How Switzerland built a modern air force while maintaining a policy of strict neutrality.

In short: Established just days before the outbreak of World War I, the Swiss Air Force evolved from a small collection of commandeered civilian planes into a sophisticated military branch. Despite Switzerland's neutral status, the force has navigated complex airspace violations, internal political scandals, and the unique challenges of mountain-based defense.

The Swiss Air Force was formally established on 31 July 1914, initially as an army component. During World War I, its activities were limited to reconnaissance and training. However, the international instability of the 1930s prompted a significant expansion, leading to the acquisition of Messerschmitt Bf 109 and Morane-Saulnier D-3800 fighters. By October 1936, the service became an autonomous military branch. Throughout World War II, Switzerland maintained neutrality but faced thousands of airspace violations. Swiss pilots intercepted both German and Allied aircraft, leading to several shootdowns and the internment of foreign aircrews.

Post-war doctrine shifted toward protecting Swiss sovereignty against potential nuclear threats and invasions. This led to the adoption of jet aircraft like the De Havilland Vampire and the construction of innovative infrastructure, including hangars carved into mountains and highways reinforced to serve as emergency runways. In 1964, a major procurement scandal involving Dassault Mirage 3 fighters forced the resignation of top military officials, triggering a complete restructuring of the air force in 1968. This period also saw the introduction of advanced radar systems like the FLORIDA network, which was later replaced by the current FLORAKO system in 2003.

Today, the Swiss Air Force operates as a hybrid of career military personnel and reservists, maintaining 24/7 air policing and radar coverage. While the force previously operated on limited hours—famously failing to respond to a 2014 hijacking that occurred outside of its 06:00-22:00 window—it has since modernized its readiness. The current fleet includes McDonnell Douglas F/A-18 Hornets and Northrop F-5 Tiger IIs. In 2021, the F-35A was selected as the winner of a massive procurement competition, marking the latest chapter in Switzerland's ongoing effort to balance its limited size with the need for effective national air defense.
