Finnish submarine Iku-Turso

Iku-Turso was a 500-tonne submarine that served in the Finnish Navy during the Second World War. It was launched in May 1931 and was named after a Finnish sea monster, Iku-Turso. Built by the Crichton-Vulcan shipyard in Turku according to project developed by "Ivs" . Scrapped in 1953.

Combat history

On 7 July 1941 the Iku-Turso under Lt-Cdr Pekkanen and the Vetehinen laid mines east of the island of Mohni/Ekholm.

On 27 October 1942, after unsuccessfully attacking a Soviet Shchuka class submarine with 20 mm Madsen cannon in poor visibility the Iku-Turso later came across and torpedoed another Soviet Shchuka class submarine. After torpedo impact the target disappeared. On impact site Finnish submarine located a large oil spill with even more oil still pluming to the surface. Submarine's identity has later been contested as several Soviet submarines of Shchuka class were lost at that time in the area but most likely candidates are either Shch-320 or perhaps even more likely Shch-308. However Russian sources claim that the Shch-320 had been sunk by a mine earlier that month and that the initial unsuccessful attack by Iku Turso had been against Shch-307.
