SM ''U-11'' or ''U-XI'' was a in the Austro-Hungarian Navy ((ドイツ語:Kaiserliche und Königliche Kriegsmarine ''or'' K.u.K. Kriegsmarine)) during World War I. She was originally a German Type UB I submarine commissioned into the German Imperial Navy ((ドイツ語:Kaiserliche Marine)) as SM ''UB-15''. SM ''UB-15'' was constructed in Germany and shipped by rail to Pola, where she was assembled and launched. She was commissioned into the German Imperial Navy in April and sank an Italian submarine in June. The boat was handed over to Austria-Hungary and commissioned as SM ''U-11'' on 14 June. In early 1916, ''U-11'' fired on a British submarine, but missed. After the end of the war, ''U-11'' was handed over to Italy as a war reparation and scrapped at Pola by 1920. == Design and construction == ''U-11'' was a small coastal submarine that displaced surfaced and submerged. She featured a single shaft, a single Körting diesel engine for surface running, and a single electric motor for submerged travel.〔 ''U-11'' was capable of up to while surfaced and while submerged at a diving depth of up to . She was designed for a crew of 17 officers and men.〔 ''U-11'' was equipped with two torpedo tubes located in the front and carried a complement of two torpedoes.〔 German Type UB I submarines were additionally equipped with a machine gun, but it is not clear from sources if ''U-11''a former German boatwas fitted with one, or if it was, retained it in Austro-Hungarian service. In October 1916, ''U-11''s armament was supplemented with a 66 mm/18 (2.6 in) gun.〔 ''UB-15'' was laid down on 9 November 1914 at AG Weser in Bremen. The submarine was shipped by rail in sections to Pola, where the sections were riveted together. There is no known surviving record of how long it took for UB-15's sections to be assembled. However, a similar ship (''UB-3'') was built in two weeks.〔Messimer, p. 126–27.〕 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-11 (Austria-Hungary)」の詳細全文を読む スポンサード リンク
