''Conway's All the World's Fighting Ships, 1906–1921'' calls ''U-27'' Austria-Hungary's "most successful submarine". == Design and construction == Austria-Hungary's U-boat fleet was largely obsolete at the outbreak of World War I.〔Gardiner, p. 341.〕 The Austro-Hungarian Navy satisfied its most urgent needs by purchasing five Type UB I submarines that comprised the from Germany,〔Gardiner, p. 343.〕 by raising and recommissioning the sunken French submarine ''Curie'' as ,〔〔''Curie'' had been caught in an anti-submarine net while trying to enter the harbor at Pola on 20 December 1914.

She was also equipped with a 75 mm/26 (3.0 in) deck gun and an machine gun.〔 After intricate political negotiations to allocate production of the class between Austrian and Hungarian firms,〔 ''U-27'' was ordered from Cantiere Navale Triestino (CNT) on 12 October 1915.〔 She was laid down by early 1916 at the Pola Navy Yard,〔By this time, the CNT shipyards at Monfalcone had been overrun by the Italian Army.
