Barbaros Hayreddin was sunk in 1915. Turgut Reis survived the conflict and was scrapped in the 1950s. Of the three planned Reşadiye-class ships, only one, Reşadiye, was ever built, with the rest being cancelled just before the war. Reşadiye was one of the ships seized by the British in August 1914. Sultân Osmân-ı Evvel, which had been bought from Brazil in 1913, was also seized by Britain in August 1914. The last battleship in the Ottoman Navy, Yavûz Sultân Selîm, survived the war and was scrapped in 1973. Key Abdül Kadir Abdül Kadir was the first Ottoman pre-dreadnought battleship to be constructed. She was laid down in 1892 at the beginning of a small-scale expansion of the Ottoman Navy. Work slowed down considerably once she was framed. By the early 1900s the only progress that had been made was the addition of armor plating around her keel. Once that was finished, work ceased. Construction was planned to resume in 1904 but by that time her keel blocks, which were used to prevent hogging and sagging, had shifted and the ship was considered a total loss. She was scrapped on the slipway in 1914. Barbaros Hayreddin and Turgut Reis The Ottoman battleships Barbaros Hayreddin and Turgut Reis were originally named SMS Kurfürst Friedrich Wilhelm and SMS Weissenburg, respectively. They were members of the German , the first class of ocean-going battleships built for the German navy. Two other ships of the class were constructed: Brandenburg and Wörth. Of the four, Kurfürst Friedrich Wilhelm and Weissenburg were more advanced in that their armor was composed of higher-quality steel. Kurfürst Friedrich Wilhelm and Weissenburg were sold to the Ottoman Navy in 1910 and renamed Barbaros Hayreddin and Turgut Reis, respectively. The two battleships saw very little service in the Italo-Turkish War and were mostly used to defend the Dardanelles from any Italian naval attacks. Barbaros Hayreddin and Turgut Reis saw heavy service during the Balkan Wars however, failing in two attempts to break the Greek naval blockade of the Dardanelles in December 1912 and January 1913, and providing artillery support to Ottoman ground forces in Thrace. On 8 August 1915, during World War I, Barbaros Hayreddin was torpedoed and sunk off the Dardanelles by the British submarine , with heavy loss of life. Turgut Reis was largely inactive during World War I, in part due to her slow speed. By 1924, Turgut Reis
