Yugoslav torpedo boat T7.
T7 was a sea-going torpedo boat operated by the Royal Yugoslav Navy between 1921 and 1941. Originally 96 F, a 250t-class torpedo boat commissioned on 23 November 1916 by the Austro-Hungarian Navy, she performed escort, minesweeping, anti-submarine and shore bombardment operations during World War I. Following Austria-Hungary's defeat in 1918, she was allocated to Yugoslavia and renamed T7. She was captured by the Italians during the Axis invasion of Yugoslavia in April 1941 and used for coastal and second-line tasks, after her main armament was modernised. Following the Italian capitulation in September 1943, she was captured by Germany and handed over to the Navy of the Independent State of Croatia, continuing to serve as T7. Her crew came under the influence of the Yugoslav Partisans, and were preparing to mutiny when the Germans intervened. She ran aground during a battle with British motor torpedo boats in June 1944 and was then destroyed.
