Switzerland F-35 fighter jet program cost overruns

Reference TimelineLast updated APR 3
SUMMARY

Switzerland has reduced its order of F-35A fighter jets due to significant cost overruns, with the government announcing on March 6, 2026, that it could no longer guarantee the initial order of 36 jets within the voter-approved budget due to a CHF1.3 billion cost overrun. As of April 2, 2026, the US has redirected funds intended for Switzerland's F-35 program to cover Patriot air defense system costs, creating further budget shortfalls and potentially increasing the final F-35 bill by CHF 650 million to CHF 1.3 billion. The Swiss government will request an additional 394 million Swiss francs from parliament to offset rising costs, while F-35 infrastructure upgrades at Payerne, Meiringen, and Emmen airfields are delayed and facing budget overruns, with costs increasing from an initial CHF120 million to approximately CHF200-250 million. A 39% US tariff on Swiss exports has also contributed to the program's cost increases, and the F-35 jets are scheduled to begin arriving from the United States in mid-2027.
