The Sevastopol was the lead ship of the Gangut-class battleships of the Imperial Russian Navy, constructed before World War I. Laid down on June 16, 1909, at the Baltic Works in Saint Petersburg, she was launched on July 10, 1911, and commissioned on November 30, 1914. With a length overall of approximately 181.2 meters and a waterline length of about 180 meters, she had a beam of 26.9 meters and a draft of 8.99 meters, which was slightly deeper than her designed draft by 49 centimeters. Her displacement at load was approximately 24,800 tonnes, exceeding her designed displacement of 23,288 tonnes by over 1,500 tonnes. Sevastopol's propulsion system consisted of ten Parsons-type steam turbines, powered by twenty-five Yarrow boilers, producing a total of 52,000 shaft horsepower during trials and achieving speeds up to 24.1 knots. Her main armament comprised twelve 12-inch (305 mm) guns arranged in four triple turrets along her length, with a secondary battery of sixteen 4.7-inch guns in casemates and initially a single 3-inch anti-aircraft gun. She was also equipped with four submerged 17.7-inch torpedo tubes. During her service, she primarily performed defensive roles in the Gulf of Finland, training, and covering minelaying operations during World War I. She saw limited action, notably running aground in 1915 and suffering a magazine fire caused by a dropped charge, which resulted in casualties. After the February Revolution, her crew mutinied, and she later joined the Kronstadt rebellion in 1921, during which she was hit by German shells. Renamed Parizhskaya Kommuna in 1921, she was extensively refitted in the 1930s, including replacing her boilers, upgrading her guns, and modernizing her fire-control systems. She was transferred to the Black Sea Fleet in 1930, where she became the flagship. Her modifications included adding anti-torpedo bulges, improving stability, and reinforcing her deck armor. During World War II, she provided gunfire support during the Siege of Sevastopol until April 1942, after which she was withdrawn from combat and later served as a training ship until her decommissioning in 1956. She was scrapped in 1956–1957, marking her as a significant vessel in Russian naval history for her role as the first Russian dreadnought and her extensive wartime service.
