Switzerland confirms independent operation of F-35A fighters and Patriot air defence system

Concerns were raised in a recent CH-Media report regarding dependencies on American technology for Swiss defence operations. In response, the DDPS stated that the F-35A’s electronic systems cannot be remotely controlled or blocked by external actors, ensuring Switzerland’s full operational sovereignty.

The Swiss Air Force will receive the latest Block-4 version of the F-35A, identical to those supplied to the US and other partner nations. The contract with the US guarantees the same standards, ensuring Switzerland’s fleet maintains equal capabilities to other allied forces.

Regarding missile system upgrades, Switzerland clarified that it has never sent an AMRAAM missile to the US for a software update. Any updates to guided missile systems remain optional, and if selected, they would be conducted in Switzerland with US technical support.

Switzerland also addressed concerns about reliance on US-based data communications and navigation technology, such as Link-16 and GPS. While these systems are standard across all Western aircraft, including European models, the F-35A and Patriot system remain fully operational even without satellite navigation or data links.

The Patriot missile defence system, which Switzerland is also acquiring, does not require specialised US radar data for intercepting ballistic or hypersonic missiles. The system operates independently with its own radar capabilities, reinforcing Swiss defence autonomy.

Swiss authorities acknowledged that complete independence from foreign military technology is impractical, as no country produces all its defence systems domestically. However, Switzerland aims to maximise its operational and technical self-sufficiency while benefiting from international cooperation.

The F-35A’s advanced sensor suite provides pilots with a real-time situational picture, enabling autonomous data processing for combat operations. With multiple European nations, including Italy and Germany, also acquiring the F-35A, Switzerland stands to gain additional interoperability advantages and security cooperation opportunities.

While the US enforces strict export controls to prevent unauthorised weapons transfers, Switzerland has no intention of re-exporting its F-35A fleet. The acquisition is solely for national defence, ensuring no restrictions on Swiss use of the aircraft.

As the F-35A becomes one of Europe’s most widely used fighter jets, Switzerland’s procurement aligns with broader regional defence trends. The country remains committed to maintaining the highest level of autonomy while benefiting from advanced technology and international security partnerships.
