Delfinen-class Submarine
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 (, , and ) entered service in 1961 and the last taken out of service in 1990. Replaced by the Norwegian , three of them were Ship breaking, scrapped while a fourth was converted into a museum ship and remains on display at the Aalborg Maritime Museum.

The class is sometimes known as the ''Undine'' class, after the first submarine built. A further development was the British V-class submarine of 1942. Background The Royal Navy was limited to no more than of submarines by the London Naval Treaty of 1930. The tonnage limit led to proposals for smaller submarines which was also prompted by trials with larger submarines demonstrating that they were easier to find and lacked manoeuvrability. By coincidence the First World War-vintage H-class submarines used for training in anti-submarine warfare were reaching the end of their useful service. The Rear-Admiral Submarines, Noel Laurence, wanted a class of small, inexpensive boats for training, armed with torpedoes for short-range patrols. In March 1934 wrote a specification for a "Small, Simple, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
