Finland signed a €546.8 million deal with South Korea to acquire 112 additional K9 Thunder 155 mm self-propelled howitzers. The purchase nearly doubles its fleet and strengthens NATO’s long-range artillery power on Russia’s border.

The 9 April 2026 government-to-government agreement with the Korea Trade-Investment Promotion Agency adds systems, spares, and support equipment, bringing Finland’s planned inventory to 208 guns. The deal accelerates Helsinki’s shift from towed artillery toward protected, mobile 155 mm fires, improving survivability and rapid-response strike capability across NATO’s northeastern flank

Finland is expanding its K9 Thunder fleet with 112 additional 155 mm self-propelled howitzers from South Korea, nearly doubling its inventory to 208 systems and significantly strengthening its mobile long-range artillery capability in response to the growing Russian threat and Europe’s broader rearmament drive (Picture source: Finland MoD).

The Finnish Ministry of Defence framed the deal as part of the Army’s long-term modernization and as a partial replacement for aging towed artillery. That matters strategically because Finland is no longer treating tracked 155 mm artillery as a limited specialist capability or a niche support arm for selected units. It is making armored, mobile, high-volume fires a central component of national land combat power at a time when Russian military pressure, force regeneration, and the lessons of the war in Ukraine have restored artillery to the center of European deterrence planning.

The scale of the order explains why Helsinki chose 112 rather than a smaller follow-on batch. Finland already has a mature K9 ecosystem, including trained crews, maintenance networks, support arrangements, and practical experience operating the system in demanding northern conditions. That means the newly acquired guns can be absorbed into the force structure without major new infrastructure or a prolonged transition. In force-planning terms, this is not a symbolic buy; it is a decision to enlarge the number of heavy tracked artillery units in a meaningful fashion and to push more of Finland’s firepower toward a survivable, modern format designed to remain relevant into the 2050s.
