Finland has completed its first domestically assembled fighter jet engine, weeks before its own F-35s are due to arrive on home soil. Patria announced the milestone on September 3 at its new Linnavuori facility in Nokia.<\/p>\n
The achievement marks the country’s shift from simply buying F-35s to building the industrial capacity needed to keep them flying for decades. Senior representatives of Patria, Finnish defense authorities, and Pratt & Whitney attended the official ceremony marking the occasion.<\/p>\n
The completed F135 engine<\/a>, developed by Pratt & Whitney, powers all three F-35 variants and generates more than 40,000 lb of thrust. Patria and Pratt & Whitney, an RTX business, agreed in February to assemble the first F135 engines in Finland, with production planned to continue at Linnavuori through 2030.<\/p>\n A shift to upkeep<\/p>\n After 2030, the facility is set to shift toward maintenance, repair, overhaul, and upgrade work. That support would cover Finland’s F135 engines throughout the F-35 fleet’s operational lifetime.<\/p>\n That transition matters strategically. Finland is using its fighter purchase to build specialized propulsion expertise inside its own defense industry, rather than relying entirely on support performed abroad.<\/p>\n Patria’s 2024 framework agreement<\/a> with Pratt & Whitney for F135 maintenance work already extends Linnavuori’s role well beyond the current assembly phase. The assembly agreement itself is expected to directly employ around 50 people at Patria between 2025 and 2030. Building that expertise domestically, rather than importing it, is central to how Finland is approaching the F-35 program overall.<\/p>\n A larger sustainment network<\/p>\n Pratt & Whitney says more than 1,300 F135 engines currently support the global F-35 fleet. The company already operates maintenance, repair, overhaul, and upgrade capacity in the United States, Norway, the Netherlands, Japan, and Australia. Pratt & Whitney has said distributed sustainment matters increasingly in contested environments.<\/p>\n
