SM ''U-67'' was a Type U 66 submarine or U-boat for the German Imperial Navy ((ドイツ語:Kaiserliche Marine)) during the First World War. She had been laid down in November 1913 as ''U-8'' the second boat of the ''U-7'' class for the Austro-Hungarian Navy ((ドイツ語:Kaiserliche und Königliche Kriegsmarine ''or'' K.u.K. Kriegsmarine)) but was sold to Germany, along with the others in her class, in November 1914. The submarine was ordered as ''U-8'' from Germaniawerft of Kiel as the second of five boats of the ''U-7'' class for the Austro-Hungarian Navy. After the outbreak of World War I in August 1914, the Austro-Hungarian Navy became convinced that none of the submarines of the class could be delivered to the Adriatic via Gibraltar. As a consequence, the entire class, including ''U-8'', was sold to the German Imperial Navy in November 1914. Under German control, the class became known as the ''U 66'' type and the boats were renumbered; ''U-8'' became ''U-67'', and all were redesigned and reconstructed to German specifications. ''U-67'' was launched in May 1915 and commissioned in August. As completed, she displaced , surfaced, and , submerged. The boat was long and was armed with five torpedo tubes and a deck gun. A part of the IV Flottilla throughout the war, ''U-67'' sank 18 ships with a combined gross register tonnage (GRT) of 39,937 in thirteen war patrols. She also damaged three other ships of . On 20 November 1918, nine days after the Armistice, ''U-67'' was surrendered to the British. She was broken up in 1921 at Fareham. == Design and construction == After the Austro-Hungarian Navy had competitively evaluated three foreign submarine designs, it selected the Germaniawerft 506d design, also known as the Type UD, for its new ''U-7'' class of five submarines.〔Gardiner, p. 340.〕 The Navy ordered five boats on 1 February 1913.〔Gardiner, p. 343.〕 The ''U-7'' class was seen by the Austro-Hungarian Navy as an improved version of its ''U-3'' class, which was also a Germaniawerft design.〔〔The ''U-3''-class submarines, however, were less than half the displacement and nearly shorter than the ''U-7'' design. See: Gardiner, pp. 342–43.〕 As designed for the Austro-Hungarian Navy, the boats were to displace on the surface and while submerged. The doubled-hulled boats were to be long overall with a beam of and a draft of . The Austrian specifications called for two shafts with twin diesel engines ( total) for surface running at up to , and twin electric motors ( total) for a maximum of when submerged.〔 The boats were designed with five torpedo tubes; four located in the bow, one in the stern. The boats' armament was to also include a single L/26 deck gun.〔 ''U-8'' and sister boat were both laid down on 1 November 1913, the first two boats of the class begun.〔Helgason, Guðmundur.

Retrieved on 9 December 2008.〕 Her construction was slated to be complete within 29 to 33 months.〔 Neither ''U-8'' nor any of her sister boats were complete when World War I began in August 1914.〔 With the boats under construction at Kiel, the Austrians became convinced that it would be impossible to take delivery of the boats, which would need to be towed into the Mediterranean past Gibraltar, a British territory.〔〔The Austro-Hungarian Navy's Germaniawerft-built ''U-3'' class boats had been towed from Kiel to Pola via Gibraltar in 1909. See: Sieche, p. 19.〕 As a result, ''U-8'' and her four sisters were sold to the Imperial German Navy on 28 November 1914.〔Gardiner, p. 177.〕〔In April 1915, just five months later, the German successfully entered the Mediterranean through the Straits of Gibraltar, proving that delivery would have been possible after all. See: Gardiner, p. 343.〕 ''U-8'' was renumbered by the Germans as ''U-67'' when her class was redesignated as the Type U 66. The Imperial German Navy had the submarines redesigned and reconstructed to German standards, which increased the surface displacement by and the submerged by . The torpedo load was increased by a third, from 9 to 12, and the deck gun was upgraded from the gun originally specified to an one.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SM U-67」の詳細全文を読む スポンサード リンク
