The treaty limitations meant that fewer new battleships were launched from 1919–1939 than from 1905–1914. The treaties also inhibited development by putting maximum limits on the weights of ships and forced the Royal Navy into compromise designs for the "Nelson" and "King George V" classes. Designs like the projected British N3-class battleship continued the trend to larger ships with bigger guns and thicker armour, but never got off the drawing board. Those designs which were commissioned during this period were referred to as treaty battleships. After the Second World War, the Royal Navy's four surviving "King George V"-class ships were scrapped in 1957 and "Vanguard" followed in 1960. All other surviving British battleships had been sold or broken up by 1949.
