Finland has completed its new F135 engine assembly and maintenance center in Linnavuori, marking a key milestone ahead of its F-35A deliveries in 2026. The facility deepens Finland’s role in NATO’s air defense network and strengthens logistics support for fifth-generation aircraft in the Arctic region.
On October 14, 2025, Finland officially completed the new F-35 engine assembly and maintenance facility in Linnavuori, Nokia, delivered on schedule to Patria. The site marks a major step in Finland’s integration into the global F-35 support network as the country prepares to receive its first F-35A fighters at Rovaniemi Air Base by late 2026. Built under the direction of Defence Properties Finland, the facility meets the high safety and security standards required by Pratt & Whitney and the U.S. F-35 program, as reported by Patria.

At the core of this new capability lies the Pratt & Whitney F135 engine, which powers all F-35 variants and is considered one of the most sophisticated jet engines ever produced. The Linnavuori plant will first focus on assembling F135 engines and components between 2025 and 2030, before transitioning to full-scale maintenance, repair, and overhaul operations from 2030 onward. This long-term program positions Patria as a key strategic partner in the regional sustainment of the F-35 fleet, ensuring Finland can maintain its aircraft independently throughout their operational lifespan.
The project traces back to Finland’s HX Fighter Program, finalized in 2021, valued at approximately €9.4 billion, covering aircraft procurement, infrastructure, and support. Patria’s agreement with Pratt & Whitney, signed in 2024, guarantees local assembly capacity while embedding Finland into the multinational logistics chain that underpins the F-35’s operational readiness. The facility’s construction progressed under tight U.S. oversight and passed all required security inspections before handover, demonstrating the maturity of Finland’s defense-industrial ecosystem.
Operationally, the new facility gives Finland a self-sustaining engine maintenance capability, reducing turnaround times and dependency on external hubs. It complements existing European F135 centers in Woensdrecht (Netherlands) and Rygge (Norway), but adds critical redundancy in Northern Europe, particularly valuable for Arctic and Baltic operations. Much like the early development of European F135 depots, Linnavuori follows a phased approach to reach full operational readiness, incorporating lessons learned from allied partners while maintaining a faster implementation timeline.
Strategically, this milestone extends NATO’s technical depth along its northern flank. With Finland’s accession to the Alliance, Linnavuori now acts as a northern anchor for engine sustainment, supporting rapid response and long-range deterrence capabilities in the High North. The facility enhances resilience in case of regional disruptions, while boosting interoperability with other F-35 operators in the Nordic and Baltic regions. Militarily, it solidifies Finland’s role as both an operational and industrial contributor to the Alliance’s collective airpower posture.
Financially, the F-35 program’s broader engine production framework continues to expand. In August 2025, Pratt & Whitney received a $2.8 billion contract modification for the Lot 18 F135 engines, confirming steady demand across partner nations. The 2024 agreement with Patria remains Finland’s latest direct industrial offset within the program, generating an estimated 50 skilled jobs during the assembly phase. Though the specific construction budget has not been disclosed, the project forms part of Finland’s national defense infrastructure investments tied to the HX program.
The completion of the Linnavuori F135 engine facility signals more than industrial readiness; it marks Finland’s emergence as a trusted node in NATO’s most advanced defense network. As the first F-35s prepare to arrive, Finland now holds the capacity to assemble, service, and sustain the heart of its next-generation air fleet, securing both national sovereignty and long-term alliance resilience in Europe’s increasingly contested northern skies.
