls and navigation.
“Today’s successful flight builds on years of learning from our MQ-25A T1 prototype and represents a major maturation of the program,” Dan Gillian, vice president and general manager of Boeing Air Dominance, said, per a press release.
The sea service’s Stingray is a planned uncrewed replacement for the F/A-18E/F Super Hornet’s air-to-air refueling role within carrier air wings. The Navy has said the drone’s job will help extend the operational range of aircraft and free them up to focus on combat and surveillance roles.
The MQ-25 can carry up to 15,000 pounds of fuel and could help the Navy rethink the ranges of its aircraft carriers and fighters as China’s growing arsenal of anti-ship missiles threatens US naval forces.
“The MQ-25A is not just an aircraft,” Rear Adm. Tony Rossi, head of the program executive office for unmanned aviation and strike weapons, said, per the Navy’s press release.
He said that “it’s the first step in integrating unmanned aerial refueling onto the carrier deck, directly enabling our manned fighters to fly further and faster. This capability is vital to the future of naval aviation.”
The Navy began work on the MQ-25 in 2016, selected Boeing for production in 2018, and the Navy and Boeing flew a test asset for the first time the following year. The most recent flight test is the first for the MQ-25A, a production-design aircraft different from the earlier MQ-25 T1 test asset.
The MQ-25 T1 test drone previously showed off its refueling capabilities in 2021, flying in front of an F/A-18 and getting as close as 20 feet to the aircraft before extending the hose and drogue to plug into the fighter to transfer the fuel.
The service has navigated several delays and cost increases to the Stingray, which was originally supposed to be operational in 2024 but is now set to enter into service later this decade.
