Located in Linnavuori, Nokia, the facility is a crucial part of Finland’s industrial cooperation in the F-35 fighter jet programme. The site, set to be completed in autumn 2025, is designed to enhance the security of supply for Finland’s future F-35 fleet.
Patria, the strategic partner of the Finnish Defence Forces, will operate the new facility. Initially serving as an assembly centre for F135 jet engines, the facility will later transition to maintenance operations, ensuring long-term support for Finland’s fleet.
Maintenance work will continue in Nokia throughout the lifespan of the Finnish F-35 jets. The Defence Properties Finland (Puolustuskiinteistöt), responsible for managing Finnish Defence Administration properties, oversees the construction of the facility.
Finland’s Minister of Defence, Antti Häkkänen, emphasised the significance of the new maintenance capabilities. He stated that having a domestic maintenance and support system for F135 engines strengthens Finland’s military security of supply and ensures operational readiness in all conditions.
No similar facilities currently exist in Finland, making this project a landmark development in the country’s defence infrastructure. The facility is being built to meet the strict safety and operational requirements set by the F-35 programme and American engine manufacturer Pratt & Whitney.
Defence Properties Finland’s CEO, Matias Warsta, confirmed that the construction has undergone extensive evaluations and met all required American inspections. He noted that collaboration with multiple stakeholders has been key to the project’s successful progress.
Patria’s Chief Program Officer for the F-35, Petri Hepola, expressed pride in the teamwork behind the construction. He highlighted the smooth cooperation between all parties and reaffirmed Patria’s commitment to developing Finland’s F-35 capabilities.
Patria signed an agreement with Pratt & Whitney in 2024 for F135 engine assembly and component production between 2025 and 2030. From 2030 onwards, the facility will transition to Maintenance, Repair, Overhaul, and Upgrade (MRO&U) operations, ensuring long-term sustainability for Finland’s F-35 programme.
