The Swiss federal government announced on Wednesday that it will withhold further payments to the United States for its ordered Patriot missile defence system until it receives binding delivery dates. Authorities say both the delivery schedule and the associated payment milestones are currently uncertain.
Officials emphasised that pausing payments is intended to secure clearer contractual commitments from the U.S. side. The government also said that termination of the Patriot purchase remains an option while negotiations continue.
Defence Minister Martin Pfister told reporters at a news conference that, despite the payment pause, the government still expects to obtain the Patriot system. At the same time, he stressed that no course of action has been excluded.
"We are currently negotiating all possible options with the United States, and that includes a potential termination," Pfister said, adding that it was not clear what the conditions for any cancellation would be.
The government provided additional detail on how it is managing related procurement timelines. A payment connected to Switzerland's order of F-35A fighter jets has been moved forward to the end of March 2026. Officials said this adjustment was made to ensure that acquisition of the aircraft is not jeopardised by decisions surrounding the Patriot system.
Looking ahead, the Defence Ministry indicated it will brief Switzerland's governing Federal Council on the recommended next steps for the Patriot procurement by the end of June. Until binding delivery dates and explicit payment milestones are established, the government will continue to withhold further payments tied to the missile system order.
The current stance reflects a negotiated approach that keeps multiple outcomes possible - continued procurement under clarified terms, or a potential termination should acceptable conditions not be confirmed. The Defence Ministry's update to the Federal Council in June will determine how the purchase process proceeds.
