Japan’s SDF Destroyers: From Helicopter Carriers to Aircraft Carriers

Japan’s Maritime Self-Defense Force (JMSDF) is undergoing a significant transformation with the conversion of its Izumo and Kaga destroyers into de facto aircraft carriers. This move marks a pivotal shift in Japan’s defense strategy, enabling the operation of advanced F-35B stealth fighter jets. The decision reflects Japan’s evolving security needs in the face of regional tensions, particularly with China’s growing military presence in the East and South China Seas.

The Izumo and Kaga, originally classified as helicopter destroyers, were designed for anti-submarine warfare and disaster relief. However, their conversion into aircraft carriers signifies a strategic pivot towards enhancing Japan’s air defense capabilities. This development is not only a technological leap but also a symbolic shift in Japan’s post-World War II defense policies, which previously prohibited the operation of aircraft carriers.

Historical Context and Significance

The Izumo-class destroyers were first announced in 2009, with JS Izumo commissioned in 2015 and JS Kaga in 2017. These vessels were initially designed to carry helicopters, primarily for anti-submarine warfare. However, the changing geopolitical landscape in the Indo-Pacific region prompted Japan to reconsider their role. In December 2018, the Japanese Cabinet approved modifications to these ships to accommodate F-35B fighter jets, which are capable of short takeoff and vertical landing (STOVL).

Historically, Japan operated aircraft carriers during World War II, with the original Kaga being a prominent example. Post-WWII, Japan’s pacifist constitution and defense guidelines prohibited the operation of such vessels. The conversion of the Izumo-class ships represents a significant departure from these restrictions, reflecting Japan’s proactive approach to regional security challenges.

The conversion process involves several critical modifications to the Izumo and Kaga. These include reinforcing the flight decks to withstand the heat and forces generated by F-35B jets, reshaping the bow section from trapezoidal to rectangular, and installing necessary power supply equipment. These changes enable the ships to operate as full-fledged aircraft carriers, capable of launching and recovering advanced fighter jets.

Performance tests conducted in 2021 confirmed the feasibility of operating F-35Bs from JS Izumo, with similar tests on JS Kaga following in 2024. These milestones demonstrate the successful integration of cutting-edge technology into Japan’s naval fleet. The Japan Air Self-Defense Force has ordered 42 F-35B variants, with deliveries expected to begin in 2024. These aircraft will initially operate from land bases before transitioning to the Izumo-class ships.

The Izumo-class ships measure approximately 248 meters in length and have a standard displacement of 19,500 tons. With the conversion, they will be capable of carrying up to 28 aircraft, including F-35B jets and helicopters. This multi-role capability enhances Japan’s ability to respond to a wide range of security threats, from aerial combat to disaster relief.



Regional and Global Implications

The conversion of the Izumo-class ships is a strategic response to China’s growing military assertiveness in the Indo-Pacific region. By enhancing its naval capabilities, Japan aims to strengthen its deterrence and ensure regional stability. The cooperation with the U.S. Marine Corps in operating F-35Bs from these ships underscores the strong bilateral defense relationship between Japan and the United States.

This development also reflects broader trends in naval warfare, where versatility and multi-role capabilities are increasingly valued. The ability to operate advanced fighter jets from naval platforms provides Japan with a significant advantage in maintaining air superiority and responding to crises. The conversion of the Izumo-class ships aligns with Japan’s evolving defense policies, which emphasize proactive contributions to regional and global security.

Looking ahead, the completion of the second phase of modifications for JS Izumo and JS Kaga is expected by 2027 and 2028, respectively. These upgrades will further enhance Japan’s naval capabilities, ensuring that the JMSDF remains a formidable force in the Indo-Pacific region. The integration of F-35B jets into Japan’s naval fleet marks a new chapter in the country’s defense strategy, with far-reaching implications for regional security.

Conclusion

U.S. Customs and Border Protection Air and Marine Operations (CBP AMO) has finalized a contract to acquire 10 additional Airbus H125 helicopters, expanding a fleet modernization effort that relies heavily on the single-engine platform for border security and law enforcement missions.

In a press release issued on July 7, 2026, Airbus confirmed the agreement, which reinforces a three-decade relationship between the federal agency and the aerospace manufacturer. The new helicopters will be assembled at the Airbus Helicopters production facility in Columbus, Mississippi.

Expanding the airborne law enforcement fleet

The latest acquisition builds upon a previous order placed in August 2020, when CBP AMO contracted for 16 H125 helicopters to upgrade its aging rotary-wing assets. The agency currently operates a total fleet of more than 240 aircraft, which includes over 100 helicopters from the Airbus H120 and H125 families delivered over the past 30 years.

The H125, formerly known as the Eurocopter AS350, is utilized by CBP AMO for a variety of demanding flight profiles, including border surveillance, suspect pursuit, and general public safety operations across the United States.

Bart Reijnen, Head of the North America Region for Airbus Helicopters, stated that the expansion “underscores the long-standing collaboration” between the manufacturer and the federal agency. He added that the selection highlights the trust placed in the H125 to execute critical public safety missions under demanding conditions, with Airbus committing to provide comprehensive services to maintain mission readiness.

Virtual reality integration for pilot training

As CBP AMO increases its H125 inventory, the agency is simultaneously overhauling how it trains the personnel who fly them. In November 2025, CBP became the first federal law enforcement agency and the first branch of the U.S. Department of Homeland Security (DHS) to integrate virtual reality into its aerial training program.

According to reporting by FLYING Magazine, the agency awarded a contract to adopt an FAA-qualified Airbus H125 virtual reality flight simulator developed by Loft Dynamics. The simulator is being installed at the CBP AMO training center in Oklahoma City, where it will be used to train the agency’s roster of more than 600 pilots.

Published

on

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.
