The Swiss government is seriously considering canceling its order for the Patriot air-defense system from the United States as severe delivery delays continue to strain bilateral defense ties, Defense Minister Martin Pfister announced on Wednesday. Switzerland originally contracted for five Patriot batteries in 2022 with deliveries scheduled to begin in 2026 and conclude by 2028, but the timeline was upended last July when Washington informed Bern that deliveries would be reprioritized to support Ukraine's urgent defense needs. "Cancellation is always an option in the event of a delay," Pfister told the ATS-Keystone news agency, though he acknowledged that the conditions for such a termination remain unclear.
Payment Freeze Extended
Switzerland first suspended payments for the Patriot system in the fall of 2025, intending to use the freeze as leverage to secure more reliable delivery timelines from the United States. However, the payment freeze has proven largely ineffective, as the US has circumvented it by redirecting Swiss funds intended for other defense programs. Urs Loher, director of armaments at the Swiss defense procurement agency armasuisse, confirmed that US authorities have diverted payments from Switzerland's F-35A fighter jet account to cover Patriot program costs, a move described as "very unsatisfactory" by Swiss officials.
The redirection is possible because all Swiss arms purchases under the Foreign Military Sales (FMS) program are paid into a single US-managed fund, allowing the Pentagon to reallocate money between programs as needed. The amount diverted is reportedly in the "low three-digit million" Swiss franc range, exceeding 100 million francs ($126 million). This maneuver has created budget gaps for Switzerland's F-35 program, forcing the Defense Ministry to advance additional funds ahead of schedule to maintain that procurement.
Cost Overruns and Extended Delays
The delivery outlook for Switzerland's Patriots has worsened considerably since the original timeline was established. Swiss officials now anticipate delays of at least four to five years, with some estimates suggesting the wait could stretch even longer due to surging global demand for Patriot systems following the outbreak of the US-Israeli conflict with Iran. In February, Washington also informed Switzerland that the system's cost could increase by as much as 50 percent, pushing the total purchase price from CHF 2 billion to an estimated CHF 3 billion ($3.8 billion).
European Alternatives
The Patriot procurement crisis has accelerated a broader shift in Swiss defense acquisition strategy toward European suppliers. In early March, the Swiss government announced plans to acquire a second long-range surface-to-air missile system, with a preference for European-made equipment. The Franco-Italian SAMP/T system, developed by Eurosam, has emerged as the leading candidate, having already secured a procurement order from Denmark and demonstrated operational deployment capability. This pivot reflects a strategic reassessment of Switzerland's traditional reliance on US defense supply chains, driven by concerns about delivery reliability, cost predictability, and the limitations placed on neutral nations by the US FMS framework.
Impact on Broader US-Swiss Defense Relations
The tensions over Patriot deliveries come amid parallel strains in other defense programs. Switzerland recently reduced its F-35A fighter jet order from 36 to 30 aircraft after the United States increased the program's price, citing inflation and rising raw material costs. Swiss officials have warned that the liquidity issues created by the Patriot payment diversion could affect the entire Swiss FMS portfolio with the United States, potentially jeopardizing spare parts for existing F/A-18 aircraft and future F-35 deliveries.
The Swiss Defense Ministry expects to submit a recommendation to the Federal Council on the Patriot procurement's future by the end of June 2026, after receiving updated delivery schedules and cost estimates from Washington. Swiss lawmakers across party lines have expressed frustration with the situation, with some questioning whether Switzerland should continue entering FMS agreements with the United States given the recurring challenges with contract interpretation and unilateral US actions.
