The Federal Audit Office reports that the infrastructure conversion for Switzerland's new F-35 fighter jet fleet is significantly over budget and behind schedule. Projects at key airfields like Payerne and Meiringen face delays of up to a year, casting doubt on the planned mid-2027 arrival of the aircraft.

"I am confident that if the construction continues as planned, we will be able to hand everything over on time."
"Today, there are enough hangar spaces available in Switzerland for the future F-35s."
A staggering CHF 200 million is the new price tag for Switzerland's F-35 infrastructure, shattering the original budget and sending shockwaves through the Federal Palace. The Federal Audit Office has issued a blistering report revealing that the financial planning for the country's premier defense acquisition is in disarray. What was once a parliamentary approved loan of CHF 120 million in 2022 has now ballooned by nearly 70%, with no guarantee the ceiling has been reached.
The root of this fiscal fiasco lies in a premature calculation made three years before the F-35 was even selected as Switzerland's fighter of choice. The budget was set in stone without a clear understanding of the specific, high-tech requirements needed to house and maintain the American-made stealth jets. Now, reality has bitten hard. The funds set aside for the Payerne project have already been completely exhausted, forcing the army to scramble for a supplementary loan this year just to cover the bare necessities. This is not just an accounting error; it is a fundamental failure in procurement planning that leaves taxpayers footing a significantly larger bill than promised.
Time is rapidly running out for the Swiss Air Force. With the first F-35 jets scheduled to touch down from the United States in mid-2027, the ground beneath them is far from ready. The audit report exposes alarming delays across key military sites, casting serious doubt on the operational timeline. Construction at the pivotal Payerne airfield only commenced in spring 2025—a critical six months behind schedule.
The situation is even more dire at Meiringen and Emmen, where essential infrastructure projects are lagging by at least a year. These are not merely cosmetic upgrades; these facilities require specialized hangars, simulator rooms for pilot training, and secure mission planning centers. The auditors explicitly criticized project leaders for severely underestimating the time required to retrofit aging Swiss airfields for 21st-century warfare. As the clock ticks down to 2027, the gap between the arrival of the jets and the readiness of the bases is widening, threatening to leave the world's most advanced fighter planes without a proper home upon delivery.
Beyond the headline budget blowout, a shadow ledger of costs has emerged, drawing sharp rebuke from federal auditors. The report uncovers an additional CHF 50 million in required spending that falls outside the primary renovation budget. These funds are earmarked for "less essential" projects and maintenance on existing buildings that will eventually service the F-35 fleet. By categorizing these as separate from the main procurement costs, the true financial impact of the F-35 integration remains partially obscured.
The auditors have slammed this lack of transparency, arguing that the total cost of ownership is being fragmented. Armasuisse, the federal office for defence procurement, has admitted that the current CHF 200 million estimate covers only the absolute essentials required to commence flight operations. Any infrastructure deemed not immediately critical has been pushed to a later date, creating a looming financial burden for the future. This "pay-as-you-go" approach to national defense infrastructure raises uncomfortable questions about what other costs might be lurking in the long grass as the project evolves.
Despite the scathing audit and mounting delays, defense officials are projecting an air of unshakeable confidence. Marcel Adam, head of the real estate competence unit at Armasuisse, insists that the situation is under control. "I am confident that if the construction continues as planned, we will be able to hand everything over on time," Adam told public broadcaster SRF, attempting to quell fears of a logistical bottleneck.
Adam argues that the coordination between construction and jet commissioning remains intact, stating boldly, "Today, there are enough hangar spaces available in Switzerland for the future F-35s." He maintains that the new CHF 200 million estimate will suffice for the "bare necessities" needed to get the jets in the air. However, with Armasuisse pledging to overhaul its estimation processes for future projects, there is a tacit admission that the previous methods were woefully inadequate. As the 2027 deadline looms, the Swiss public is left to watch a high-stakes race between bureaucratic optimism and the cold, hard reality of construction schedules.
