''U-17'' was laid down in Germany in April 1915 and shipped in sections by rail to Pola in August, where she was assembled. She was delivered to the Austro-Hungarian Navy at the end of September and commissioned in October 1915. ''U-17'' primarily operated from Cattaro, patrolling off the Italian and Albanian coasts. The submarine had several opportunities to sink merchant ships and warships throughout the war, but sank only one Italian destroyer in July 1916 as part of an effort to disrupt the Otranto Barrage. At the end of the war, ''U-17'' was undergoing repairs at Pola. She was handed over to Italy as a war reparation and scrapped in 1920. == Design and construction == ''U-17'' was a small, coastal submarine that displaced surfaced and submerged.

In October 1916, ''U-17''s armament was supplemented with a 37 mm/23 (1.5 in) quick-firing (QF) gun. This gun was replaced by a 47 mm/23 (1.9 in) QF gun in November 1917.〔 ''U-17'' was ordered by the Austro-Hungarian Navy on 1 April 1915 and laid down at AG Weser in Bremen later that month.〔〔 When completed, the submarine was broken down into sections, loaded onto railcars, and shipped to the Austro-Hungarian Navy's main base at Pola on 30 August.〔 After completing the four-day journey,〔 the sections were riveted together.〔 Though there is no specific mention of how long it took for ''U-17''s sections to be assembled, a sister boat, the German Type UB I submarine ''UB-3'', shipped to Pola 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-17'' was delivered to the Austro-Hungarian Navy on 30 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-17 (Austria-Hungary)」の詳細全文を読む スポンサード リンク
