Vesikko
From Wikipedia, the free encyclopedia
Vesikko was a submarine of the Finnish Navy in World War II. It was designed by Dutch Ingenieurskantoor voor Scheepsbouw den Haag (I.v.S) and built in 1933 by the Chrichton-Vulcan shipyard in Turku, Finland. It served as a direct prototype (named as CV-707) for German Class IIA submarines. During the sailing-seasons 1933 and 1934 the German Navy carried out trials in the Achipelago of Turku. In 1936, the Finnish Navy bought it and named it as Vesikko.
Vesikko was one of five submarines to serve the Finnish navy. The other four were the three "Vetehinen class" boats Vetehinen, Vesihiisi and Iku-Turso (named after Finnish mythology characters, see Kalevala) and the small Saukko (Finnish for otter). The word "vesikko" means European mink, a small predator now near extinction.
During World War II Vesikko patrolled the Gulf of Finland and in 1941 managed to torpedo one Soviet merchant vessel called Vyborg.
After the war it was decommissioned because of the obligations of the Paris Peace Treaties that forbade submarines. The treaty obligations ended when the Soviet Union collapsed. Vesikko was lying as a wreck for years. It was eventually put up for sale for anyone willing to buy it. Fortunately submarine veterans managed to rescue it and restored it. The submarine currently lies on the island of Suomenlinna and serves as a museum during the summer.
