The Hämeenmaa-class minelayers (Finnish: Hämeenmaa-luokan miinalaiva) is a two vessel strong class of coastal minelayers, used by the Finnish Navy. The ships have a steel hull and aluminum alloy superstructure. The class has an ice operating classification of ICE-1A and can operate year-round in ice up to 40 cm thick. The design included some first attempts on stealth technology in the Finnish Navy. During a crisis the main task for the Hämeenmaa-class ships is minelaying, but the vessels can also act as escort, transport and depot ships.
