Commissioned in 1823, she saw service in the Mediterranean from 1830-1 and in 1841. She was decommissioned in 1843, before returning to service for the Crimean War, serving as flagship of Admiral Sir James Deans Dundas, commanding the British fleet in the Mediterranean and Black Sea from 1851–4.. She was engaged in the Bombardment of Sebastopol on 17 October 1854 during the Crimean War. On 14 November 1854, she was driven ashore on the Russian coast and was reported to have 5 feet (1.5 m) of water in her hold.
She returned to England at the beginning of 1855 and that year became a hospital ship at Portsmouth, then a cadet training ship in 1859. She was moved to Portland in 1862, then Dartmouth in 1863, where she served as residential barracks for cadets.
Generations of naval officers had their first taste of the navy aboard the two Britannias. Alumni included John Fisher, Percy Scott, John Jellicoe, Roger Keyes, William Boyle, Augustus Agar and King George V.
