The MQ-25 Stingray, the refueling drone of the Navy, is its first fleet-based unmanned refueling aircraft, and it is going significantly ahead with the most considerable change in naval aviation for years. The U.S. aircraft carrier has been, most of the time, the heart of the United States’ power projection. Nevertheless, it has been vitally dependent on crewed aircraft for the most critical support operations, such as air refueling. Everything is different with the MQ-25. It is a totally different era when unmanned systems not only offer assistance but also change the carrier operations.
A Historic Aviation Milestone
The MQ-25 hit the headlines in June 2021, when a test aircraft from Boeing successfully transferred fuel during flight to a Navy F/A-18 Super Hornet. The test, conducted over Illinois, was not only a technological achievement—it was a milestone in the way unmanned systems complement crewed platforms. The Super Hornet flew only 20 feet from the unmanned MQ-25, holding station through both dry and wet contacts before taking on board fuel. This wasn’t proof of concept—it was proof of capability in realistic conditions.
More Than a Flying Tanker
Although the MQ-25’s stated purpose is to refuel carrier-based aircraft at range, its effect extends far beyond logistics. Rear Adm. John Meier, Commander of Naval Air Force Atlantic, has described the Stingray as a “revolutionary” move toward creating the Air Wing of the Future. By lifting the refueling load off F/A-18s—historically employed as ad hoc tankers—the Navy can now send more of those aircraft on strike and combat missions. The payoff? More firepower, longer reach, and greater efficiency without more pilots or platforms.
Proven on the Deck, Ready for the Fleet
Getting an unmanned aircraft onto the tightly choreographed deck of a carrier took careful testing. Initially, engineers tested the MQ-25 at Chambers Field in Norfolk by getting it to maneuver within lines painted on mock-ups of carrier decks using remote control. The simulations later led to live demonstrations on board the USS George H.W. Bush, confirming how the MQ-25 could be incorporated into routine deck operations.
A Strategic Building Block
The MQ-25 is not an independent test—it is the Navy’s first step toward creating a networked, hybrid force of manned and unmanned platforms. It is part of the larger movement toward manned-unmanned teaming (MUM-T), in which human pilots and autonomous vehicles work together as integrated teams.
Future success, according to defense analyst Heather Penney of the Mitchell Institute, will not only be based on constructing cutting-edge machines, but on systems where machine and human can understand each other’s strengths and weaknesses. That’s the kind of thinking found in initiatives such as the “Two View Autonomy Framework” that seeks to close the gap between operators and engineers as autonomy becomes more prevalent.
Moving Fast and Learning Faster
Since Boeing won the development contract in 2018, the MQ-25 program has been rapidly moving forward. Within a few years, it not only refueled an F/A-18 but also topped off an F-35C and an E-2D Advanced Hawkeye—showing its versatility throughout the fleet. The Navy has been pushing to get the MQ-25 into operational use as fast as possible, particularly as competitors are building systems intended to counter U.S. carrier superiority in high-threat operations.
A Glimpse Into What’s Next
The deployment of MQ-25s onto Ford- and Nimitz-class carriers will change the way the Navy projects airpower. With its capability to refuel strike aircraft away from the carrier, it enables the U.S. to reach farther without getting closer to enemy defenses. But equally significant, the Stingray opens the door to future unmanned systems—from surveillance drones to autonomous strike aircraft and loyal wingmen designs.
Each lesson gained from the MQ-25—technical, tactical, or procedural—is part of a greater push to transform naval aviation for the battles of the future. In a world defined by speed, precision, and stealth, unmanned vehicles like the MQ-25 won’t be bit players—they’ll be driving the mission.
