Yugoslav submarine Hrabri

The Yugoslav submarine Hrabri was a submarine built by the Vickers-Armstrong Naval Yard, River Tyne, United Kingdom, for the Kingdom of Serbs, Croats and Slovenes (later Yugoslavia) and was launched in 1927. Her design was based on that of the British L-class submarine of World War I, and she was built using parts originally assembled for an L-class submarine that was never built. During the German-led Axis invasion of Yugoslavia in April 1941, she was captured by Italian forces. She was given the number N3 but was not commissioned and was subsequently scrapped due to her poor condition.

Description and construction
Hrabri was built for the Kingdom of Serbs, Croats and Slovenes (later Yugoslavia) by the Vickers-Armstrong Naval Yard, River Tyne, United Kingdom. Her design was based on that of the British L-class submarine of World War I, and she was built using parts originally assembled for HMAS L-67, which was never built. Along with her sister ship Nebojsa, she had an overall length of 72.05 m, a beam of 7.32 m, and a surfaced draught of 3.96 m. Her surfaced displacement was 1164 LT (1164 LT submerged), and her crew consisted of 45 officers and enlisted men. The ship had two shafts driven by two diesel engines or two electric motors. The diesel engines were rated at 2400 bhp and the electric motors at 1600 shp, and she was designed to reach a top speed of 15.7 kn under diesel power and 10 kn on her electric motors. Hrabri was armed with six bow-mounted 533 mm torpedo tubes, two 102 mm guns (one forward and one aft of the conning tower), and one machine gun.

Career and fate
Hrabri was launched in 1927 as the first submarine of the navy of the Kingdom of Serbs, Croats and Slovenes, which subsequently became the Royal Yugoslav Navy. During the German-led Axis invasion of Yugoslavia in April 1941, she was captured by Italian forces at the Bay of Kotor. She was given the number N3 but was not commissioned and was subsequently scrapped later that year due to her poor condition.
