HMS Alexandra built by Chatham Dockyard and launched 7th April 
                  1875. Sold for breaking up 6th October 1908.
                HMS 
                  Alexandra was the last British battleship to carry her main 
                  armament wholly below decks; she was one of only two British 
                  ships to mount guns of 11-inch (280 mm) calibre, the other being 
                  HMS Temeraire.
                She 
                  was the first British warship to be powered by vertical compound 
                  engines, carrying cylindrical high-pressure boilers with a working 
                  pressure of 60 pounds-force per square inch, as compared to 
                  rectangular boilers working at 30 lbf/inch pressure mounted 
                  in earlier ships. 
                It 
                  had been intended to call the ship HMS Superb, but the name 
                  was changed at her launching, which was undertaken by Her Royal 
                  Highness the Princess of Wales, who was later Queen Alexandra. 
                  She was the first British ironclad to be launched by a member 
                  of the Royal Family; the Duke and Duchess of Edinburgh, the 
                  Duke and Duchess of Teck and the Duke of Cambridge were also 
                  present.
                She 
                  was commissioned at Chatham on 2nd January 1877 as flagship, 
                  Mediterranean Fleet, and held this position continuously until 
                  1889. She was the flagship of Admiral Hornby in his passage 
                  through the Dardanelles during the Russian war scare of 1878. 
                  She ran aground in bad weather at the narrowest part of the 
                  straight; she was towed off by HMS Sultan in time to lead the 
                  squadron to Constaninople.
                She 
                  was present at the bombardment of Alexandria in 1882; in this 
                  action the Admiral's flag was shifted to HMS Invincible, as 
                  she was of shallower draught and could sail closer to shore. 
                  In 1886, the Duke of Edinburgh hoisted his flag on board, and 
                  the Prince of Wales, later King George V, joined as a lieutenant. 
                  She paid off in 1889 for modernisation. In 1891, she was flagship 
                  of the reserve at Portland, and remained so until 1901. Her 
                  last sea-time was as flagship of the "B" fleet in 
                  the manoevres of 1900. In 1903 she became a mechanical training 
                  ship, and she was sold in 1908.
