The Yugoslav torpedo boat T5 was a sea-going torpedo boat operated by the Royal Yugoslav Navy between 1921 and 1941. Originally 87 F, a 250t-class torpedo boat of the Austro-Hungarian Navy commissioned on 25 October 1915 during World War I, she was armed with two 66 mm (2.6 in) guns and four 450 mm (17.7 in) torpedo tubes. Following Austria-Hungary's defeat in 1918, 87 F was allocated to what became the Royal Yugoslav Navy, and was renamed T5. The ship was captured by the Italians during the German-led Axis invasion of Yugoslavia in April 1941. After her main armament was modernised, she served with the Royal Italian Navy under the Yugoslav designation, conducting coastal and second-line escort duties in the Adriatic Sea. Following the Italian capitulation in September 1943, the ship was returned to the Royal Yugoslav Navy-in-exile and served as T5. At the end of the war she was transferred to the new Yugoslav Navy and served as Cer, and in 1962 was broken up. (Full article...)
