F-35 price controversy exposes failures in Swiss defence procurement

The Swiss government’s promise of a CHF 6 billion fixed price has become the central casualty of the F-35 affair. On September 8, 2026, the House of Representatives Committee on the Examination of Public Accounts, known by its German acronym GPK-N, issued a sharp assessment of how Bern handled negotiations with Washington over 36 F-35A fighter jets.

The committee found that no flat rate fixed price had actually been agreed with the United States. That finding directly challenges repeated assurances from the Defence Ministry to Parliament and the Swiss public. The ministry had maintained that the aircraft would arrive under a fixed price arrangement, a claim that shaped the political case for replacing Switzerland’s ageing fighter fleet.

The dispute became public a year earlier, when the government acknowledged that the original price could not be maintained. Bern sought a supplementary credit of just under CHF 400 million for additional costs attributed to the US. It later said the higher bill could reduce the purchase from 36 aircraft to around 30.

For Swiss taxpayers, the controversy combines a major defence decision with a breakdown in confidence over how the numbers were presented. The committee’s report now shifts scrutiny from the aircraft itself to the officials and procedures that governed the deal.

A 95 page parliamentary report identifies failures at the negotiating table, not just a dispute over a final invoice. The GPK-N said the Defence Ministry did not establish a negotiating mandate before talks with the United States. That left officials without a clearly documented framework for what they could accept, reject or escalate.

The committee also criticised the size and organisation of the negotiating team. A small group oversaw the talks, while information did not move adequately through the ministry and government. The report said the ministry failed to manage the negotiations closely enough, limiting the ability of senior officials and oversight bodies to test the assumptions behind the price assurances.

The committee highlighted the absence of a basic dual control system during some phases. In practical terms, key decisions and information were not consistently checked by a second responsible official or team. Such controls are routine safeguards in complex public procurement, especially when a project involves foreign suppliers, long production timelines and billions of francs.

The findings place responsibility across an administrative chain rather than on one isolated exchange. They also explain why the committee objected to the ministry’s categorical public statements. Officials spoke with certainty while the underlying agreement did not provide the certainty they claimed.

The planned fleet could fall from 36 aircraft to around 30 because of the additional cost claim. Switzerland selected the F-35A as part of its Air2030 programme, presenting the purchase as a long term investment in the country’s air defence. The original public figure was CHF 6 billion for the 36 aircraft ordered from the United States.

The government later requested just under CHF 400 million in extra funding. The source report describes these costs as claims made by the US, while the parliamentary investigation focuses on Switzerland’s failure to secure and verify the price conditions it had publicly described as fixed. The dispute therefore affects both the budget and the planned military capability.

A reduction to around 30 jets would leave Switzerland with fewer aircraft than Parliament and the public were led to expect when the procurement was approved. The source does not provide a final per aircraft price or a detailed breakdown of the supplementary credit, so the full financial effect remains tied to the government’s handling of the negotiations and the eventual settlement.

That uncertainty has a direct political cost. Defence spending competes with transport, healthcare, social insurance and other federal priorities. Any request for additional funds must now be considered alongside a report that questions the ministry’s preparation, information flow and supervision.
