context_page_description: The Vetehinen-class submarine was a Finnish 500 tonne submarine class of three vessels that was designed and built in the 1920s and early 1930s. The Vetehinen class served in the Finnish Navy during World War II. The class was designed by Dutch dummy company Ingenieurskantoor voor Scheepsbouw den Haag and built by the Finnish Crichton-Vulcan shipyard in Turku. The class was based on the German World War I Type UB III and Type UC III submarines and served as prototype for Type VII submarines.
  The word vetehinen means a merman. Vetehinen-class submarines were designed as minelaying submarines and were built with mineshafts for 20 mines. Submarines had special inner rails for two torpedo tubes to enable 450 mm torpedoes to be used instead of the 533 mm torpedoes.
