SM U-27 or U-XXVII was the lead boat of the U-27 class of U-boats or submarines for the Austro-Hungarian Navy. U-27 was built by the Austrian firm of Cantiere Navale Triestino (CNT) at the Pola Navy Yard and launched on 19 October 1916. She was commissioned on 24 February 1917.
She had a single hull and was just over 121 feet (37 m) in length. She displaced nearly 265 metric tons (261 long tons) when surfaced and over 300 metric tons (295 long tons) when submerged. Her two diesel engines moved her at up to 9 knots (17 km/h) on the surface, while her twin electric motors propelled her at up to 7.5 knots (13.9 km/h) while underwater. She was armed with two bow torpedo tubes and could carry a load of up to four torpedoes. She was also equipped with a 75 mm (3.0 in) deck gun and a machine gun.
During her service career, U-27 sank the British destroyer Phoenix, damaged the Japanese destroyer Sakaki, and sank or captured 34 other ships totaling 14,325 GRT. U-27 was surrendered at Pola at war's end and handed over to Italy as a war reparation in 1919. She was broken up the following year. Conway's All the World's Fighting Ships 1906–1921 calls U-27 Austria-Hungary's "most successful submarine".
