Final A-10 Engine Build Marks End of Davis-Monthan Maintenance Era
Davis-Monthan AFB completes last A-10 engine build as USAF extends aircraft service life through 2030, ending a 50-year maintenance mission.

This article is based on an official press release from Air Combat Command.
On May 21, 2026, Airmen at Davis-Monthan Air Force Base in Arizona officially completed their final A-10 Thunderbolt II engine build. According to an official release from Air Combat Command, this milestone marks the end of a decades-long maintenance mission for the 355th Component Maintenance Squadron (CMS) and serves as a symbolic closing chapter for the base’s 50-year legacy with the iconic close-air-support aircraft.
While the U.S. Air-Forces recently announced a partial extension of the A-10’s operational life through 2030, the formal training and heavy maintenance pipelines, including the dedicated Davis-Monthan engine shop, are officially shutting down. As the military transitions to future platforms, the completion of this final General Electric TF34 turbofan engine represents the end of an era for the maintainers who kept the “Warthog” flying.
We at AirPro News have reviewed the official military releases and supplementary research to provide a comprehensive look at what this final build means for the U.S. Air Force, the maintainers on the ground, and the future of the A-10 fleet.
A Historic Final Build for the 355th CMS
A standard A-10 engine build is a rigorous, multi-stage operation that typically takes 30 days to complete. The process involves meticulous inspection, repair, rebuilding, and testing of the General Electric TF34 turbofan engines that power the A-10C Thunderbolt II. According to military reports, a single crew of five maintainers usually handles the entire process for a given engine.
Hands-On Participation
For this historic final build, the 355th CMS broke from tradition. Every member of the shop participated, ensuring that all personnel had the opportunity to put their hands on the final engine throughout its diagnostic runs and final inspection. The final engine test was successfully conducted in the test cell on April 30, 2026, verifying its performance and flight readiness.
The process officially concluded on May 21, 2026, when Tech. Sgt. Logan Lamb, a 355th Maintenance Group quality assurance inspector, stamped the final inspection form. Wing leadership and the 355th CMS gathered to celebrate the completion, reflecting on the gravity of their work.
“Some, if not all these engines have saved lives on the ground through close air support missions, and some have carried pilots home while the other engine was damaged. All members of the shop put eyes and hands on this engine throughout the build, testing, diagnostic runs and final inspection. Typically, only one crew of five would work on any one engine, but this engine has been touched by everyone.”
The Warthog’s Legacy and Future Operations
Davis-Monthan AFB has served as the primary hub for A-10 operations and training for nearly 50 years. However, the base began divesting its A-10 fleet in February 2024, sending the first aircraft to the 309th Aerospace Maintenance and Regeneration Group, commonly known as the “Boneyard.” On April 3, 2026, the 357th Fighter Squadron at Davis-Monthan graduated its final class of A-10 pilots, permanently closing the formal training pipeline for the aircraft.
Service Extension Through 2030
Despite the closures at Davis-Monthan, the A-10 will continue to fly. On April 20, 2026, Air Force Secretary Troy E. Meink announced that the Air Force will extend the service life of the remaining A-10 fleet through 2030, reversing a previous plan to retire the aircraft by 2029. According to defense reports, this decision was heavily influenced by the A-10’s recent combat performance in Operation Epic Fury, a U.S. campaign against Iran in late March and April 2026, where the aircraft successfully struck naval vessels and provided critical close air support.
AirPro News analysis
The decision to extend the A-10’s service life through 2030 while simultaneously closing its primary heavy maintenance and training facilities presents a unique logistical scenario. The Air Force is utilizing what it calls a “fleet management strategy.” Because the Davis-Monthan engine shop and the pilot “schoolhouse” are now closed, operational squadrons at bases like Moody AFB and Whiteman AFB will be operating on borrowed time. They will have to rely entirely on existing experienced personnel, stockpiled parts, and the durability of engines like the one just completed by the 355th CMS to sustain operations until the final retirement date. This strategy underscores the military’s confidence in the robust engineering of the TF34 engines and the meticulous groundwork laid by aerospace Propulsion Airmen over the past decades.
The Unsung Heroes of Aerospace Propulsion
The longevity and survivability of the A-10 Thunderbolt II are directly tied to the expertise of aerospace propulsion Airmen. These maintainers are responsible for ensuring the aircraft remains lethal and capable of returning pilots home safely, even after taking heavy fire.
Their daily responsibilities include conducting borescope inspections to identify internal engine issues early and prevent catastrophic failures. They also manage test cell operations, running the engines in a controlled environment while monitoring critical readings from a control cab to verify performance before the engine is ever attached to an airframe.
“I think the legacy of the A-10 is going to be remembered for generations. The A-10 will be missed here in Arizona.”
Frequently Asked Questions (FAQ)
What engine does the A-10 Thunderbolt II use?
The A-10 is powered by twin General Electric TF34 turbofan engines. These engines are renowned for their durability and ability to sustain damage while still bringing pilots home safely.
Why is the A-10’s service life being extended to 2030?
Air Force Secretary Troy E. Meink announced the extension on April 20, 2026, following the aircraft’s highly successful combat performance during Operation Epic Fury in early 2026. The extension reverses previous plans to retire the fleet by 2029.
Is Davis-Monthan AFB still training A-10 pilots?
No. The 357th Fighter Squadron at Davis-Monthan graduated its final class of A-10 pilots on April 3, 2026, officially closing the formal training pipeline for the aircraft.

EU Funds SHARP Project for Next-Gen Military Helicopter Engine
The EU allocated €25M to the SHARP consortium, 25 partners from 12 countries developing Europe’s next military helicopter engine by 2040.

The European Commission has allocated approximately €25 million through the European Defence Fund to back a multinational consortium developing the propulsion architecture for Europe’s next generation of military helicopters.
Announced on June 11, 2026, at the ILA Berlin airshow, the Sovereign High-performance Architecture for Rotorcraft Propulsion (SHARP) project brings together 25 partners from 12 European countries. According to a joint press release from Safran Helicopter Engines, MTU Aero Engines, and Avio Aero, the initiative will establish the technological foundation for the European Next Generation Helicopter Engine (ENGHE), which is targeted to enter service in 2040.
Addressing an aging military rotorcraft fleet
The SHARP initiative aligns with broader European defense goals to replace a rapidly aging fleet of military aircraft under the Next Generation Rotorcraft Capability (NGRC) and European Next Generation Rotorcraft Technologies (ENGRT) programs. The current European inventory includes approximately 1,800 transport helicopters and 600 combat helicopters, which currently average 20 years of age. By the 2040s, many of these aircraft will have been in service for over 50 years.
“In light of a continuously aging European fleet of military helicopters the need is obvious: From 2040 onwards, a large proportion of these rotorcraft will have to be replaced,” said Dr. Ottmar Pfänder, Chief Program Officer at MTU Aero Engines. “We joined forces across the continent to underline the importance of this technology program. It will further reinforce European sovereignty and strengthen the European supply chain.”
The funding will be used to develop scalable technological building blocks that can be adapted to various weight classes and mission profiles required by future European armed forces.
Collaborative framework and European sovereignty
The SHARP project builds upon the foundation of the EUropean Military Rotorcraft Engine Alliance (EURA), a 50/50 joint venture established in July 2024 between Safran Helicopter Engines and MTU Aero Engines specifically to develop the ENGHE. The consortium has now expanded to include Avio Aero, broadening the industrial base tasked with designing the new powerplant.
Safran Helicopter Engines CEO Cédric Goubet stated that the funding demonstrates Europe’s commitment to self-reliance and technological sovereignty for future military platforms, thanking the European Union and participating nations for their confidence in the consortium’s capabilities.
“SHARP marks an important milestone in the journey toward Europe’s next-generation rotorcraft engine and reinforces the value of collaboration in developing sovereign, high-performance propulsion technologies,” said Riccardo Procacci, CEO of Avio Aero. “We are proud to partner with EURA on this initiative, contributing within a fully European framework while leveraging Avio Aero’s well-established expertise and know-how.”
EURA CEO Wolfgang Gärtner confirmed that the joint venture is prepared to coordinate the multinational team to provide modern technologies to European forces.
AirPro News analysis
The €25 million European Defence Fund grant represents a critical early step in aligning Europe’s fragmented defense aerospace sector behind a single rotorcraft propulsion program. By formalizing the SHARP consortium now, the European Union is actively working to prevent the development of competing, incompatible national engine programs that have historically complicated European defense procurement and increased long-term maintenance costs. We view the inclusion of Avio Aero alongside the EURA joint venture as a strong indicator that the ENGHE program is successfully consolidating the continent’s primary propulsion manufacturers ahead of the 2040 target.

Boeing MQ-25A Stingray Aboard USS Nimitz at FLEETEX 250
Boeing’s MQ-25A T1 demonstrator appeared on USS Nimitz during FLEETEX 250, weeks after Navy LRIP approval.

The Boeing Company’s MQ-25A Stingray T1 demonstrator drone appeared aboard the USS Nimitz (CVN 68) in the Atlantic Ocean on June 25, 2026, sporting special commemorative markings for the United States’ 250th anniversary. The uncrewed aircraft was photographed alongside Boeing F/A-18E Super Hornets and a Grumman C-2A Greyhound during a multinational group sail event.
The deployment provides a visual representation of the United States Navy’s future carrier air wing as the MQ-25 program transitions into its next production phase. Boeing Defense and the Navy publicly released imagery of the static display on June 29, 2026.
FLEETEX 250 and commemorative display
The T1 prototype was painted in a plain gray livery and featured “250” and “Boeing Backs America” markings. In a statement released on the social media platform X, Boeing Defense noted that the display was intended to honor the nation’s semiquincentennial and offer a glimpse of future carrier operations.
The USS Nimitz hosted the drone during Fleet Exercise (FLEETEX) 250. A Navy spokesperson told TWZ that the exercise involved 25 other warships and aircraft from 13 partner and allied nations conducting structured training events at sea. The spokesperson confirmed the presence of the Boeing-owned T1 prototype on the flight deck.
Aviation analysts at The Aviationist observed that the drone lacked the Cobham Aerial Refueling Store (ARS) pod, which is typically mounted under the left wing for refueling operations. The T1 demonstrator has never taken off from or landed on an aircraft carrier and was transported aboard the USS Nimitz for the exercise. It remains unconfirmed whether the uncrewed aircraft actively participated in any operational drills or if its presence was strictly for static display and photo opportunities.
Program milestones and carrier transitions
The appearance of the T1 demonstrator follows several recent advancements for the MQ-25 program. The Boeing-owned prototype originally flew on September 19, 2019, and previously conducted flight deck handling and remote control system demonstrations aboard the USS George H.W. Bush in December 2021.
On April 25, 2026, the first production-representative MQ-25 completed its maiden flight from Boeing’s facility at MidAmerica Airport in Illinois. The following month, the Navy officially approved the uncrewed tanker program’s transition into Low-Rate Initial Production (LRIP).
The FLEETEX 250 exercise also marked a significant operational transition for the Navy’s legacy aircraft. On June 25, 2026, the Grumman C-2A Greyhound made its final catapult launch and arrested landing from a carrier aboard the USS Nimitz. The C-2A is anticipated to be fully retired later in the year.
AirPro News analysis
The static display aboard the USS Nimitz offers a stark visual contrast between the Navy’s past and its immediate future. Placing the MQ-25A Stingray next to the retiring C-2A Greyhound highlights the physical footprint required to integrate advanced uncrewed assets into the carrier air wing. While the T1 demonstrator’s presence was largely ceremonial for the 250th anniversary, the recent approval for Low-Rate Initial Production indicates that the logistical and operational challenges of deploying uncrewed tankers at sea are moving from theoretical testing to active fleet integration. We expect the focus to shift rapidly toward deck handling and maintenance procedures for the production-representative models in the coming months.

NATO Expected to Select Saab GlobalEye to Replace AWACS Fleet
NATO is set to announce the Saab GlobalEye as its E-3A Sentry replacement at the July 2026 Ankara summit, bypassing Boeing’s E-7 Wedgetail.

This article summarizes reporting by Reuters by Sabine Siebold and Tim Hepher.
The North Atlantic Treaty Organization (NATO) is preparing to select the Saab GlobalEye to replace its aging fleet of Boeing E-3A Sentry airborne warning and control system (AWACS) aircraft, marking a significant shift toward European defense procurement. The official announcement is expected during the upcoming NATO summit in Ankara, Turkey, scheduled for July 7 and 8, 2026.
According to reporting by Reuters, four sources familiar with the matter indicated that the alliance will pivot away from its previous intention to acquire the Boeing E-7 Wedgetail. The decision represents a major defense contract for Sweden-based Saab AB and a notable setback for The Boeing Company in the airborne early warning and control (AEW&C) market. Neither NATO nor Saab has officially commented on the pending announcement.
Transitioning from the E-3A Sentry
NATO currently operates a fleet of 14 Boeing E-3A Sentry AWACS aircraft. Based at Geilenkirchen Air Base in Germany, these aircraft have been in service since 1982 and are approaching the end of their operational lifespan. The Saab GlobalEye, which completed its first flight in 2018, utilizes a modified Bombardier Global 6000 or 6500 business jet airframe equipped with Saab’s Erieye extended-range radar system.
The Boeing E-7 Wedgetail fallout
The anticipated selection of the GlobalEye follows a series of procurement shifts regarding the Boeing E-7 Wedgetail. NATO had initially planned to purchase six E-7 aircraft to replace the E-3A Sentry fleet. The alliance abandoned this plan in 2025 after the United States Department of Defense (Pentagon) canceled its own procurement of 26 Wedgetails in favor of satellite-based surveillance networks.
U.S. Secretary of Defense Pete Hegseth indicated to Congress in May 2026 that the Pentagon is attempting to reinstate the E-7 into the budget following pressure from U.S. lawmakers. Despite these efforts, international momentum appears to be shifting toward the Swedish manufacturer. On May 27, 2026, Canadian Prime Minister Mark Carney announced that the Government of Canada had entered formal negotiations with Saab as the preferred supplier for its own AEW&C program, bypassing the Boeing platform.
AirPro News analysis
We view NATO’s expected selection of the Saab GlobalEye as a critical indicator of changing procurement dynamics within the alliance. Historically, NATO has relied heavily on U.S.-manufactured heavy surveillance platforms. The shift to a European-integrated system on a Canadian business jet airframe suggests a growing preference for diversified defense supply chains and potentially lower operating costs compared to commercial airliner-based platforms like the E-7. If confirmed at the Ankara summit, this contract will solidify Saab’s position as a primary competitor in the global AEW&C market while placing additional pressure on Boeing’s defense sector to secure international orders for the Wedgetail program.
