Vesikko’s History and Significance

Construction and Early Service

Vesikko was constructed in 1933 at the Crichton-Vulcan shipyard in Turku as a secret prototype for Germany’s rearmament, which was prohibited from building submarines by the Treaty of Versailles. Disguised as a civilian research project by the Dutch company Ingenieurskantoor voor Scheepsbouw, the submarine was designated CV 707 during its trials. In 1934, Finland acquired the vessel, naming it after the European mink—‘vesikko’ in Finnish (Uboat.net).

World War II Operations

During the Winter War (1939–1940) and the Continuation War (1941–1944) against the Soviet Union, Vesikko served a vital role in Finland’s naval defense, conducting patrols and escort missions. Its most notable wartime achievement was the sinking of the Soviet merchant ship Vyborg in 1941—one of the few submarine victories in the Baltic Sea during WWII (Lonely Planet).

Decommissioning and Museum Conversion

Due to the 1947 Paris Peace Treaty, Finland was prohibited from operating submarines, leading to the decommissioning of Vesikko and her sister vessels. While the rest of the fleet was scrapped, Vesikko was saved thanks to the efforts of Finnish naval veterans and preservationists. In 1973, Vesikko reopened as a museum ship in Suomenlinna, enabling the public to experience a unique piece of Finnish and European naval history (Suomenlinna Official Site).

Cultural and Educational Value

Vesikko is not only a feat of naval engineering but also a symbol of Finnish endurance and ingenuity during turbulent times. Its preservation reflects Finland’s commitment to remembering its complex wartime history. As the only surviving Finnish WWII-era submarine, Vesikko offers an unparalleled educational experience—inviting visitors to explore the realities of submarine warfare through original equipment, detailed exhibits, and interactive interpretation. The submarine’s presence within Suomenlinna enhances the narrative of the fortress, which spans three centuries of defense and adaptation (Lonely Planet).
