T2 was a torpedo boat of the Royal Yugoslav Navy. Originally a 250t-class torpedo boat of the Austro-Hungarian Navy, commissioned on 11 August 1914 as 77T, she saw active service during World War I, performing convoy, patrol, escort, minesweeping and minelaying tasks, anti-submarine operations, and shore bombardment missions. Present in the Bocche di Cattaro during the short-lived mutiny by Austro-Hungarian sailors in early February 1918, members of her crew raised the red flag but took no other mutinous actions. The boat was part of the escort force for the Austro-Hungarian dreadnought Szent István when that ship was sunk by Italian torpedo boats in June 1918. Following Austria-Hungary's defeat in 1918, the boat was allocated to the Navy of the Kingdom of Serbs, Croats and Slovenes, which became the Royal Yugoslav Navy in 1921, and was renamed T2. During the interwar period, Yugoslav naval activity was limited by reduced budgets. Worn out after twenty-five years of service, T2 was scrapped in 1939.
