Chesma was an 84-gun ship of the line built for the Black Sea Fleet of the Imperial Russian Navy in the 1840s. "Rostislav" carried a battery primarily consisting of tradition shot-firing guns, but she also carried four new shell-firing guns. The ship saw combat during the Crimean War at the Battle of Sinop against an Ottoman squadron in 1853, where the Russian shell guns proved to be decisive. The battle prompted Britain and France to intervene to support the Ottomans, leading the Russian fleet to withdraw to Sevastopol to avoid a battle with an Anglo-French fleet. "Chesma" helped to defend Sevastopol, supporting Russian ground forces during a battle in February 1855 before being disarmed to strengthen the city's defenses and then scuttled to block the harbor entrance to the Anglo-French fleet in August.
