Defence Tech Companies in Finland
Finland's defence budget hit a record $7.3 billion in 2025, up 12 per cent year on year, driven partly by F-35 acquisition costs and the country's NATO commitments following its accession in 2023. Patria, the state-backed prime contractor, dominates the industrial base and in mid-2025 opened a joint facility with Lockheed Martin to assemble 400 F-35 fuselages, while its 2024 acquisition of Nordic Drones signals a push into the unmanned systems market. Finnish defence startups captured 85 per cent of all Nordic dual-use funding in 2025, totalling $410 million.
