HMS Britannia was a King Edward VII-class pre-dreadnought battleship of the Royal Navy. She was named after Britannia, the Latin name of Great Britain under Roman rule. After commissioning in September 1906, she served briefly with the Atlantic and Channel Fleets before joining the Home Fleet. In 1912, she, along with her sister ships of the King Edward VII class, was assigned to the 3rd Battle Squadron but in June 1913, she returned to duties with the Home Fleet.
When the First World War broke out, Britannia was transferred back to the 3rd Battle Squadron, which was part of the Grand Fleet. In 1916, she was attached to the 2nd Detached Squadron, then serving in the Adriatic Sea. After a refit in 1917, she conducted patrol and convoy escort duties in the Atlantic. On 9 November 1918, just two days before the end of the war, she was torpedoed by a German submarine off Cape Trafalgar and sank with the loss of 50 men.
HMS Britannia was built at Portsmouth Dockyard. She was laid down on 4 February 1904, launched on 10 December 1904, and completed in September 1906.
Six ships and a shore establishment of the Royal Navy have borne the name HMS Britannia, after Britannia, the goddess and personification of Great Britain:
HMS Prince of Wales was one of six 121-gun screw-propelled first-rate three-decker line-of-battle ships of the Royal Navy. She was launched on 25 January 1860.
In 1869 she was renamed HMS Britannia and under that name served at Dartmouth as a cadet training ship until 1905.
The Prince of Wales was originally a 3,186 ton 120 gun design by John Edye and Isaac Watts for a modified Queen-class sailing line-of-battle ship. She was laid down at Portsmouth on 10 June 1848, though she was not formally ordered until 29 June, and the design was approved on 28 July 1848.
In 1849, the Royal Navy started ordering screw line-of-battle ships starting with the Agamemnon. It is possible that construction of Prince of Wales was suspended, as screw line-of-battle ships laid down after her, were completed before her. Prince of Wales was reordered to complete as a 121 gun screw line-of-battle ship on 9 April 1856, conversion work started on 27 October 1856. Her half-sisters Duke of Wellington and Royal Sovereign were lengthened with an extra 23 ft amidships and 8 ft in the run, and originally it was intended that Marlborough and Prince of Wales would be converted to the same plans, but they were further lengthened during construction.
HMS Britannia was a 100-gun first rate ship of the line of the Royal Navy, built by Phineas Pett II at Chatham Dockyard, and launched in 1682. In 1705 she took on board Charles III of Spain, when on her way to Catalonia
In 1715, Britannia was ordered to be taken to pieces and rebuilt at Woolwich Dockyard, from where she relaunched on 30 October 1719, again as a 100-gun first rate.
Britannia was placed on harbour service in 1745, and was broken up in 1749.
She was captained from 1734 to 1736 by Sir Tancred Robinson.
