Powering the Future: Kratos and GE Aerospace Hit Key Milestone with GEK800 Engine
In the world of defense technology, progress is often measured in milestones. A recent announcement from Kratos Defense & Security Solutions and GE Aerospace marks one such critical achievement. The successful completion of altitude, durability, and limits testing for their GEK800 engine is more than just a technical validation; it represents a significant step forward in powering the next generation of unmanned Military-Aircraft. This development is pivotal as the U.S. military shifts its strategy towards a concept known as “affordable mass”, building a formidable fleet of effective, lower-cost unmanned systems to complement its traditional crewed fighters.
The GEK800 engine is specifically designed for this new era of air combat. It is poised to become the heart of advanced Unmanned Aerial Systems (UAS), cruise missiles, and, most notably, the U.S. Air Force’s high-priority Collaborative Combat Aircraft (CCA) program. These CCAs, often called “loyal wingmen,” are semi-autonomous Drones designed to fly alongside crewed jets, multiplying a mission’s capabilities without putting more pilots at risk. The success of this engine program is a direct enabler of this futuristic vision, promising a Propulsion system that meets the stringent performance and cost requirements necessary to build out a planned fleet of at least 1,000 CCAs.
This achievement is the fruit of a powerful strategic Partnerships, formally established in June 2025, that combines Kratos’s agile, rapid-development ethos with GE Aerospace’s century of propulsion expertise and high-rate production capability. The rigorous testing, conducted at Purdue University’s world-renowned Zucrow Laboratories, pushed the engine to its operational boundaries, proving its robustness and clearing a path toward mass production. This collaboration isn’t just building an engine; it’s forging a critical piece of the defense industrial base needed to maintain a technological edge in the years to come.
A Technical Triumph at a Premier Facility
The series of tests completed in late October 2025 were comprehensive and demanding. Conducted at Purdue University’s Maurice J. Zucrow Laboratories, the largest academic propulsion lab in the world, the GEK800 was subjected to a battery of trials designed to simulate real-world combat conditions. This included altitude testing to ensure performance in the thin air of high altitudes, durability trials to prove its reliability over time, and limits testing to intentionally push the engine to its breaking point. According to GE Aerospace, the joint team successfully identified the engine’s rotor speed limits and compressive system boundaries, validating its outstanding performance and durability.
The choice of venue was as significant as the tests themselves. The trials marked the inaugural use of the newly expanded ZL9 test facility at Zucrow Labs for an engine test of this nature. This state-of-the-art facility allowed the team to simulate the harsh environments the engine will one day operate in. The collaboration between Kratos, GE Aerospace, and the university’s experts was praised for its efficiency and technical excellence. Daniel Fineberg, the Kratos GEK800 Test Coordination Lead, noted that the joint team “successfully met nearly all test objectives while also validating the capability to conduct this style of testing within a newly commissioned facility.”
The GEK800 is an 800-pound-thrust class jet engine, a product of over a decade of initial development and ground testing by Kratos. The partnership with GE Aerospace, which began informally in 2023, has dramatically accelerated its progress, with over 50 engine starts completed during ground testing before this crucial altitude phase. The engine’s architecture is also designed for scalability, with plans for variants producing up to 3,000 pounds of thrust. A 1,500-pound-thrust version, the GEK1500, is already in development, demonstrating a clear roadmap for powering a wide range of future unmanned platforms.
“Successfully completing altitude testing marks a major milestone in the GEK800 engine program and demonstrates the strength of our partnership with GE Aerospace, AFRL, and Purdue University’s Zucrow Laboratories.” – Stacey Rock, President of Kratos Turbine Technologies.
Strategic Implications and the Dawn of “Affordable Mass”
The success of the GEK800 program extends far beyond the engineering lab. It is a cornerstone of the Pentagon’s evolving defense strategy, which emphasizes the concept of “affordable mass.” This doctrine calls for supplementing expensive, crewed fighter jets with large quantities of less expensive, “attritable” unmanned aircraft. These platforms are effective enough to be decisive in combat but affordable enough that their loss does not constitute a catastrophic strategic or financial blow. This approach aims to counter adversaries by leveraging numerical superiority and overwhelming their defenses.
The Kratos-GE Aerospace partnership is perfectly positioned to deliver on this vision. Kratos contributes over 25 years of experience in developing small, affordable engines, focusing on agile design and cost-effective solutions. GE Aerospace brings its unparalleled legacy in propulsion technology and, critically, the industrial might to scale advanced designs into high-rate production. This synergy bridges the notorious gap between a successful prototype and a mass-produced, field-ready product, a challenge that has often hindered defense innovation.
The primary application for the GEK800 is the Collaborative Combat Aircraft (CCA) program, a key component of the Air Force’s Next-Generation Air Dominance (NGAD) initiative. CCAs will act as force multipliers, controlled by pilots in nearby F-35s or future sixth-generation fighters. They can be tasked with missions like reconnaissance, electronic warfare, or carrying extra munitions, extending the reach and capability of the crewed fleet while keeping pilots safer. The viability of this entire concept hinges on the availability of reliable, affordable propulsion systems like the GEK800. The involvement of the Air Force Research Laboratory (AFRL) and the Office of Naval Research (ONR) further underscores the program’s significance to national defense.
Conclusion: A New Chapter in Aerial Warfare
The successful altitude testing of the GEK800 engine is a landmark achievement for Kratos and GE Aerospace, but its true significance lies in what it enables. This milestone validates a critical piece of technology required to bring the U.S. military’s vision for next-generation air combat to life. By proving the engine’s performance and durability, the program moves from the realm of development into the tangible path toward production, promising to power the fleets of unmanned systems that will define the future battlespace.
Looking forward, the scalability of the GEK engine family and the robust industrial partnership behind it suggest a sustained impact on the defense landscape. As the GEK800 moves closer to deployment, it will fuel the strategic shift towards “affordable mass,” fundamentally changing the calculus of air warfare. This engine is more than just a piece of hardware; it is an enabler of a new doctrine, a new generation of aircraft, and a new era of national security capability.

USAF Launches EPAWSS Speedline to Accelerate F-15E Modernization
The USAF establishes an EPAWSS Speedline at Warner Robins to rapidly upgrade F-15E Strike Eagles with advanced electronic warfare systems starting June 2026.
This article is based on an official press release from the Air Force Life Cycle Management Center.
Air Force Launches EPAWSS Speedline to Accelerate F-15E Modernization
On May 26, 2026, the Air Force Life Cycle Management Center (AFLCMC) announced the establishment of a dedicated “Speedline” facility at the Warner Robins Air Logistics Complex (WR-ALC) in Georgia. This new initiative is designed to rapidly accelerate the installation of the Eagle Passive Active Warning Survivability System (EPAWSS) on the U.S. Air Force’s F-15E Strike Eagle fleet.
According to the official press release, the Speedline facility is slated to receive its first F-15E aircraft for installation in June 2026. By decoupling these critical electronic warfare upgrades from standard Programmed Depot Maintenance (PDM) schedules, the Air Force aims to field advanced defensive capabilities much faster than previously possible.
We note that this shift in maintenance strategy allows the military to upgrade jets up to five to seven years ahead of their routine maintenance cycles. This collaborative effort between the AFLCMC’s F-15 System Program Office and the WR-ALC is expected to significantly boost fleet readiness against modern electromagnetic threats.
Breaking the Maintenance Bottleneck
Operational Independence
Historically, major system upgrades for fighter aircraft have been tied to their routine depot maintenance schedules, which can create bottlenecks for fielding urgent technology. The AFLCMC’s new Speedline operates entirely independently of the standard PDM line.
This operational independence provides the F-15 System Program Office and WR-ALC the flexibility to install the EPAWSS on aircraft that are not due for routine maintenance for another five to seven years. By treating the electronic warfare upgrade as a standalone priority, the Air Force can modernize its fleet at a pace dictated by tactical necessity rather than logistical routine.
Understanding the EPAWSS Upgrade
Replacing Cold War-Era Technology
The Eagle Passive Active Warning Survivability System is a next-generation, all-digital electronic warfare suite. Based on the provided research data, it is designed to replace the legacy Tactical Electronic Warfare System (TEWS), which relies on Cold War-era analog equipment.
Developed by prime contractor BAE Systems, with Boeing serving as the prime contractor for integration, EPAWSS provides fully integrated radar warning, geolocation, situational awareness, and self-protection solutions. The system allows the aircraft to detect, identify, and defeat surface and airborne threats in highly contested, dense signal environments.
Financial and Production Milestones
The U.S. Air Force officially cleared EPAWSS for full-rate production in early 2025. Concurrently, the Air Force awarded a $615.8 million contract to Boeing to cover the installation of these systems. Shortly after this award, the first fully equipped F-15E was delivered to the 48th Fighter Wing at RAF Lakenheath in the United Kingdom, marking a major milestone in the modernization of the 4th-generation fleet.
Strategic Importance and Lethality
Expanding the F-15E’s Capabilities
The integration of EPAWSS is not merely a defensive measure; it is a comprehensive upgrade to the aircraft’s survivability and lethality. In the official AFLCMC release, military leadership emphasized the strategic necessity of the system.
“The F-15E Strike Eagle remains a cornerstone of our tactical airpower and deep strike capabilities. The integration of advanced electronic warfare suites, such as the Eagle Passive Active Warning Survivability System, ensures the F-15E will not just survive, but actively disrupt and dismantle adversary kill chains in the most highly contested, electromagnetically dense environments.”
, Lt. Col. Matthew Heil, F-15 Program Office, EPAWSS Materiel Leader
AirPro News analysis
We observe that the creation of the EPAWSS Speedline reflects a broader Department of Defense trend toward agile logistics and sustainment. By separating critical combat upgrades from time-consuming depot maintenance, the military is demonstrating a commitment to fielding new technologies to the warfighter at a much faster pace.
Furthermore, as the U.S. Air Force continues to develop and field 5th-generation fighters like the F-35 and F-22, alongside future 6th-generation platforms, maintaining the survivability of 4th-generation “workhorse” aircraft is a strategic priority. EPAWSS ensures that older airframes like the F-15E can safely and effectively operate alongside stealth fighters in modern, highly contested combat scenarios, bridging the gap between legacy platforms and future air dominance initiatives.

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.

Airbus Explores Helicopter Manufacturing in Canada for Global Export
Airbus SE is evaluating manufacturing helicopters in Canada to support federal defense contracts amid Canada’s $81B defense investment and new industrial strategy.
This article summarizes reporting by Bloomberg and Laura Dhillon Kane. This article summarizes publicly available elements and public remarks.
According to reporting by Bloomberg, Airbus SE is evaluating the potential to manufacture helicopters in Canada for the global export market, provided the European aerospace giant secures upcoming federal procurement contracts. This strategic proposition arrives as Canada embarks on an unprecedented defense spending expansion aimed at modernizing its military and stimulating domestic manufacturing jobs.
We note that Airbus is leveraging a unique political and economic window. By pitching a “local for global” manufacturing approach, the company hopes to decentralize its production while satisfying the Canadian government’s increasingly stringent demands for domestic economic benefits in exchange for lucrative defense contracts.
Canada’s Historic Defense Spending Surge
Following years of underfunding, the Canadian government has recently injected an $81.1 billion multi-year investment into national defense, according to comprehensive industry research. Under the administration of Prime Minister Mark Carney, Canada officially reached the 2% NATO spending benchmark in March 2026 and has committed to escalating defense expenditures to 5% of GDP by 2035.
The 2026 Defence Industrial Strategy
A major catalyst for Airbus’s proposal is the Canadian government’s first-ever Defence Industrial Strategy (DIS), launched in February 2026. Research reports indicate that the DIS introduced a strict “Build-Partner-Buy” framework designed to maximize domestic economic activity. The strategy ambitiously aims to direct 70% of defense contracts to Canadian firms, create 125,000 jobs, and boost defense exports by 50%.
To win contracts under this new framework, foreign vendors are required to provide sustainable domestic economic activity and transfer intellectual property. Furthermore, Canada is actively seeking to diversify its defense procurement to reduce its historical reliance on U.S. suppliers, pivoting toward European partnerships and joining the EU’s €150 billion Security Action for Europe (SAFE) fund.
Airbus’s “Local for Global” Pitch
Airbus is no stranger to the Canadian aerospace sector, having operated in the country for over 40 years. According to industry data, the company currently employs over 5,300 people in Canada. Its helicopter division, based in Fort Erie, Ontario, is already a recognized center of excellence for composite manufacturing, shipping approximately 34,000 parts globally each year to support Airbus’s worldwide supply chain.
Targeting Key Government Contracts
Airbus is actively pursuing three major helicopter procurement projects in Canada: fleet replacements for the Canadian Armed Forces, the Canadian Coast Guard, and the Royal Canadian Mounted Police (RCMP). To bolster its position, Transport Canada officially certified the Airbus H175 helicopter in February 2026, a super-medium aircraft tailored for search and rescue and defense missions in harsh environments. Additionally, Airbus is currently delivering 19 H135 helicopters to the Royal Canadian Air Force for the Future Aircrew Training (FAcT) program.
Airbus executives have made it clear that winning these new contracts would justify expanding their Canadian manufacturing base to assemble complete helicopters for the global market.
“Clearly, if Airbus helicopters are selected for any of the big upcoming campaigns and there is an industrial project which is tied to this contract, it’s an opportunity to export what would be manufactured here to the worldwide market.”
“We see that the H175 is very well positioned for several of those ambitions… We really see that as an aircraft for Canada, but… it would also be a helicopter from Canada.”
Balancing Economic Demands with Aerospace Realities
While Airbus is willing to expand its manufacturing footprint, company leadership has cautioned against overly transactional government demands. Michalon noted that while Airbus can offer research, development, and local procurement, there are practical limits to quid-pro-quo arrangements in aerospace manufacturing.
“If you ask us, ‘Can you bring a car plant in exchange for us selecting [an Airbus helicopter]?’ the answer is ‘Probably not, no.'”
AirPro News analysis
We observe that Canada’s deliberate pivot toward European defense partnerships represents a significant geopolitical shift. Historically, over 90% of Canada’s military helicopters and 100% of its fighter aircraft have been sourced from the United States. While diversifying procurement builds sovereign capacity and integrates Canada into European supply chains, defense experts suggest it could introduce interoperability friction with U.S. forces, particularly concerning joint North American Aerospace Defense Command (NORAD) operations.
Furthermore, establishing a Canadian export hub would provide Airbus with much-needed supply chain redundancy. By decentralizing production from its primary plants in France and Germany, Airbus can better insulate itself from European supply chain bottlenecks. Canada’s 2025 entry into the NATO Next Generation Rotorcraft Capability (NGRC) initiative also positions the country as a long-term collaborator alongside European nations to manage the rising development costs of future military rotorcraft.
Frequently Asked Questions (FAQ)
Why is Airbus considering building helicopters in Canada?
According to Bloomberg reporting, Airbus is exploring Canadian manufacturing for global export as a strategic incentive to win upcoming federal procurement contracts for the Canadian Armed Forces, Coast Guard, and RCMP.
What is Canada’s current defense spending target?
Under Prime Prime Minister Mark Carney, Canada officially hit the 2% NATO spending benchmark in March 2026 and has committed to reaching 5% of GDP by 2035, backed by an $81.1 billion multi-year investment.
What is the Defence Industrial Strategy (DIS)?
Launched in February 2026, the DIS is a Canadian government framework aiming to direct 70% of defense contracts to domestic firms, create 125,000 jobs, and boost defense exports by 50% by requiring foreign vendors to invest locally.
