Navy’s MQ-25A Stingray Secures Milestone C Approval, Entering Initial Production

The U.S. Navy has officially granted Milestone C approval to the MQ-25A Stingray program, marking a critical transition from the engineering phase into manufacturing and deployment. Announced on May 19, 2026, by Acting Secretary of the Navy Hung Cao, this decision authorizes Low-Rate Initial Production (LRIP) for the world’s first fully integrated, carrier-based unmanned aerial vehicle (UAV).

Developed by Boeing, the MQ-25A is designed primarily to provide organic aerial refueling to the Carrier Air Wing (CVW). By taking over routine tanking duties, the Stingray will relieve manned F/A-18E/F Super Hornets, significantly extending the operational reach and lethality of U.S. Carrier Strike Groups. According to the official Navy press release, this milestone follows a highly successful test flight of a production-representative aircraft in late April 2026, which cleared the path for fleet introduction.

The transition to production represents a major technological leap for naval aviation, introducing a hybrid manned-unmanned model to the flight deck and setting the doctrinal foundation for future collaborative combat aircraft.

Overcoming Delays and Proving Capabilities

The Crucial April Test Flight

The Milestone C decision was heavily dependent on the successful first test flight of a production-representative MQ-25A Stingray, which took place on April 25, 2026. As detailed in the Navy’s release, the aircraft launched from Boeing’s facility at MidAmerica Airport in Mascoutah, Illinois, and completed a comprehensive two-hour flight.

During this flight, the UAV autonomously executed a digitally programmed mission plan. The demonstration included taxiing, takeoff, complex flight maneuvers, and landing. Furthermore, the aircraft successfully responded to commands from the Unmanned Carrier Aviation Mission Control System (UMCS) MD-5 Ground Control Station, proving its readiness for carrier integration.

This successful demonstration was vital for the program’s advancement. The MQ-25A had previously missed its originally scheduled Milestone C target in fiscal year 2023 due to technical and production delays. The Pentagon’s Director, Operational Test and Evaluation (DOT&E) had previously cited concerns over the program’s reliance on data from an early prototype rather than production-representative hardware. The April 2026 flight of the operational model effectively resolved these hurdles.

“Boeing is honored to work alongside our U.S. Navy partner in achieving this historic milestone in the MQ-25A Stingray’s development life cycle. We remain focused on getting this game-changing unmanned aircraft into the hands of the fleet and integrated into the carrier air wing.”

Production Contracts and Program Scale

Transitioning to Low-Rate Initial Production

With Milestone C secured, the Navy is moving rapidly to initiate manufacturing. According to program data, the Navy is expected to award an LRIP Lot 1 contract for three aircraft this summer. This upcoming contract will also include priced options for Lot 2, which covers three additional aircraft, and Lot 3, which covers five aircraft.

The financial scope of the MQ-25A program is substantial. The original Engineering and Manufacturing Development (EMD) contract, signed in 2018, was valued at $805 million for the design, development, and delivery of the first four Stingray aircraft. Moving forward, the Navy expects the total program to cost approximately $13 billion to procure a complete fleet of 72 aircraft.

“Unmanned refueling extends our reach against any adversary. Moving the MQ-25A Stingray to Milestone C and into production is arming our warfighters with a capability that increases the lethality of our Carrier Strike Groups. This is a decisive advantage that delivers our warfighters what they need to fight and win.”

Technical Specifications and Strategic Impact

Engineering for Endurance

To meet the demanding requirements of carrier-based aerial refueling, the MQ-25A is powered by a single Rolls-Royce AE 3007N engine. This engine features a high-bypass-ratio (5:1) architecture specifically designed for low specific fuel consumption, which is critical for enabling the long-endurance missions required of a fleet tanker. While its primary mission is refueling, the Navy notes that the MQ-25A is also equipped to conduct Intelligence, Surveillance, and Reconnaissance (ISR) missions, adding a secondary layer of utility to the Carrier Air Wing.

“The Rolls-Royce AE 3007N engine was integral to the successful first flight of the MQ-25A Stingray, which will greatly enhance the range and capability of the U.S. Carrier Air Wing. We are honored the U.S. Navy has, once again, put its trust in our proven, reliable family of high-performance AE engines for this critical new unmanned platform.”

Redefining Carrier Strike Range

The introduction of the Stingray addresses a critical operational bottleneck for the Navy. Currently, up to 20 to 30 percent of F/A-18 Super Hornet flight hours are consumed by “buddy tanking”, the practice of using manned fighters to refuel other fighters. By assuming this organic tanking mission, the MQ-25A will preserve the service life of the Super Hornet fleet and allow manned fighters to focus strictly on combat and strike missions.

Furthermore, the Stingray is designed to offload up to 15,000 pounds of fuel at a distance of 500 nautical miles from the aircraft carrier. This capability effectively doubles the strike range of manned aircraft, a crucial metric for modern naval operations.

AirPro News analysis

The Milestone C approval for the MQ-25A Stingray is more than just an acquisition checkpoint; it represents a fundamental shift in the geometry of naval warfare. By allowing aircraft carriers to project power from significantly further away, the Navy is directly addressing the growing threat of adversarial anti-access/area-denial (A2/AD) systems, particularly in contested environments like the Indo-Pacific. Furthermore, the Stingray serves as the vital pathfinder for integrating autonomous drones into the high-pressure, complex environment of carrier flight decks. The lessons learned from the MQ-25A’s deployment will inevitably shape the future of collaborative combat aircraft (CCA) and the broader integration of unmanned systems across the U.S. military.

This article is based on an official press release from L3Harris Technologies.

On May 20, 2026, L3Harris Technologies announced the operational readiness and international availability of its modular light attack and intelligence, surveillance, and reconnaissance (ISR) Military-Aircraft. Built upon the rugged foundation of the Air Tractor AT-802 crop duster, the platform is being fielded in two distinct variants: the OA-1K Skyraider II for the U.S. Air Force Special Operations Command (AFSOC) and the SKY RAIDER II INTERNATIONAL for allied nations.

According to the official press release, the aircraft is designed to deliver persistent, low-cost airpower in austere environments. By integrating advanced modular systems like the “Red Wolf” standoff cruise missile and “Green Wolf” electronic warfare suites, L3Harris aims to provide a highly adaptable platform for modern irregular warfare and counter-terrorism operations.

From Crop Duster to Special Operations Workhorse

The Armed Overwatch Program

The OA-1K Skyraider II originates from U.S. Special Operations Command’s (SOCOM) “Armed Overwatch” program. Awarded in 2022 as a $3 billion initiative, the program sought a cost-effective, crewed aircraft to replace the aging U-28A Draco fleet. The primary objective was to secure a platform capable of close air support, precision strike, and armed ISR in permissive, low-threat environments.

To meet these requirements, L3Harris utilized the Air Tractor AT-802U airframe, a civilian aircraft renowned for agricultural crop dusting and aerial firefighting. As noted in the company’s release, the airframe was selected for its extreme ruggedness, having accumulated over 1.6 million flight hours in harsh conditions. In early 2025, the U.S. military officially designated the aircraft the OA-1K “Skyraider II,” a nod to the legendary Douglas A-1 Skyraider that provided close air support during the Korean and Vietnam Wars.

Capabilities and Modular Integrations

The “Wolf Pack” System

The Skyraider II boasts significant endurance and payload capacities. According to L3Harris, the aircraft provides five to eight hours of persistent surveillance and strike capability with a 250-nautical-mile combat radius. It is equipped with up to 11 hardpoints, allowing it to carry a 6,000-pound combat loadout that includes AGM-114 Hellfire missiles, AGR-20 APKWS laser-guided rockets, and GBU-12 laser-guided bombs.

Furthermore, the aircraft features Short Takeoff and Landing (STOL) capabilities. It can operate from unpaved dirt runways or highways, requiring roughly half the distance of comparable medium-altitude ISR platforms. AFSOC is also testing the aircraft’s rapid deployability, ensuring it can be disassembled, loaded into a C-17 or C-5 cargo plane, and reassembled for combat within hours.

L3Harris heavily emphasizes the aircraft’s modular open systems architecture. This includes the “Red Wolf” kinetic strike system, a low-cost miniature cruise missile providing a standoff strike capability of over 200 nautical miles, and the “Green Wolf” electronic warfare system for detection and jamming. The platform also integrates WESCAM MX-Series electro-optical/infrared sensors for high-definition surveillance and laser designation.

“Our customers demand a lean, agile aircraft that can fly, take off and land anywhere, anytime, outfitted with a wide range of payloads… Bringing together Red Wolf and Sky Warden demonstrates the rapid reconfiguration and customization of key L3Harris capabilities,” stated Jason Lambert, President of ISR at L3Harris, in the press release.

Strategic Value and Cost Efficiency

Shifting the Financial Paradigm

A primary driver behind the adoption of the Skyraider II is its extreme cost efficiency. L3Harris advertises the operating cost at under $1,000 per flight hour. Even when fully burdened, AFSOC officials cite a cost of roughly $2,500 per flying hour. This stands in stark contrast to traditional fighter jets like the F-16, which cost between $22,000 and $27,000 per hour to operate.

“The OA-1K is one of the most affordable AFSOC platforms, which then frees up higher-end assets that are more costly, for other mission sets around the world… With rapid disassembly and reassembly, OA-1K can be loaded into mobility aircraft like a C-5 or C-17 for rapid worldwide deployment,” noted Lt. Col. Robert Wilson, AFSOC Armed Overwatch Requirements Branch Chief.

“Skyraider II represents not just a new platform, but a modular solution to our national security needs… It will redefine how we approach joint campaigning, crisis response and the evolving landscape of modern warfare,” added Lt. Gen. Michael Conley, Commander of AFSOC.

Production and Global Proliferation

Current Deliveries and Export Potential

As of the SOF Week conference in May 2026, L3Harris has delivered 18 OA-1K aircraft to AFSOC out of a contracted 45. Production is currently advancing at a rate of roughly one aircraft per month at the company’s Waco, Texas facility. AFSOC is targeting the fourth quarter of 2027 for the aircraft’s first combat deployment.

Internationally, L3Harris is actively marketing the SKY RAIDER II INTERNATIONAL variant. The company has secured export license approvals for more than 20 countries, pitching the $25 million aircraft to nations in Africa, the Middle East, South America, and Eastern Europe for border security, maritime patrol, and counter-drone operations.

AirPro News analysis

We observe a fascinating irony in the Armed Overwatch program: the U.S. military is effectively converting a civilian crop duster into a highly lethal, sensor-packed warplane to save billions of dollars. By integrating the “Red Wolf” cruise missile, L3Harris is transforming a slow-moving propeller plane into a long-range strike platform. This blurs the traditional lines between light attack aircraft and high-end bombers. Furthermore, the global proliferation of the SKY RAIDER II INTERNATIONAL could significantly alter the balance of power in smaller regional conflicts, granting allied nations access to U.S. special operations-tier airpower at a fraction of the cost of a modern fighter jet.

Frequently Asked Questions

What is the OA-1K Skyraider II based on?
It is a heavily militarized version of the Air Tractor AT-802U, an aircraft traditionally used for crop dusting and aerial firefighting.

How much does it cost to operate?
L3Harris states it costs under $1,000 per flight hour, with AFSOC citing a fully burdened cost of roughly $2,500 per hour. This is significantly cheaper than traditional fighter jets.

What is the “Red Wolf” system?
It is a low-cost miniature cruise missile that gives the aircraft a standoff strike capability of over 200 nautical miles, allowing it to engage targets from a safe distance.

The Canadian Forces Snowbirds will be grounded following their 2026 season, and will not return to the skies until the early 2030s, according to reporting by CBC News. The iconic military aerobatic flight demonstration team is officially retiring its aging fleet of CT-114 Tutor jets after decades of service.

Defence Minister David McGuinty announced the grounding on May 19, 2026, at 15 Wing Moose Jaw in Saskatchewan. The Royal Canadian Air Force (RCAF) plans to replace the legacy jets with the CT-157 Siskin II, a turboprop aircraft. This transition will create an operational gap of four to six years where Canada will be without an active Air-Forces aerobatic demonstration team.

The 2026 season will serve as a farewell tour for the historic Tutor jets. According to the provided research report, the final season will feature 27 shows and flybys across Canada and the United States, culminating in a final planned performance in Moose Jaw this fall.

The End of the CT-114 Tutor Era

A Legacy in the Skies

The CT-114 Tutor has been the exclusive Commercial-Aircraft of the 431 Air Demonstration Squadron since the team’s formation in 1971. Originally ordered by the military in 1961 as training aircraft, the jets began their demonstration career in 1967. Over the decades, the Tutors have performed an estimated 2,700 times for well over 140 million people across North-America, according to historical data cited in the research report.

However, maintaining the mid-1960s airframes has become an insurmountable challenge. Of the 191 Tutors originally ordered, only about 26 are believed to remain in the RCAF’s inventory or in storage today.

Accelerated Retirement Timeline

Military officials and aviation experts have warned for years that the Tutors were operating beyond their intended lifespan. In 2020, the RCAF initiated a life-extension program designed to keep the jets flying until 2030. According to CBC News, RCAF Commander Lt.-Gen. Jamie Speiser-Blanchet explained that while most upgrades were delivered, recent feasibility studies revealed severe age-related engineering challenges. These technical realities forced the military to move the retirement timeline forward from 2030 to 2027.

Transitioning to the CT-157 Siskin II

Procurement Strategy

To replace the aging Tutors, the Department of National Defence (DND) will procure the CT-157 Siskin II, which is the Canadian designation for the Swiss-made Pilatus PC-21 turboprop. The Siskin II is already on order for the RCAF’s Future Aircrew Training (FAcT) program. The government intends to negotiate an add-on to this existing contract to acquire the additional aircraft needed for the Snowbirds.

The Jet vs. Turboprop Debate

The shift from a classic jet to a modern turboprop represents a fundamental change in aircraft capabilities. The research report notes that the Tutor boasts a top speed of approximately 480 knots, whereas the Siskin II tops out at around 320 knots.

Aviation experts and former Snowbird pilots have expressed reservations about this transition, arguing that the significant drop in top speed and the visual and auditory differences of a propeller plane will alter the dynamic of the air show. In response to these concerns, the DND stated that modern turboprop trainers like the Siskin II are highly capable and aerobatic-rated. The department noted that the team’s future choreography will be specifically redesigned to highlight the new aircraft’s unique strengths.

Political and Local Reactions

Government and Opposition Responses

The multi-year grounding has sparked political debate regarding long-term defense spending and asset management. Prime Minister Mark Carney addressed the issue during an event in Quebec, emphasizing the necessity of the transition.

“I inherited a situation where the planes literally had come to the end of their lives.”

According to CBC News, Carney added that the Snowbirds remain a source of national pride and will resume operations once the new planes arrive. Meanwhile, Conservative opposition members have criticized the lengthy service gap, labeling the news “heartbreaking” and questioning whether the government could have compressed the timeline by accelerating the FAcT contract.

Impact on Moose Jaw

Despite the temporary loss of the airshows, the squadron will permanently remain based at 15 Wing Moose Jaw. Local officials and Tourism Moose Jaw have expressed cautious optimism. While the grounding is a blow to local tourism, the confirmation that the squadron and the broader pilot-training mission will remain at the base preserves the city’s long-term aviation identity.

AirPro News analysis

At AirPro News, we observe that the four-to-six-year operational gap for the Snowbirds underscores persistent, systemic challenges within Canadian military procurement. Transitioning a national demonstration team from a legacy jet to a turboprop platform is a pragmatic, cost-effective solution that aligns with modern training pipelines, but it carries inherent public relations risks.

The success of the Snowbirds’ return in the early 2030s will heavily depend on how effectively the RCAF can rebrand the team’s choreography to suit the Pilatus PC-21’s flight envelope. While the visceral thrill and roar of a jet flyby will be lost, the agility of a modern turboprop could introduce tighter, more technical aerobatic maneuvers that appeal to a new generation of airshow audiences.
