Summary

On December 14, 2023, Finland announced its plan to invest more than $130 million over the next three to four years to double the production of artillery and mortar ammunition. This initiative, aligned with European efforts to support Ukraine, focuses on heavy ammunition, including 155mm artillery shells and 31mm and 120mm mortar rounds. The investment will enhance the manufacturing capacity of charges, propellants, and explosive filling, with completion expected between 2026 and 2027. Production expansion is expected primarily on sites operated by the Norwegian-Finnish Nammo group, a major ammunition producer in Europe. The Finnish Defense Forces remain responsible for explosive filling, while Nammo Lapua Oy and Nammo Vihavouri Oy produce components and raw materials. The ramp-up supports Helsinki's commitment to increase military aid to Ukraine amid the ongoing conflict with Russia and European Union's slow progress in ammunition supply.
