The Kobben class (also known as Type 207) is a customized version of the German Type 205 submarine. Fifteen vessels of this class were built for use by the Royal Norwegian Navy in the 1960s. The class later saw service with Denmark and Poland. The boats have since been withdrawn from service in the Norwegian and Danish navies. The Polish Navy operated two Kobben-class submarines (Bielik, Sęp) until 2021.[1][2]
