SM ''U-16'' or ''U-XVI'' was a or U-boat of the Austro-Hungarian Navy ((ドイツ語:Kaiserliche und Königliche Kriegsmarine ''or'' K.u. K. Kriegsmarine)) during World War I. ''U-16'' was constructed in Germany and shipped by rail to Pula where she was assembled and completed in September 1915. She was commissioned in October 1915. For most of her career, ''U-16'' operated in the Adriatic out of Kotor patrolling off the Albanian coast. The U-boat sank one small sailing ship in November and seized another in December. ''U-16'' carried Field Marshal Svetozar Borojević of the Austro-Hungarian Army as an observer while performing diving tests after engine repairs in January 1916. A water leak in March flooded ''U-16''s batteries and put the U-boat out of action for about six weeks of repairs. While operating off Vlorë in mid-October 1916, ''U-16'' sank an Italian destroyer acting as a convoy escort. ''U-16'' was sunk in the ensuing action, but sources are not clear on the exact cause of her sinking. In all ''U-16'' sank three ships with a combined tonnage of 711. She was the only ''U-10''-class submarine sunk during the war. == Design and construction == ''U-16'' was a small, coastal submarine that displaced surfaced and submerged. She featured a single shaft, a single Daimler diesel engine for surface running, and a single electric motor for submerged travel.〔 ''U-16'' 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-16'' was equipped with two torpedo tubes located in the front and carried a complement of two torpedoes. Although most members of the class were outfitted with a 37 mm/23 (1.5 in) quick-firing (QF) gun to supplement their armament in October 1916, it is not known whether this upgrade had yet taken place on ''U-16'' by the time of her sinking during that month.〔 ''U-16'' was ordered by the Austro-Hungarian Navy on 1 April 1915 and laid down at AG Weser in Bremen on later in the month.〔〔 When completed, the submarine was broken down into sections, loaded onto railcars, and shipped on 20 August to the Austro-Hungarian Navy's main base at Pula.〔 After completing the eight-day journey,〔 the sections were riveted together.〔 Though there is no specific mention of how long it took for ''U-16''s sections to be assembled, a sister boat, the German Type UB I submarine ''UB-3'', shipped to Pula from Germany in mid-April 1915, was assembled in about two weeks.〔Messimer, p. 126–27.〕〔The Austro-Hungarian and the German Type UB I were virtually identical.〕 ''U-16'' was delivered to the Austro-Hungarian Navy on 29 September.〔 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-16 (Austria-Hungary)」の詳細全文を読む スポンサード リンク
