معاهدة سلام
In January 1945, the Allies' Commission responsible for monitoring the observance of the Peace treaty ordered the Finnish submarines to be disarmed, and in 1947 according to the terms of the Paris Peace Treaty, the Finnish Defence Forces were forbidden to have any submarines. The Finnish submarines "Vetehinen", "Vesihiisi", "Iku-Turso", and "Saukko" were sold to Belgium to be scrapped in 1953. "Vesikko" was spared because the Finnish Defence Forces hoped that Finland could in future gain permission to use submarines again, and "Vesikko" was then meant to be used for training purposes. "Vesikko" was stored at the Valmet Oy dock in Katajanokka district in Helsinki.
