The Delfinen-class submarines were the first class of submarines constructed for the Royal Danish Navy following World War II. They were designed and built within Denmark, with first three boats of the class financed by Denmark. The fourth was financed by the United States (where it was known as SS-554) under the Cost Share program. Constructed between 1956 and 1963, the class comprising four submarines (Delfinen, Spækhuggeren, Tumleren and Springeren) entered service in 1961 and the last taken out of service in 1990. Replaced by the Norwegian Kobben class, three of them were scrapped while a fourth was converted into a museum ship and remains on display at the Aalborg Maritime Museum.
