Vesikko

About the museum

Vesikko was built at the Crichton-Vulcan shipyard in Turku, and its keel was laid in August 1931. The vessel was launched on 10 May 1933 and tested in the Turku archipelago. The Finnish state took the boat into use in 1934 and bought it in 1936, when it became the Vesikko.

From autumn 1939 the vessel carried out neutrality patrols. In the Continuation War, on 3 July 1941, Vesikko sank the Soviet cargo ship Vyborg east of Suursaari. It was the first enemy vessel sunk by a Finnish submarine using a torpedo. The boat was taken out of service in 1944. The Paris Peace Treaty of 1947 prohibited Finland from owning submarines, and Vesikko was the only Finnish submarine to be spared scrapping.

The Sotamuseo opened the vessel as a museum on 9 July 1973. The boat was thoroughly restored in 2011–2013, when the rusted keel and deck timbers were replaced, the hull was painted and the vessel was raised by 80 centimetres. Vesikko lies on the shore of Tykistölahti at Susisaari in Suomenlinna. Visitors see the cramped working conditions among the engines and torpedoes.
