HMS Vanguard was a British
fast battleship built during the
Second World War and
commissioned after the war. She was the only ship of her class, the biggest and fastest of the
Royal Navy's
battleships, and the last battleship to be
launched in the world. Work on the ship's design commenced before the war because the Royal Navy anticipated being outnumbered by the combined German and Japanese battleships in the early 1940s. The British had enough 15-inch (381 mm) guns and turrets in storage to allow one ship of a modified
Lion-class battleship design to be completed faster than the ships of that class that had already been
laid down. Work on
Vanguard was started and stopped several times during the war and even after construction had begun, her design was revised several times to reflect war experience. These stoppages and changes prevented her from being completed during the war.
Vanguard's first task after completing her
sea trial at the end of 1946 was, early the next year, to convey
King George VI and his family on the first Royal Tour of
South Africa by a reigning monarch. While refitting after her return, she was selected for another
Royal Tour of Australia and New Zealand in 1948. This was cancelled due to King George's declining health and
Vanguard briefly became flagship of the
Mediterranean Fleet in early 1949. After her return home in mid-1949, she became flagship of the
Home Fleet Training Squadron. Throughout her career, the battleship usually served as the flagship of any unit to which she was assigned. During the early 1950s,
Vanguard was involved in a number of training exercises with
NATO forces. In 1953 she participated in Queen
Elizabeth II's
Coronation Review. While she was refitting in 1955, the
Admiralty announced that the ship was going to be put into
reserve upon completion of the work.
Vanguard was sold for
scrap and was broken up beginning in 1960.
