The Varna was a Sultan Makhmud-class ship of the line built for the Imperial Russian Navy's Black Sea Fleet during the late 1830s and early 1840s. Constructed at the I. D. Vorobyov shipyard in Nikolaev, her keel was laid down on October 4, 1838, and she was launched on July 26, 1842. The vessel measured approximately 197 feet 4 inches (60.15 meters) in length, with a beam of 52 feet (16 meters), and a draft ranging from 23 feet 8 inches (7.21 meters) to 26 feet 7 inches (8.10 meters). Displacing 3,790 metric tons (about 3,730 long tons), Varna had a burthen of around 2,500 tons. Her hull featured a round stern, a design choice intended to enhance structural strength. Armament-wise, Varna was equipped with a formidable battery typical of her class. Her main guns consisted of twenty-six 36-pounder long guns on the lower gun deck and thirty-two 36-pound short-barreled guns on the upper deck. Additionally, she carried various smaller guns, including twenty 24-pound gunnades, two 24-pound carronades, six 18-pound carronades, two 12-pound carronades, and two 8-pound carronades. During her service, she underwent modifications; in 1853, all carronades were removed, and in 1854, six 18-pound short-barreled guns were added. Varna's operational history was relatively uneventful, primarily involving routine peacetime activities. She helped transport the 13th Division of the Russian Army from Sevastopol to Odessa in 1843. After periods in reserve, she was recommissioned in 1852. During the Crimean War, she participated in transporting soldiers to the Caucasus but was unable to join the Battle of Sinop in November 1853 due to the need for repairs. Afterward, she remained in Sevastopol, where she was scuttled on September 11, 1854, as a blockship to prevent the entry of Anglo-French forces into the harbor during the siege of Sevastopol. The Varna exemplifies Russia's naval expansion efforts in the Black Sea during a period of rising tensions with Britain and France, serving primarily in a defensive capacity during her active years.
