Built in England (Newcastle upon Tyne) in 1907, Tarmo was the Grand Duchy of Finland’s third icebreaker upon its completion. As foreign trade continued to grow at the beginning of the 20th century, the two previous icebreakers, Murtaja (1889) and Sampo (1898), were no longer sufficient to keep the sea routes open for traffic during winter. At first, the main purpose of the icebreakers was to keep the routes open to Finland’s winter ports in Hanko and Turku and to prolong the sailing seasons of the ports of Helsinki, Kotka, Mäntyluoto, Rauma and Vaasa. The icebreakers also aided ships in distress.

Tarmo represents an American type of icebreaker with a sharp bow. During the first decades of the 20th century, it was the most powerful and efficient icebreaker in Finland, able to advance through 80 cm thick solid ice. The bow propeller made it easier to advance in icy waters, and in more difficult conditions the vessel advanced by lunging at the ice. Tarmo’s speed was 13 knots in open water.

During the First World War, Tarmo served in the Baltic Fleet of the Imperial Russian Navy, assisting naval ships and troop transportations. When Finland became independent in 1917 and civil war broke out in January 1918, the vessel was still under Russian command in Helsinki. At the order of the Chairman of the Senate, P. E. Svinhufvud, Tarmo was captured by Finnish independence activists.

During the Winter War, the icebreakers were armed and assigned to the Finnish Defence Forces. In January 1940, Tarmo was bombarded at the port of Kotka, resulting in the deaths of 39 men and leaving 13 injured. The vessel’s bow was badly damaged in the incident, with some of the interiors destroyed by fire. During the Continuation War, Tarmo took part in Operation Nordwind, a distraction manoeuvre carried out south of the island of Utö.

Tarmo remained in use until 1970, having been renamed Apu some years prior. After this, the decision was made to restore the ship into a museum ship. The restoration was carried out at Kotka Shipyard between 1990 and 1992. The Finnish Maritime Administration handed the restored ship over to the Finnish Heritage Agency, and in 1992 Tarmo was placed in Kotka. Since July 2008, Tarmo has been open to the public in the museum ship pier of Maritime Centre Vellamo as part of the exhibitions of the Maritime Museum of Finland.
