The Pohjanmaa class is a series of four multi-role corvettes currently under development for the Finnish Navy as part of the Squadron 2020 (Finnish: Laivue 2020) project. Together with the existing four Hamina-class missile boats, the four new surface combatants will form the backbone of the Finnish Navy from the mid-2020s onwards. They will replace seven older vessels that have been or are due to be decommissioned; the minelayer Pohjanmaa, two Hämeenmaa-class minelayers and four Rauma-class missile boats.
