Bern has confirmed that the F-5 Tiger will be phased out by 2027, with major implications for the Patrouille Suisse. Budgetary issues, aviation heritage, and the transition to the F-35A.
Summary
Switzerland will decommission the F-5 Tigers by the end of 2027 at the latest, a decision that has now been finalized in Parliament. The withdrawal ends more than half a century of operational use and directly affects the Patrouille Suisse, the Swiss Air Force’s aerobatic team. The F-5s were chosen in the 1970s for their moderate cost, simplicity, and suitability for the country’s air defense. The current debate pits the heritage and educational value of the demonstration team against rising operating costs and capability priorities. At the same time, the Air2030 modernization program is moving forward: 36 F-35As are scheduled to enter service from 2028, with a tight multi-year budget. The executive branch has ruled out the idea of keeping the F-5s in service for longer, but has opened the door to transferring some aircraft to museums or foreign partners, or reselling the airframes. The future of the Patrouille Suisse brand and the format of air shows after 2027 remain to be decided.
The timetable and the political decision
The decision to withdraw the F-5s by the end of 2027 at the latest is part of an already mapped out political trajectory. Parliament has confirmed the withdrawal of the fleet while framing the transition to the 36 F-35As of the Air2030 program. Several steps explain this timetable: gradual reduction of the F-5 fleet over the past decade, transfers abroad, and maintenance of a core fleet for secondary missions (target towing, training). The General Staff has acknowledged that the marginal cost of extending the fleet (parts, structural inspections, corrosion monitoring, J85 engines) is no longer justified in view of the capacity gains expected with the arrival of the F-35As. The 2025-2028 window is the focus of the trade-offs: integration of the F-35A squadrons, adaptation of infrastructure (hangars, security, tools), and phased withdrawal of the F-5s to avoid a “capability gap.” The Patrouille Suisse is thus protected until 2027, but with no guarantee beyond that.
The historic choice of the F-5 and its role in Switzerland
The F-5 emerged in the late 1960s as a light twin-engine fighter, robust, inexpensive, and suitable for restricted terrain. Its moderate weight, simple maintenance, and low cost per flight hour were in line with Switzerland’s approach to distributed air defense, with aircraft dispersed across several bases. Over the decades, the F-5s have relieved the F/A-18s in utility roles: target presentation, training, and limited air policing during the day and in good weather. In this context, the Patrouille Suisse performed a representative and technical educational role, demonstrating the basics of close formation flying and precision piloting. However, changes in traffic, safety requirements, and the costs of maintaining older aircraft have gradually reduced the military interest in extending its service life. The F-5 remains a symbol; it is no longer a relevant tool for modern combat training.
Costs, availability, and budgetary trade-offs
Switzerland has to cope with tight annual budgets. The withdrawal of the F-5 saves maintenance slots, spare parts stocks, and mechanic hours, which can be reallocated to the F-35A and associated ground systems. The cost factors are clear: original parts are becoming scarce, structural repairs are more frequent, engines are unreliable, and compliance with current standards is an issue. Even though the F-5 has a low direct cost, fleet logic dictates that efforts should be focused on modernizing air defense. In terms of presentations, adding a typical air show requires fuel, logistics, and the mobilization of ground crews. In a context of energy and financial restraint, the General Staff favors operational presence. The political framework for the F-35A acquisition (approved budget, regular audits) reinforces this hierarchy: every franc spent on an aging airframe is one less franc for the ramp-up of the F-35 system (simulators, tools, cryptos, data links).
The consequences for the Patrouille Suisse
The sensitive issue is public: what will become of the Patrouille Suisse after 2027? Several options are being explored. The first option is to simply shut it down, at the risk of losing heritage and visibility among the general public. The second option is to continue the brand with a turboprop trainer, such as the Pilatus PC-7 or PC-21. Advantages: reduced costs, simple logistics, less noise at the sites. Limitations: less symbolic and attractive than a jet. The third option is a reduced core of domestic presentations, with a very limited policy of overseas appearances. The ministry has already restricted demonstrations outside Switzerland to exceptional cases, for budgetary and environmental reasons. Whatever the choice, the team will have to adapt its programs (altitudes, distances, procedures) to the scale of the selected platforms, while maintaining flight safety as a non-negotiable constraint.
The future of Swiss F-5s after retirement
Some of the airframes have already been exported to serve as “aggressors” within allied forces. This outlet extends the life of the aircraft in a useful role: a realistic adversary for air combat, with limited costs. Other airframes could be added to Swiss museums or private collections, after military neutralization and compliance. The rest will be cannibalized for parts or dismantled. This diversity of end-of-life options is rational: it reduces fleet exit costs and maximizes residual value. Operationally, the retirement of the F-5s clarifies the fleet architecture: F-35As for front-line operations, PC-21s for advanced training, and helicopters for search and rescue and support. The country thus retains a coherent system that is better suited to today’s threats and constraints.
The transition to the F-35A and the “mission-exhibition” balance
Starting in 2028, the gradual arrival of the F-35A will reshape training, maintenance, and the use of air assets. The priorities are availability, airspace protection, and European interoperability. In this context, the “mission-exhibition” question arises without emotion: an aerobatic team serves communication and national cohesion, but must not burden operational readiness. The most likely solution combines maintaining an air heritage with a less expensive turboprop aircraft and refocusing fighter jets on their core business. Switzerland is not abandoning its aeronautical culture; it is adjusting it. The challenge now is to explain this choice to the public, quantify the expected benefits, and preserve what matters: trained crews, a balanced budget, and a credible posture in the face of contemporary risks.
