What is the Boeing MQ-25 Stingray and what is it used for?

Ian Stephens
In short

Understand the Boeing MQ-25 Stingray’s carrier tanker role, probe-and-drogue refuelling, flight tests and why it is not a fighter jet.

The Boeing MQ-25 Stingray is a jet-powered, uncrewed aircraft developed for the US Navy as a carrier-based aerial-refuelling tanker. It is designed to launch from a carrier, transfer fuel to naval aircraft through a probe-and-drogue system, and return for an arrested landing—not to operate as a fighter jet.

For our Aviation & Real-World Flying readers, the key distinction is its role: this is an organic carrier tanker, not a small reconnaissance drone or a Boeing fighter. Boeing is the prime contractor, while the US Navy is the customer and intended operator.

What kind of aircraft is the Boeing MQ-25 Stingray?

The MQ-25A is a single-engine, carrier-capable uncrewed aircraft with folding wings, catapult-compatible landing gear and an arresting hook. It has no cockpit or pilot on board; human operators supervise the mission through control stations and communications links.

Under the US military designation system, M denotes a multi-mission aircraft and Q denotes an uncrewed aircraft. MQ-25A is the formal designation, while Stingray is the name. The aircraft itself is one part of a wider system that also includes mission-control equipment, datalinks, carrier infrastructure and support personnel.

What is the MQ-25 used for?

The MQ-25’s primary use is transferring fuel to other carrier-air-wing aircraft while they are airborne. Intended receivers include the F/A-18E/F Super Hornet, EA-18G Growler and F-35C Lightning II; Boeing’s T1 demonstrator has also refuelled an E-2D Advanced Hawkeye.

  • Extend combat radius: fighters can fly farther from the carrier while retaining the fuel required for combat and recovery.
  • Increase endurance: aircraft can remain on patrol, escort or surveillance tasks for longer.
  • Release fighters from tanker duty: fewer Super Hornets need to carry the buddy-refuelling store.
  • Reduce crew exposure: no aircrew member has to be aboard the tanker aircraft.
  • Support carrier integration: the programme introduces an operational uncrewed aircraft system into the carrier air wing.

The programme has also included an intelligence, surveillance and reconnaissance contribution, but that is secondary to refuelling. Our overview of the different aircraft and support roles found in a carrier air wing provides useful context.

Why does the US Navy need an uncrewed tanker?

The Navy needs an organic tanker because land-based refuelling aircraft cannot always follow a carrier into a distant operating area. A tanker launched from the same ship can move with the air wing and support missions without depending on a nearby runway.

Carrier air wings have used F/A-18E/F Super Hornets equipped for buddy tanking. That method works, but each tanker sortie occupies a combat aircraft and pilot while consuming fighter fatigue life, maintenance hours and fuel. The MQ-25 is intended to move much of that routine workload onto a purpose-built support aircraft.

It does not replace a large land-based tanker on a one-for-one basis. Aircraft such as the KC-135 carry far more fuel, but cannot launch from an aircraft carrier. Our explanation of how the KC-135’s boom-refuelling method works shows the practical difference.

How does the Stingray jet refuel another aircraft?

The Stingray transfers fuel through a flexible hose and basket-shaped drogue deployed from an underwing aerial-refuelling store. The receiving aircraft must have a compatible probe; the Navy’s F-35C does, whereas the land-based F-35A uses a boom receptacle instead.

  1. Mission assignment: operators provide the route, tanker orbit, timing and fuel plan.
  2. Carrier launch: the MQ-25 departs using the carrier’s catapult system.
  3. Hose deployment: the refuelling store reels out its hose and drogue at the planned location.
  4. Receiver approach: the receiving pilot stabilises behind the tanker and flies the aircraft’s probe into the drogue.
  5. Fuel transfer: fuel flows after a secure connection is made while both aircraft hold the required speed and formation.
  6. Disconnect and recovery: the receiver backs away, the hose retracts, and the MQ-25 returns for an arrested landing.

The delicate contact is flown by the receiver pilot; the tanker’s job is to maintain a predictable track and refuelling envelope. A boom-equipped receiver cannot take fuel from the MQ-25’s drogue unless that aircraft also has a compatible probe.

How does an uncrewed MQ-25 operate on an aircraft carrier?

The MQ-25 is designed to use the same basic launch-and-recovery environment as other carrier aircraft, but automation and shipboard control systems replace the pilot in the cockpit. Its wings fold to reduce the space it occupies on deck and in the hangar.

Deck crews still have to move, park and connect the aircraft safely among people, jet blast, catapults and arresting wires. Dedicated deck-control equipment allows authorised personnel to direct the aircraft during ground handling. Once airborne, human operators monitor the mission while automated flight systems execute assigned tasks.

“Uncrewed” therefore does not mean uncontrolled or independently roaming. Readers unfamiliar with the shipboard equipment can see how carrier catapult launches and arrested recoveries work.

How much extra range does the MQ-25 provide?

There is no single range increase that applies to every receiver or mission. The Navy’s widely stated design objective is associated with delivering 15,000 lb of fuel about 500 nautical miles from the carrier, but that is an offload target at a specified distance—not a promise that every fighter gains a fixed number of miles.

Useful fuel offload changes with the tanker’s launch weight, route, altitude, weather, time on station, recovery distance and required reserve. The receiver’s remaining fuel, drag, weapons load, flight profile and amount it can accept then determine the actual increase in radius or endurance.

A mistake we see constantly is quoting fuel offload without its distance from the carrier. Fuel delivered nearby cannot be compared directly with the amount available after the tanker has flown hundreds of nautical miles and retained enough fuel for recovery.

Is the MQ-25 a fighter jet or armed combat drone?

No. The MQ-25 is not a fighter jet, and its defined primary mission is not autonomous strike or air-to-air combat. Its angular planform can make the Stingray aircraft look like a stealth combat drone, but appearance does not change the programme’s tanker requirement.

There is no standard publicly defined weapons mission for the MQ-25. Secondary sensors or later growth options should not be confused with an operational strike role, and “uncrewed” does not imply independent weapon or targeting decisions.

What has the Boeing MQ-25 demonstrated in testing?

Boeing’s T1 demonstrator first flew from a land base in 2019 and completed major aerial-refuelling demonstrations in 2021. It transferred fuel to an F/A-18F Super Hornet, an E-2D Advanced Hawkeye and an F-35C Lightning II.

T1 also took part in deck-handling trials aboard USS George H.W. Bush in 2021. Those trials showed that deck personnel could direct an aircraft without an onboard pilot around a confined carrier flight deck.

They did not constitute a carrier catapult launch, arrested landing or declaration of routine fleet service. T1 was a demonstrator, and operational fielding requires production-representative aircraft, carrier-system integration, receiver certification, trained units, maintenance support and formal Navy acceptance. Planned service dates quoted in older reports should be treated as schedules rather than proof that those milestones were completed.

How should the MQ-25 mission work in a flight simulator?

In a flight simulator, an MQ-25 add-on should be judged by its tanker and carrier functions rather than by the presence of a conventional cockpit. The real aircraft has no onboard flight deck, so a virtual cockpit may be a developer convenience rather than a realistic crew station.

For practising receiver skills, an AI or scripted MQ-25 can be more useful than a flyable model. The receiving aircraft must use probe-and-drogue equipment, and the simulator or add-on must support actual fuel transfer rather than merely displaying a hose.

  • No fuel after contact: check that both tanker and receiver use the same refuelling system and that the add-ons support each other’s transfer logic.
  • Probe will not connect: stabilise before moving into the basket; chasing it with large control inputs usually causes repeated misses.
  • Carrier launch or recovery fails: confirm that both the aircraft and carrier model support compatible catapult and arresting functions.
  • Mission feels like a fighter sortie: build the flight around tanker tracks, timing, offload limits and recovery reserves rather than weapons employment.

Our practical guide to aerial refuelling in flight simulators covers receiver positioning, compatibility and the differences between simplified and contact-based implementations.
