SM ''UB-14'' was a German Type UB I submarine or U-boat in the German Imperial Navy ((ドイツ語:Kaiserliche Marine)) during World War I. The submarine was also known by the Austro-Hungarian Navy designation of SM ''U-26''. ''UB-14'' was ordered in October 1914 and was laid down at the AG Weser shipyard in Bremen in November. ''UB-14'' was a little under in length and displaced between , depending on whether surfaced or submerged. She carried two torpedoes for her two bow torpedo tubes and was also armed with a deck-mounted machine gun. ''UB-14'' was broken into sections and shipped by rail to the Austrian port Pola for reassembly. She was launched and commissioned in March 1915 as SM ''UB-14'' in the German Imperial Navy under the command of Oberleutnant zur See Heino von Heimburg.〔"SM" stands for "Seiner Majestät" ((英語:His Majesty's)) and combined with the ''U'' for ''Unterseeboot'' would be translated as ''His Majesty's Submarine''.〕 Because Germany and Italy were not yet at war when ''UB-14'' entered service, she was transferred in name only to the Austro-Hungarian Navy. The submarine retained her German captain and crew, and remained under German command as a part of the ''Kaiserliche Marine''s Pola Flotilla. During her first patrol in the Adriatic, ''UB-14'' torpedoed and sank the . While traveling to Constantinople (present-day Istanbul) to join the Constantinople Flotilla, ''UB-14'' attacked two British troopships, sinking with heavy loss of life, and seriously damaging . All three of ''UB-14''s first victims were among the largest ships attacked by U-boats during the war. Although ''UB-14'' sank the British submarine in the Sea of Marmara in November 1915, she spent most of the rest of her career patrolling in the Black Sea. The U-boat had only limited success there, sinking only three ships through the end of the war. After the war ended, the submarine was disarmed at Sevastopol and surrendered at Malta in November 1918. ''UB-14'' was broken up in 1920. == Design and construction == After the German Army's rapid advance along the North Sea coast in the earliest stages of World War I, the German Imperial Navy found itself without suitable submarines that could be operated in the narrow and shallow seas off Flanders.〔Miller, pp. 46–47.〕〔Karau, p. 48.〕 Project 34, a design effort begun in mid-August 1914,〔 produced the Type UB I design: a small submarine that could be shipped by rail to a port of operations and quickly assembled. Constrained by railroad size limitations, the UB I design called for a boat about long and displacing about with two torpedo tubes.〔〔A further refinement of the design—replacing the torpedo tubes with mine chutes but changing little else—evolved into the Type UC I coastal minelaying submarine. See: Miller, p. 458.〕 ''UB-14'' was part of the initial allotment of seven submarines—numbered to —ordered on 15 October from AG Weser of Bremen, just shy of two months after planning for the class began.〔〔Williamson, p. 12.〕 ''UB-14'' was laid down by Weser in Bremen on 9 November.〔 As built, ''UB-14'' was long, abeam, and had a draft of . She had a single Körting 4-cylinder diesel engine for surface travel, and a single Siemens-Schuckert electric motor for underwater travel, both attached to a single propeller shaft. Her top speeds were , surfaced, and , submerged.〔 At more moderate speeds, she could sail up to on the surface before refueling, and up to submerged before recharging her batteries. Like all boats of the class, ''UB-14'' was rated to a diving depth of , and could completely submerge in 33 seconds. ''UB-14'' was armed with two torpedoes in two bow torpedo tubes. She was also outfitted for a single machine gun on deck. ''UB-14''s standard complement consisted of one officer and thirteen enlisted men.〔Karau, p. 49.〕 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 UB-14」の詳細全文を読む スポンサード リンク
