SM ''U-41'' or ''U-XLI'' was a ''U-27'' class U-boat or submarine for the Austro-Hungarian Navy. ''U-41'', built by the Austrian firm of Cantiere Navale Triestino (CNT) at the Pola Navy Yard, was launched in November 1917. When she was commissioned in February 1918, she became the last boat of her class to enter service. She was also the last domestically constructed Austro-Hungarian U-boat to enter service. She had a single hull just over in length. She displaced when surfaced and over when submerged. Her two diesel engines moved her at up to on the surface, while her twin electric motors propelled her at up to 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 deck gun and a machine gun. During a short service career marred by repeated engine breakdowns, ''U-41'' sank one ship, the French steamer ''Amiral Charner'' of . ''U-41'' was at Cattaro at war's end, and was ceded to France as a war reparation in 1920. She was towed to Bizerta and broken up within a year. == 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 as ,〔〔 had been caught in an anti-submarine net while trying to enter the harbor at Pola on 20 December 1914.

See: Gardiner, pp. 344, 354.〕 Once these steps had alleviated their most urgent needs,〔 the Austro-Hungarian Navy selected the German Type UB II design for its newest submarines in mid 1915.〔Halpern, p. 383.〕 The Germans were reluctant to allocate any of their wartime resources to Austro-Hungarian construction, but were willing to sell plans for up to six of the UB II boats to be constructed under license in Austria-Hungary.〔 The Navy agreed to the proposal and purchased the plans from AG Weser of Bremen,〔Baumgartner and Sieche, as excerpted (here ) (reprinted and translated into English by Sieche).

She was also equipped with a 75 mm/26 (3.0 in) deck gun and an machine gun.〔 ''U-41'' was ordered from Cantiere Navale Triestino (CNT) as a replacement for (which had been sunk in May 1916).〔 She was laid down on 23 February 1917 at the Pola Navy Yard.〔〔By this time, the CNT shipyards at Monfalcone had been overrun by the Italian Army.
