Parliamentary watchdog condemns Swiss handling of F-35 fighter deal
A parliamentary oversight committee has accused the Swiss government and defence ministry of serious administrative failures in the procurement of 36 F-35 fighter jets. The committee says no fixed-price agreement was secured with the United States, despite categorical assurances to parliament and the public, raising questions about accountability and the programme’s eventual cost.
Switzerland’s parliamentary watchdog has found that the government never secured the fixed price used to justify the country’s F-35 purchase. The finding strikes at the centre of a procurement programme that has already forced Bern to seek hundreds of millions of francs in extra funding.
In a report published on September 8, 2026, the National Council’s parliamentary oversight body, known as the GPK-N, said no flat-rate fixed price had been agreed with the United States for the 36 F-35A fighter jets. The committee said this made the defence ministry’s categorical assurances to parliament and the public difficult to understand.
The ministry had repeatedly presented the aircraft deal as a CHF 6 billion purchase at a fixed price. A year ago, the government acknowledged that the arrangement could not be maintained and requested a supplementary credit of just under CHF 400 million, equivalent to about $495 million. It later said the higher costs meant Switzerland could buy only around 30 aircraft.
The report shifts the dispute from a question of rising prices to one of administrative responsibility. It identifies weaknesses in negotiation management, internal oversight and the flow of information, placing the F-35 programme under renewed scrutiny in Bern.
Report finds controls missing
The GPK-N says the defence ministry entered critical talks without a clear negotiating mandate. That omission left officials without a documented framework for protecting Switzerland’s position as the United States revised the financial terms.
The committee also criticised the size and structure of the negotiating group. According to the 95-page report, a very small number of people supervised the talks, while the ministry failed to manage the process closely enough. Information did not move adequately through the administration or to the political authorities responsible for oversight.
The report’s most pointed criticism concerns internal controls. “In certain phases, even the most basic form of oversight was lacking,” it said, referring specifically to a simple dual-control principle. In practice, that means key decisions and information were not consistently checked by a second responsible official or body.
The committee’s findings do not establish that the United States breached a signed flat-rate contract. They establish that Swiss authorities presented the arrangement with a level of certainty that the underlying agreement did not support. That distinction matters for public finance, because parliament approved the programme on the basis of the government’s assurances about cost and scope.
The GPK-N described the organisation of the negotiations as inappropriate, adding to pressure on the defence ministry to explain who knew what, and when.
