SMS Goeben was a Moltke-class battlecruiser of the Imperial German Navy, launched in 1911 and commissioned in 1912. She measured approximately 186.6 meters (612 feet 2 inches) in length overall, with a beam of 29.4 meters (96 feet) and a draft of 9.19 meters (30 feet 2 inches) fully loaded. Displacing around 22,979 tons normally and up to 25,400 tons at full load, Goeben featured a long forecastle deck extending most of the ship's length, with a superstructure comprising two conning towers—one forward and larger, one aft—and two pole masts for signaling and observation. Her propulsion system consisted of four Parsons steam turbines driving four screw propellers, powered by twenty-four coal-fired Schulz-Thornycroft water-tube boilers, rated at 51,289 shaft horsepower. This enabled her to reach speeds exceeding 25.5 knots, with a range of approximately 4,120 nautical miles at 14 knots. Armament included ten 28 cm (11-inch) SK L/50 guns in five twin turrets, secondary armament of twelve 15 cm (5.9-inch) guns, and twelve 8.8 cm (3.5-inch) guns for defense against torpedo boats. She was also equipped with four submerged 50 cm (20-inch) torpedo tubes. Her armor was constructed of Krupp cemented steel, with a belt up to 280 mm (11 inches) in thickness amidships, tapering to 76 mm (3 inches) at the ends. The main gun turrets’ faces were protected by 230 mm (9.1 inches) of armor, and the barbettes supporting them were similarly protected. Constructed by Blohm & Voss in Hamburg, her keel was laid in August 1909, and she was launched in March 1911. After fitting out, she was commissioned in July 1912 and initially served in the Mediterranean, patrolling during the Balkan Wars. Following the outbreak of World War I, she participated in bombardments in North Africa and the Black Sea, and was transferred to the Ottoman Empire in August 1914, where she was renamed Yavuz Sultan Selim, serving as the flagship of the Ottoman Navy. She played a significant role in bringing Turkey into the war and engaged Russian forces in the Black Sea, including the notable Battle of Imbros in 1918, during which she sank British monitors but was heavily damaged by mines. Yavuz remained active through the interwar period, was renamed multiple times, and served as Turkey’s flagship until her decommissioning in 1950. She was the last surviving ship built by the Imperial German Navy and the longest-serving dreadnought-type vessel worldwide. Scrapped in 1973, her legacy includes preserved parts and artifacts, marking her as a historically significant vessel for maritime history.
