Patria Assembles Finland's First F135 Engine at Linnavuori Ahead of Rovaniemi F-35A Deliveries
Nokia, 3 September 2026
Key points
- Patria completed assembly of Finland's first F135 engine, the powerplant for the F-35A, at its Linnavuori facility in Nokia
- The work follows a 2024 frame contract for F135 maintenance, repair, overhaul and upgrade, and a February 2026 agreement adding final assembly
- Assembly runs at Linnavuori through 2030, creating roughly 50 direct jobs over that period
- Petri Hepola, Patria's chief programme officer for F-35: the completed engine is "a significant milestone and a strong start" for F135 assembly in Finland
- The first F-35As are due at the Lapland Air Wing, Rovaniemi, this autumn
Patria assembled Finland's first F135 engine at its Linnavuori plant on 3 September, converting a February final-assembly agreement into hardware weeks before the Lapland Air Wing's first F-35As arrive at Rovaniemi this autumn.
The engine work sits inside a maintenance relationship that predates it: Patria and Pratt and Whitney signed a frame contract for F135 maintenance, repair, overhaul and upgrade in 2024, before Finland had taken delivery of a single jet. February 2026's agreement extended that into final assembly, and Linnavuori is now running production through 2030, with around 50 direct jobs attached. Hepola's "strong start" framing is the operative claim: assembly, not just sustainment, is the stated end state at the Nokia site.
The timing lines up with the aircraft. Finland is due its first F-35As at the Lapland Air Wing in Rovaniemi this autumn, and Großwald's earlier record of Finland's GBU-53/B StormBreaker buy for the same fleet tracked the munitions side of that build-up; engine assembly is the sustainment side arriving on the same clock. Neither the 50 jobs nor the 2030 horizon is large by European fighter-programme standards, and domestic engine assembly is an arrangement the Dutch and Norwegian F135 depots approach from the maintenance side rather than from the production line.
An assembly line is a supply-chain fact, not an operational one. Finland's F-35A fleet stays dependent on Pratt and Whitney's global logistics network and technical authority regardless of where the engines are bolted together; Linnavuori adds throughput and about 50 jobs and changes nothing about design authority or export licensing. Großwald's Signal No. 138 carried the engine as a procurement card; the fact that outlasts the card is that Finland's F-35 sustainment runs from a domestic site before the first aircraft has landed.
