Patria is a strategic partner of the Finnish Defence Forces. The company [will assemble](https://www.patriagroup.com/newsroom/news/2026/patria-completes-the-assembly-of-finlands-first-f135-engine) the F135 engines that power Finland's F-35 fighters, and later maintain, repair and overhaul them.

Patria and Pratt & Whitney, an RTX business, agreed in February 2026 to begin final assembly of F135 engines in Finland. Production at Linnavuori is planned to run until 2030. The site will then shift to maintenance and sustainment work for the lifetime of Finland's F-35 fleet.

"The completion of the first F135 engine is a significant milestone and a strong start for F135 engine assembly in Finland," said Petri Hepola, Chief Program Officer, F-35 at Patria. He said the programme has now entered full-scale production.

Colonel (ret.) Henrik Elo, F-35 Program Director of the Finnish Air Force, said that this success "reflects the confidence placed in the capabilities of Finnish industry" and is a "clear demonstration of the close cooperation between the Finnish and US defence administrations and industries".

Finland's first F-35A fighters are due at the Lapland Air Wing in Rovaniemi this autumn.
