Retirement of UH1N Huey Helicopters at Yokota Air Base in 2025
The UH-1N Huey helicopters retire from Yokota Air Base in 2025, impacting medevac and VIP missions amid budget and modernization challenges.
Introduction: The End of an Era at Yokota Air Base
The retirement of the UH-1N Huey helicopters from Yokota Air Base in August 2025 marks the close of a storied chapter in U.S. Air Force history in Japan. For nearly half a century, the distinctive sound of the Huey’s rotors echoed across the Tokyo metropolitan area, symbolizing both the American military presence and the enduring partnership between the United States and Japan. As the Air Force phases out the last of these Vietnam-era workhorses, the transition highlights not only the evolution of military technology but also the complex challenges of modernization, budgeting, and alliance management in a rapidly changing security environment.
This milestone is significant for multiple reasons. The Huey’s departure leaves a gap in critical missions such as medical evacuation, VIP transport, and disaster response, roles that have been vital to U.S. operations and regional stability. The uncertainty over replacement military-aircraft, complicated by budgetary pressures and shifting priorities, exposes broader questions about the sustainability of U.S. military capabilities in the Indo-Pacific and the future of U.S.-Japan cooperation.
Understanding the legacy of the UH-1N at Yokota, the circumstances of its retirement, and the implications for both operational readiness and international relations provides a window into the broader dynamics of military transformation in the 21st century.
Historical Context and the Huey’s Legacy at Yokota
The Bell UH-1 Iroquois, better known as the “Huey,” is one of the most iconic helicopters in military history. Developed in the 1950s and first deployed during the Vietnam War, the Huey became synonymous with American air mobility, medical evacuation, and rapid troop transport. Over 16,000 Hueys and their variants were produced, making the family one of the most widely built military aircraft in history.
Yokota Air Base’s relationship with the Huey began in the early 1970s, first with the UH-1P and then the twin-engine UH-1N, which became a fixture in 1980. The 459th Airlift Squadron, the only UH-1N unit in the entire Indo-Pacific, has maintained these helicopters for over four decades. The squadron’s roots go back to World War II, where it earned distinction as a bombardment unit before shifting to airlift and support missions in the postwar era.
The Huey’s impact was especially profound in the field of medical evacuation. During the Vietnam War, helicopter medevac operations, dominated by the Huey, revolutionized battlefield medicine, cutting fatality rates among the wounded and setting a new standard for rapid response. At Yokota, the 459th Airlift Squadron continued this tradition, providing medevac services for U.S. personnel and their families throughout Japan and Southeast Asia.
“The UH-1N has been a symbol of reliability, resilience, and unwavering support to the mission,” 374th Airlift Wing official statement
The Final Flights and Community Impact
The retirement process culminated in August 2025, with the 459th Airlift Squadron conducting a ceremonial “fini flight” over Tokyo. The route traced by the last two Hueys included some of the city’s most iconic landmarks, such as the Roppongi district and Tokyo Skytree, before landing at the Akasaka Press Center, a frequent destination for VIP transport missions. The event drew a crowd of U.S. and Japanese personnel and marked the end of an era for the base and the local community.
Public displays, such as the “SEEEYUH! 1980-2025” banner at Yokota’s Japanese-American Friendship Festival, underscored the Huey’s integration into local culture. For many Tokyo residents, the sight and sound of the Huey overhead were a familiar part of daily life, symbolizing both reassurance and, at times, controversy due to noise and low-altitude flight complaints.
Indeed, the Huey’s presence was not always universally welcomed. Between 2017 and 2020, Japan’s Defense Ministry recorded 178 complaints about low-flying U.S. military helicopters in Tokyo, highlighting the delicate balance between operational necessity and community relations in a densely populated urban environment.
Operational Significance and the Challenge of Replacement
The 459th Airlift Squadron’s mission portfolio has been broad and critical. Its four UH-1N helicopters, alongside three C-12J Hurons, provided medical evacuation, VIP transport, search and rescue, and disaster relief. The unit’s medevac role was especially crucial, as Japanese hospitals can legally refuse treatment to foreigners, making U.S. military hospitals the primary option for American personnel in emergencies. The Hueys often cut hours off ground transport times for urgent medical cases.
VIP transport was another essential function, regularly supporting high-level diplomatic and military coordination between the U.S. and Japan. The helicopters’ ability to access central Tokyo and restricted sites like the Akasaka Press Center made them indispensable for official travel. The squadron also supported joint exercises and contingency operations throughout the Pacific, maintaining a high mission readiness rate despite the age of its aircraft.
However, replacing the UH-1N has proven difficult. The Air Force’s plan to introduce the Boeing MH-139A Grey Wolf, a modern helicopter based on the Leonardo AW139, has been scaled back dramatically. Originally intended to replace all UH-1Ns, the program has been reduced from 84 to just 42 aircraft, with priority given to nuclear missile field security in the U.S. This leaves Yokota and other overseas locations without a direct replacement, raising questions about future operational capability.
“The reductions were just about the overall budget of the Air Force and what we’re able to afford and what we’re not able to afford,” Andrew Hunter, Air Force Acquisition Executive
Budget Constraints and Strategic Trade-offs
Budget pressures have played a decisive role in the fate of the UH-1N at Yokota. The Air Force’s fiscal year 2026 proposal seeks to retire 340 aircraft across multiple platforms, including the last Hueys at Yokota, as part of a broader push to reallocate resources toward next-generation systems. The cost of maintaining the aging Huey fleet has risen, but remains competitive compared to newer platforms, roughly $4.67 million per aircraft in 2018, up from $3.89 million in 2011.
The dramatic reduction in MH-139 procurement triggered a Nunn-McCurdy breach, requiring a comprehensive program review due to increased per-unit costs. While the Grey Wolf offers significant performance improvements, greater speed, range, payload, and cabin size, the focus on nuclear security missions has left other operational needs unaddressed. Alternative solutions, such as contracting commercial medevac services or assigning UH-60 Black Hawks, are being considered but may not match the flexibility or cost-effectiveness of the Huey.
These decisions reflect a broader strategic logic: prioritizing modernization and high-priority missions at the expense of secondary but still vital capabilities. The risk is that gaps in areas like medevac and VIP transport could undermine operational readiness and alliance cooperation, especially in crisis scenarios.
International Relations and Alliance Implications
The retirement of the Huey at Yokota carries implications beyond immediate operational concerns. The helicopter’s visibility in Tokyo made it a symbol of the U.S.-Japan alliance, supporting not only military but also diplomatic engagement. The squadron’s regular flights facilitated high-level meetings, joint exercises, and disaster response coordination, reinforcing the bilateral relationship at multiple levels.
At the same time, the U.S. military’s exemption from Japanese aviation regulations, dating back to postwar agreements, has been a source of friction. Japanese officials and residents have called for greater adherence to local rules and transparency in flight operations, reflecting evolving expectations about the U.S. presence in Japan.
Japan’s own helicopter modernization, with the introduction of the Subaru UH-2 (a Bell 412 variant), highlights a parallel commitment to maintaining rotary-wing capabilities. The contrast between Japan’s investment in new helicopters and the U.S. drawdown at Yokota underscores differing national priorities and resource constraints. The loss of the Huey at Yokota comes at a time of heightened regional tensions, making alliance coordination and operational flexibility more important than ever.

Conclusion: Lessons and Future Directions
The retirement of the UH-1N Hueys from Yokota Air Base is more than a technical or logistical milestone, it is a reflection of the broader challenges facing U.S. military modernization and alliance management in the Indo-Pacific. The 459th Airlift Squadron’s exceptional record of service, achieved with aging aircraft and limited resources, demonstrates both the resilience of legacy systems and the dedication of the personnel who operated them.
As the Air Force pivots toward new technologies and strategic priorities, the loss of the Huey at Yokota raises important questions about the sustainability of critical but non-core missions. The gap left by the Huey’s departure will be felt in medical evacuation, VIP transport, and disaster response, missions that underpin not only operational readiness but also the credibility of the U.S.-Japan alliance. The challenge for policymakers and military leaders is to ensure that modernization does not come at the expense of essential capabilities and that alliance commitments remain robust in an era of fiscal constraint and strategic uncertainty.

First Permanently Assigned F-15EX Eagle II Arrives at Kadena Air Base
The first F-15EX permanently assigned to Kadena Air Base, Japan, arrived November 15, 2026, the next phase in replacing its F-15C/D fleet.
The first F-15EX Eagle II permanently assigned to Kadena Air Base, Japan, arrived on November 15, 2026, making Kadena the first overseas U.S. Air Force installation to receive combat-coded F-15EX aircraft. The arrival marks the next phase in replacing the base’s legacy F-15C/D fleet, which a 2024 Department of Defense plan sets at 36 F-15EX aircraft in place of 48 F-15C/Ds.
The 18th Wing announced the arrival in a news release from its public affairs office, calling it a major milestone in the wing’s fighter modernization. Kadena becomes the second Air Force location to field the fighter, after the Oregon Air National Guard’s 142nd Wing at Portland Air National Guard Base.
Brig. Gen. John Gallemore, 18th Wing commander, tied the aircraft to the U.S.-Japan Alliance.
“The arrival of the F-15EX at Kadena marks a significant milestone for American airpower in the Pacific. These aircraft strengthen our ability to deter aggression, respond to emerging threats, and defend Japan alongside our allies and partners.”
Gallemore said in the release that the aircraft’s permanent presence at Kadena reinforces the U.S. commitment to the alliance and brings advanced combat capabilities to one of the most strategically important regions in the world.
Squadrons and maintainers trained away from home
According to the 18th Wing, operators from the 67th Fighter Squadron traveled to Eglin Air Force Base, Florida, and Portland Air National Guard Base, Oregon, to maintain flying proficiency and complete aircraft qualification training before the jet arrived. “Getting the F-15EX to Kadena is just the beginning,” said Lt. Col. Ajay Dua, 67th Fighter Squadron commander. Dua said the squadron’s focus now shifts to integrating the aircraft into its flying operations, building experience and learning how to get the most out of its capabilities.
Maintenance personnel from the 18th Aircraft Maintenance Squadron spent years preparing for the transition, working with Boeing and Air Force teams at Eglin and Portland to build and keep technical proficiency. They also supported F-15E operations at Shaw Air Force Base, South Carolina, during a personnel shortfall. “The arrival of the F-15EX represents years of hard work and dedication from our maintainers,” said Maj. Spencer Sherman, 18th Aircraft Maintenance Squadron commander.
Kadena had also hosted the type on visits before the permanent arrival. On June 29, 2026, an F-15EX returned to Kadena with two F-15E Strike Eagles, all three assigned to the 85th Test and Evaluation Squadron at Eglin, following an earlier inaugural visit. The 18th Wing said at the time that the visit helped validate maintenance procedures, logistics requirements and combat generation capabilities for future F-15EX operations, and it identified the 67th Fighter Squadron as Kadena’s first operational F-15EX unit.
From the 2024 basing plan to a permanent jet
The Department of Defense (DoD) announced the Kadena change on July 3, 2024, working closely with the Government of Japan, as part of a plan to upgrade U.S. tactical aircraft at several installations in Japan. The DoD said the plan reflects more than $10 billion in capability investments. Alongside the Kadena transition, it raises the Air Force presence at Misawa Air Base from 36 F-16s to 48 F-35As. The DoD said the Joint Force would keep a rotational presence of fourth- and fifth-generation tactical aircraft at Kadena throughout the transition.
The 18th Wing said Kadena’s F-15C/D fleet began its phased withdrawal in November 2022 after more than four decades of service. Rotational deployments kept a continuous fighter presence at the base in the meantime, among them an F-35A rotation from Alaska by the 356th Expeditionary Fighter Squadron, deployed from Eielson Air Force Base under the Air Force fighter rotation program.
The first Kadena-bound F-15EX was routed through Oregon. On August 28, 2026, the 18th Wing said the first F-15EX assigned to Kadena had left Boeing’s St. Louis facility for Portland Air National Guard Base, where it would receive more preparation before moving on to Kadena. At that point the wing said F-15EX arrivals at Kadena were scheduled to begin in fiscal year 2027. “This is an important next step toward bringing the F-15EX home to Kadena,” Gallemore said in August.
What the F-15EX adds at Kadena
The 18th Wing said the F-15EX brings advanced avionics, modernized electronic warfare systems and increased weapons-carrying capacity to Kadena’s fighter mission. The wing said the aircraft expands Kadena’s ability to conduct counterair operations while complementing fifth-generation aircraft and supporting bilateral readiness with the Japan Air Self-Defense Force (JASDF) and other regional partners. In August, the wing noted that it regularly trains with JASDF F-15s at Naha Air Base in bilateral exercises.
The arrival follows the latest F-15EX production award. On September 29, 2026, Boeing said the Department of War had awarded it a $2.38 billion contract for 22 more F-15EX aircraft, bringing the total under contract for Lots 1 through 7 to 120, as AirPro News reported in its coverage of the $2.38 billion award for 22 jets. Boeing said it would work with the Air Force and the Department of War to raise F-15EX production to two aircraft per month.
What comes next for the 18th Wing
The 18th Wing’s release does not give a schedule for the rest of the 36 aircraft. Both the 44th and 67th Fighter Squadrons will operate the F-15EX at Kadena, carrying forward the legacy of the two squadrons. The arrival also comes as the wing prepares for its centennial in 2027, marking 100 years since its activation as the 18th Pursuit Group at Wheeler Field, Hawaii, on January 21, 1927.

France Picks SDTS, Babcock and Top Aces for Red Air Combat Training
France selected SDTS, Babcock France and Top Aces France to fly A-4N, Alpha Jet and L-39 Red Air training in a deal worth up to €450 million.
France’s Armed Forces Commissariat Service (SCA) has selected SDTS, Babcock France and Top Aces France to fly privately operated A-4N Skyhawks, Alpha Jets and L-39s as Red Air adversaries for French combat units. Top Aces puts the contract’s total value at up to €450 million for the three partners, over an initial six years with an optional two-year extension.
Babcock International announced the award on November 3, 2026, describing an eight-year contract with the SCA under which it will provide adversary training with SDTS and Top Aces France to combat units of the French Air and Space Force, Navy and Army. Top Aces followed with its own press release on November 9, 2026, saying the French Ministry of the Armed Forces and Veterans, acting through the Armed Forces Commissariat, selected a consortium led by SDTS with Babcock France after a competitive process.
Who flies what
The two announcements describe the division of work in slightly different terms. According to Babcock, it will maintain and operate its own fleet of upgraded L-39 aircraft from its Dijon-Bourgogne base, while SDTS will maintain and operate A-4N Skyhawk Advanced Aggressor Fighter and Alpha Jet aircraft supplied by Top Aces France.
Top Aces said its wholly owned subsidiary, Top Aces France SAS, will supply the upgraded A-4N Skyhawks, fitted with systems and sensors that simulate advanced air threats, along with the Alpha Jets. The company said French nationals will fly the aircraft through Top Aces France, working with SDTS and Babcock France, and that the fleet will operate across France so that training takes place close to the participating units.
Sorties, airspace and JTAC work
Babcock said the contractor aircraft will fly alongside the French Ministry of the Armed Forces’ Rafale and Mirage 2000 fleets in French airspace. Missions will start from military air bases and civilian airports across France, with up to 400 training sorties and more than 1,000 flying hours each year.
The L-39s will carry Remotely Operated Video Enhanced Receiver (ROVER) technology, which allows real-time video exchange between pilots and ground controllers. Babcock said training will range from basic visual-range air combat maneuvers to Joint Terminal Attack Controller (JTAC) training, aimed at improving controllers’ ability to coordinate air and ground fires, share tactical information, protect friendly forces, identify and designate targets and keep situational awareness.
Neither company has disclosed how many aircraft of each type are assigned to the contract, which air bases and airports beyond Babcock’s Dijon-Bourgogne base will host them, or when the first sorties will be flown.
What the companies said
Pierre Basquin, Chief Executive Aviation and CEO of Babcock France, called the contract “an important milestone for Babcock France,” saying the work prepares aircrew and military personnel “for complex, high-intensity missions.” He said Babcock is “proud to contribute to maintaining the operational readiness that is essential to mission success.”
Paul Bouchard, Chief Executive Officer of Top Aces Inc., said the company is “honoured to partner with SDTS and Babcock France” and that the award reflects “the growing demand among European allies for dedicated, high-quality adversary air capabilities.” Didier Toussaint, Top Aces’ Group President, International, said: “This contract represents an important milestone for Top Aces in France.”
Three operators with different French footprints
Top Aces
Top Aces was founded in 2000 by veteran Royal Canadian Air Force CF-18 pilots and has regional headquarters in Montreal, Hermannsburg in Germany and Mesa, Arizona. The company describes itself as operating the world’s largest fleet of commercially owned tactical fighter aircraft, including the only privately operated F-16s, and reports more than 160,000 accident-free hours. It also owns Blue Air Training, which it describes as a leader in close air support training.
Top Aces said the French award is its second long-term contract with a European NATO ally in 2026, after the renewed 10-year contract with the Bundeswehr, worth up to €420 million, earlier in the year.
Babcock France
Babcock describes the Red Air award as a strategic step into operational readiness and combat training support. Its website also describes the Jet Pilots Modernised Training Programme, formerly known as FOMEDEC, which Babcock delivers for the French Air Force at Cognac airbase. The programme page lists 17 twin-seat Pilatus PC-21 turboprop aircraft and an annual volume of 11,000 flight hours and 6,500 simulator hours under an 11-year contract.
On December 4, 2025, Babcock announced a contract supplying an L-39 to EPNER, the French test pilot school, with the aircraft also to serve in adversary simulation roles for flight testing. Basquin said at the time that the deal “paves the way for further opportunities,” particularly “in operational training and the training of international pilots.” Babcock’s November 3 announcement presents the new award as support for the operational training of combat units.
SDTS
SDTS, which Top Aces names as the consortium leader, is based in Saint-Gilles, France. Its website lists eight Aermacchi MB339 C jets and one CTSW microlight for its air-to-air and Red Air missions, says its pilots come from the French Air and Space Force or the French Navy, and describes towed aerial targets for air-to-air weapons training. Neither announcement mentions the MB339s as part of the new contract.
How the contract value is framed
The €450 million figure is a ceiling that covers all three partners, and neither company has given a split between them. Top Aces lists the expected duration of the contract and the combined revenue the partners will earn from it among the forward-looking statements in its release, which it says depend on estimates and assumptions and carry significant uncertainty.
The term is also described in two ways. Top Aces gives an initial six years with an optional two-year extension, while Babcock refers to an eight-year contract with the SCA.

AEVEX Wins Nearly $400 Million IDIQ for Unmanned Aircraft Systems
AEVEX says an unnamed U.S. customer gave it a multi-year IDIQ with a ceiling of nearly $400 million for unmanned aircraft systems.
AEVEX Corp. has been awarded an Indefinite Delivery/Indefinite Quantity (IDIQ) contract with a ceiling of nearly $400 million to supply unmanned aircraft systems (UAS) and associated support services to an unnamed U.S. customer, the company said on November 10, 2026. For scale, the Solana Beach, California, company reported funded backlog of $259.8 million at June 30, 2026; the new figure is a ceiling, and the announcement does not say how much has been ordered under the contract.
In a press release dated November 10, 2026, AEVEX said the multi-year award establishes a flexible contracting framework that lets the customer procure UAS and associated support services across a range of mission needs. The announcement came one day before the company’s scheduled third-quarter 2026 results.
What the IDIQ award covers
AEVEX said the contract validates growing demand for adaptable, scalable UAS capabilities and reinforces its role as a U.S.-based provider of mission-focused technology and engineering expertise. The company said it develops, produces and supports UAS designed for affordability, modularity and rapid fielding.
“This award deepens our role in helping customers field unmanned aircraft systems that can be manufactured at scale and adapted as mission needs evolve,” said Roger Wells, Chief Executive Officer at AEVEX.
Wells said in the release that the IDIQ positions AEVEX to support customers as they advance initiatives aimed at accelerating UAS capability development and more agile acquisition models.
The release leaves several questions open for operators and suppliers tracking the award. It does not identify the customer or the agency behind the award, give a period of performance beyond describing the award as multi-year, say whether other companies hold awards under the same vehicle, or disclose the value of any initial task order. It names no aircraft type and gives no quantities.
AEVEX’s position after its stock market listing
AEVEX describes itself as a U.S. defense technology company that delivers autonomous unmanned systems, AI-enabled mission software, and intelligence, surveillance and reconnaissance (ISR) and electronic warfare solutions to national security customers. In its initial public offering announcement, the company listed headquarters in Solana Beach with additional facilities in California, Florida, Ohio, Virginia and Alabama, and offerings that include UAS, what it called combat-proven loitering munitions, and multi-mission unmanned surface vehicles.
AEVEX priced its offering on April 16, 2026, at 16,000,000 Class A common shares at $20.00 each, with trading on the New York Stock Exchange (NYSE) under the ticker AVEX expected to begin on April 17, 2026, according to the company’s pricing announcement. The pricing followed the IPO plans AirPro News covered earlier in April. The company is a portfolio company of Madison Dearborn Partners’ funds, the announcement said.
In its second-quarter 2026 results, released on August 12, 2026, AEVEX reported revenue of $201.8 million, against $101.1 million a year earlier. Its Tactical Systems segment brought in $174.2 million, which the company said was driven by UAS products and support services; the results release cites $72.2 million from the EUCOM AOR Deep Strike program. Funded backlog fell to $259.8 million at June 30, 2026, from $503.1 million at December 31, 2025, which the company attributed mainly to revenue recognized on that program. AEVEX raised its full-year 2026 outlook to revenue of $700.0 million to $720.0 million.
A run of unmanned awards and what comes next
The new IDIQ follows a series of smaller awards that AEVEX has announced in 2026. Its second-quarter awards included an $18.5 million U.S. Air Force award for UAS delivery and engineering services and $50 million from the U.S. Air Force for advanced unmanned mission capabilities. In August 2026, the company announced a $41 million award to support U.S. government customers in delivering one-way attack systems, and on September 9, 2026, it announced $20.5 million in new awards to deliver and further develop one-way attack system capabilities for U.S. government customers.
On September 23, 2026, AEVEX announced its jet-powered Specter attack platform, a turbojet-powered one-way attack system still under development with advanced manufacturing company Divergent. The company said Specter will have ground-launched and air-launched variants and a modular, swappable nose section for kinetic, non-kinetic, electronic warfare and ISR payloads.
AEVEX said it will release third-quarter 2026 results after the close of U.S. financial markets on Wednesday, November 11, 2026, and hold a conference call at 5:00 p.m. Eastern Time that day. Wells and Chief Financial Officer Todd Booth are scheduled to present at the Baird Global Industrial Conference in Chicago on November 12, 2026. The IDIQ release does not say when the first orders under the contract are expected.
