The last battleship ever built was a patchwork of First World War technology

In short: HMS Vanguard was the Royal Navy's final battleship, commissioned after the Second World War. To bypass the bottleneck of building new heavy guns, engineers repurposed 15-inch turrets originally designed for battlecruisers in 1917. This unique vessel served as a royal yacht and flagship before being scrapped in 1960.

Conceived as a stopgap measure, Vanguard was the only ship of her class. By 1939, the Royal Navy realized that the new Lion-class battleships would not be ready until 1943 due to the slow production of their 16-inch guns. To accelerate construction, designers utilized four twin 15-inch turrets salvaged from the battlecruisers Courageous and Glorious, which had been converted into aircraft carriers in the 1920s. This decision allowed the ship to be laid down in October 1941, though wartime labor shortages and constant design revisions—including a shift to a transom stern to improve speed—delayed her completion until May 1946.

Vanguard’s design was a living document of wartime lessons. After the loss of the Prince of Wales, engineers added watertight access trunks and increased the distance between propeller shafts to prevent total power failure from a single torpedo strike. Her armor was also heavily modified to resist modern threats, including 500-pound semi-armour-piercing bombs. Despite these upgrades, she was a product of a fading era. By the mid-1950s, the emergence of the Blackburn Buccaneer attack aircraft rendered the battleship's heavy guns obsolete against the Soviet Sverdlov-class cruisers she was intended to counter.

Beyond her military role, Vanguard served as a floating symbol of the British Empire. In 1947, she carried King George VI and his family on a historic tour of South Africa, requiring the conversion of the Admiral's suite and the removal of an anti-aircraft mount to create a saluting platform. She remained a flagship throughout her career, participating in NATO exercises and Queen Elizabeth II's 1953 Coronation Review. However, the cost of maintaining such a massive vessel—which displaced over 51,000 tons at deep load—became unsustainable. Following a final refit in 1955, she was placed in reserve and eventually sold for scrap in 1960, marking the end of the battleship age.
