Varna was a built for the Imperial Russian Navy's Black Sea Fleet in the late 1830s and early 1840s. The ship had an uneventful career, apart from routine peacetime operations in the 1840s, interrupted by periods in reserve. In October 1853, she helped carry soldiers to the Caucasus to strengthen the Russian position there at the start of the Crimean War. In need of repairs, she was unable to take part in the Battle of Sinop in November, and thereafter remained in Sevastopol during the siege of the city. Her crew was sent ashore to reinforce the defenses and "Varna" was scuttled as a blockship in 1854 to bar the harbor entrance to French and British warships.
