With deliveries of American Patriot air defense systems having become highly uncertain, Switzerland has decided to canvas the market. Requests for information have been sent to five manufacturers from France, Germany, Israel, and South Korea.
The key criteria for selecting an air defense system have been identified as delivery timelines, cost, effectiveness, and the share of production located in Europe, ideally in Switzerland itself. The information-gathering process will run until the end of May, Switzerland's Federal Office for Defence Procurement (Armasuisse) announced, as reported by SWI.

For now, this remains an information-gathering exercise a preliminary step ahead of either a formal tender or a sole-source procurement justification. The very fact of this activity signals, however, that Switzerland will not default unconditionally to the franco-Italian SAMP/T NG, which Eurosam has promised to deliver by 2029.
The list of manufacturers from the four countries has not been officially disclosed, but Defense Express can offer some informed assessments particularly given that Switzerland is seeking a long-range air defense system with ballistic missile defense capability. The French manufacturer in question may be Eurosam, which is headquartered in Paris.
The only South Korean system with anti-ballistic capabilities is the KM-SAM II, whose missiles are produced by LIG Nex1, with the system's vehicles, including the radar, manufactured by Hanwha Aerospace. The KM-SAM II has already recorded its first confirmed ballistic missile intercept in real combat conditions, achieved in the UAE during the repelling of one of iran's attacks.
The German proposal almost certainly points to Diehl Defence, the country’s sole air defense system manufacturer. However, ballistic missile intercept capability has not yet been declared for its new IRIS-T SLX, which has an 80 km range and remains in development, currently on track for completion only by the end of this decade. That said, this option would make logical sense for Switzerland from a standardization standpoint: in 2025, the Swiss government procured five IRIS-T SLM systems for €700 million in a medium-range air defense competition that had only a single participant.
As for potential Israeli contenders, two systems in the Patriot class are plausible: David's Sling by Rafael, which has a proven ballistic missile intercept capability, and the Barak MX by Israel Aerospace Industries, for which such capability has been declared.
As a reminder, in 2021 Switzerland ordered five Patriot batteries for CHF 1.987 billion (approximately $2 billion at the time of signing, equivalent to around $2.6 billion today), with deliveries scheduled between 2026 and 2029. The U.S. government subsequently delayed deliveries for an unspecified period, citing priority given first to Ukraine and now to the war against iran. In response, Switzerland suspended payments under the contract, though it has already transferred CHF 650 million, or roughly one-third of the total, as an advance. Unwinding that agreement with the United States may prove far from straightforward.
