Switzerland Extends F/A-18C/D Hornets Into 2030s to Secure Air Defence Continuity as First F-35A Enters Assembly.

Switzerland has completed the key work needed to keep its F/A-18C/D Hornet fighters operational into the early 2030s, ensuring uninterrupted air defence coverage as the country begins the transition to the F-35A, according to Swiss federal authorities on 1 June 2026. The move preserves air sovereignty and quick-reaction alert capability during a critical period in which the first Swiss F-35A has already entered main assembly in the United States, reducing the risk of any gap in national airspace protection.

The Hornet life-extension program upgrades mission systems, communications, training infrastructure, and structural components, allowing the fleet to remain combat-ready while Switzerland prepares personnel and support networks for fifth-generation operations. As 36 F-35As enter service between 2027 and 2030, the Swiss Air Force will gain enhanced situational awareness, sensor fusion, and digital combat capabilities, reflecting the broader shift toward data-driven air defence and future warfare.

On 1 June 2026, Swiss federal authorities announced the completion of the principal work required to extend the operational life of the Swiss Air Force’s F/A-18C/D Hornet fleet. The announcement came only days after confirmation on 28 May 2026 that main assembly of Switzerland’s first F-35A fighter aircraft had commenced in the United States. Together, these developments represent a significant milestone in the modernization of Swiss military aviation, balancing the sustained availability of a proven fourth-generation combat aircraft with the gradual introduction of a fifth-generation platform.

The parallel progression of both programs reflects a carefully managed transition strategy aimed at preserving Switzerland’s air defense capabilities throughout the modernization process. By extending the service life of its Hornet fleet while preparing for the arrival of the F-35A, Switzerland seeks to maintain uninterrupted air sovereignty missions, ensure the continuity of quick reaction alert operations, and avoid any capability gap during the replacement of its combat aircraft fleet. Beyond the acquisition of new platforms, this approach underscores a broader effort to guarantee operational readiness and national airspace protection during a pivotal period of force renewal.

The Swiss F/A-18C/D Hornet fleet has served as the backbone of national air defence since 1997, providing the Swiss Air Force with a supersonic, multirole combat aircraft able to conduct air policing, interception, air defence training and operational readiness missions in a demanding geographic environment. Its extension into the early 2030s reflects a practical and disciplined approach to fleet management. For Switzerland, where air policing is a sovereign mission conducted over a compact, mountainous and highly regulated national airspace, the availability of a credible fighter fleet during the transition remains central to daily defence readiness. The Hornet remains a critical operational bridge until the F-35A reaches sufficient availability within the Swiss Air Force.

The useful life extension was launched under the 2017 Armed Forces Dispatch with an approved amount of CHF 450 million. The programme included the introduction of modernised communication, navigation and identification systems, aircraft software modifications, mission planning system updates and flight simulator adaptations. These elements are essential in modern air operations, where the effectiveness of a fighter fleet depends not only on airframe performance, propulsion and weapons compatibility, but also on secure identification, cockpit software reliability, training fidelity and the ability to integrate with national command-and-control procedures. In this sense, Switzerland’s decision demonstrates a preference for controlled modernisation, operational continuity and responsible use of defence resources.

A central part of the work concerned the inspection and renovation of selected aircraft structural components. Completed at the end of April 2026, this subproject was required to preserve airworthiness across all 30 Swiss F/A-18C/D aircraft up to 6,000 flying hours per airframe. Such structural work is particularly important for fighter aircraft exposed to repeated manoeuvre loads, high-speed flight profiles, training cycles and the long-term fatigue effects associated with operational service. By extending the structural life of the Hornet fleet, Switzerland has secured the necessary margin to continue air defence missions while giving the Swiss Air Force time to prepare personnel, infrastructure, maintenance processes and training pipelines for the introduction of the F-35A.

The timing is significant because the first Swiss F-35A has now entered main assembly at Lockheed Martin’s facility in Marietta, Georgia. In the coming months, the aircraft will pass through further production and assembly stages before supporting the first Swiss training phase in the United States. The first eight Swiss F-35A aircraft are scheduled to be deployed from mid-2027 at Ebbing Air National Guard Base in Arkansas for pilot training, while the first aircraft are expected to arrive in Switzerland from mid-2028. The remaining Swiss F-35A aircraft will be delivered from the final assembly line in Cameri, Italy, providing a phased pathway from training and conversion to national basing and operational integration.

Switzerland’s F-35A acquisition was contractually agreed in 2022 for 36 aircraft, with deliveries planned between 2027 and 2030. The aircraft will replace both the F/A-18 Hornet and F-5 Tiger fleets, allowing the Swiss Air Force to consolidate its future combat aviation around a single modern platform. This consolidation is relevant from an operational and logistical perspective, as it simplifies fleet planning, training, maintenance infrastructure and long-term sustainment. The transition from the Hornet and Tiger fleets to the F-35A also reflects the changing nature of air defence, where situational awareness, sensor fusion, data processing, electronic support measures and secure information exchange have become as important as traditional speed, altitude and manoeuvrability.

For the Swiss Air Force, the F-35A introduces a different operational architecture. Unlike legacy combat aircraft designed around separate onboard sensors and pilot-managed information flows, the F-35A is built as an integrated combat system, combining radar, electro-optical sensors, electronic support capabilities and secure data links into a fused tactical picture. In Swiss service, this could support faster threat evaluation, more efficient interception profiles and improved coordination with national air surveillance and command structures. Its low-observable design and digital mission systems also offer growth potential through future software increments, mission-data updates and interoperability with partner systems where authorised by Swiss policy and operational requirements. This wording is important for a neutral state, as Switzerland’s future fighter capability must remain fully compatible with sovereign decision-making and national rules of engagement.

The programme also includes an industrial and institutional dimension. Industrial cooperation linked to the F-35A acquisition involves Swiss companies in areas such as research, development, production and maintenance-related activities. One example is the cooperation involving Pilatus Aircraft on a pilot training system tailored to fifth-generation air forces. This approach connects procurement with domestic aerospace competence and ensures that the fighter replacement programme is not limited to aircraft delivery alone. At the same time, the remaining logistics deliveries associated with the F/A-18C/D life-extension programme, mainly replacement material and support services, are expected to be completed within the approved credit by the end of 2027. Switzerland is therefore managing two overlapping but complementary processes: keeping the Hornet fleet credible until the early 2030s while preparing the national ecosystem required for the F-35A.

Switzerland’s decision to extend the operational life of the F/A-18C/D Hornet while the first Swiss F-35A enters assembly reflects a coherent and pragmatic airpower transition. It preserves immediate air policing and air defence readiness, gives the Swiss Air Force time to absorb a fifth-generation aircraft with a broader digital, training and sustainment ecosystem, and supports continuity in combat aviation capacity throughout the transition. In diplomatic and operational terms, the message is clear: Switzerland is not merely replacing one fighter fleet with another, but managing a generational transformation of its air defence system. By keeping the Hornet fleet available into the early 2030s and preparing the arrival of 36 F-35A aircraft, Bern is securing a stable, sovereign and technically credible pathway for the future protection of Swiss airspace.
