U.S. Navy Clears Boeing MQ-25A Stingray Carrier Tanker Drone for Low-Rate Production.

The U.S. Navy has cleared Boeing’s MQ-25A Stingray for low-rate initial production, a move announced by Acting Secretary of the Navy Hung Cao on May 19, 2026, that strengthens the combat reach and endurance of carrier air wings without adding another manned aircraft to the deck. By restoring dedicated aerial refueling capability to the carrier fleet, the MQ-25A allows F/A-18E/F Super Hornets to remain focused on strike, escort, and air-defense missions instead of sacrificing flight hours to tanker support.

The unmanned tanker recently completed its first operational test flight from Boeing’s MidAmerica St. Louis Airport facility, validating the program’s transition from development into deployable fleet capability. The Navy plans to procure up to 11 aircraft across the first three production lots, reflecting a broader shift toward integrating unmanned systems that expand carrier survivability, operational tempo, and long-range power projection in contested environments.

Boeing's MQ-25A Stingray has been cleared for low-rate initial production, moving the U.S. Navy closer to carrier-based unmanned aerial refueling that can extend the range and endurance of F/A-18E/F, EA-18G, E-2D, and F-35C aircraft (Picture source: Boeing Defense).

Milestone C is important because it authorizes the transition from Engineering and Manufacturing Development into production and deployment planning, but it should not be read as immediate fleet service. The approval means the Navy has judged the aircraft, production system, test evidence, and acquisition baseline mature enough to begin controlled manufacturing while flight-envelope expansion, carrier suitability work, mission-system verification, and operational test preparation continue. For Congress, the issue is not simply whether the MQ-25A can fly; it is whether Boeing and the Navy can now produce repeatable aircraft, integrate them safely into carrier flight-deck procedures, and avoid converting a tanker program into another prolonged concurrency problem.

In armament terms, the MQ-25A is unarmed in its approved Navy role. Its mission equipment is fuel, a probe-and-drogue refueling system, autonomous flight-control software, secure command-and-control links, and the sensors needed to operate in the carrier environment. The aircraft is 51 feet long, has a 75-foot wingspan when spread, folds to 31.3 feet for carrier storage, and is powered by one Rolls-Royce AE 3007N engine. Its commonly cited tanker requirement is to deliver about 15,000 pounds of fuel at 500 nautical miles from the carrier, which makes fuel offload, not kinetic payload, the measure of combat effect.

That distinction matters tactically. A carrier air wing has finite deck space, launch cycles, tanker stations, spare aircraft, and fighter service life. When Super Hornets carry buddy stores to refuel other aircraft, they consume flight hours and deck spots while not carrying their optimal combat load. An MQ-25A detachment can shift part of that burden to an unmanned tanker, improving the number of manned fighters available for strike packages, defensive counter-air patrols, suppression of enemy air defenses, and recovery support.

The autonomy architecture is also a central acquisition issue. During the April 25 first flight, Navy and Boeing Air Vehicle Pilots controlled the MQ-25A through the Unmanned Carrier Aviation Mission Control System MD-5 ground control station, which includes Lockheed Martin’s MDCX system; the aircraft autonomously taxied, took off, flew, landed, and responded to commands. The MQ-25 Air System and UMCS are the two main segments of the Unmanned Carrier Aviation program, and their integration must cover deck handling, taxi, launch, recovery, mission planning, command authority, and maintenance. This is why carrier suitability may be a larger risk than basic flight performance.

The program’s path explains why LRIP is being watched closely. The MQ-25A evolved from earlier Navy unmanned carrier aviation work, including the X-47B demonstration and the canceled UCLASS concept, before the service narrowed the requirement to a carrier-based tanker under CBARS. Boeing received an $805 million contract in 2018 for four Engineering Development Model aircraft, while the company-owned T1 test aircraft first flew in September 2019 and later demonstrated refueling with an F/A-18 Super Hornet, E-2D Hawkeye, and F-35C. Boeing also moved the first Navy EDM aircraft into its 300,000-square-foot Mascoutah production facility in March 2025 and completed the first operational aircraft taxi test in January 2026.

The schedule remains compressed relative to earlier expectations. Navy budget documents moved initial operational capability to 2029, with the first carrier deployment no longer expected in the near term; carrier availability and production manufacturing delays have been identified among the causes. The service has expected a roughly $13 billion program for 72 aircraft, while Rolls-Royce has described the current program of record as 76 aircraft plus spare engines, a difference that likely reflects how development aircraft and total inventory are counted.

Operationally, the MQ-25A should be viewed as a range-management aircraft, not a substitute for a long-range strike aircraft or a survivable reconnaissance aircraft. It can push refueling farther from the carrier, reduce Super Hornet tanker use, and support longer missions by F/A-18E/F, EA-18G, E-2D, and F-35C aircraft, but it will also require protected routing, reliable communications, and disciplined deck-cycle planning. For the U.S. Navy, the LRIP decision is therefore a practical step: it begins building the aircraft needed for testing, training, and early fleet use while exposing whether the industrial base can deliver at the rate needed for future carrier deployments.
