Battleships had been internationally perceived as the strategic
arms race focus since the
Washington Naval Conference of 1921. Countries unable to match the numbers of battleships maintained by the United States and the United Kingdom had built faster battleships so they might have the option of evading stronger fleets. Italy modernized
Conte di Cavour and
Giulio Cesare in 1937 with new engines increasing their speed to 28 knots. Germany completed the 31-knot battleships
Gneisenau in 1938 and
Scharnhorst in January 1939. For the first ten months of
World War II, the
Dunkerque-class battleships of
Force de Raid were among the few
Allied battleships available to counter the
Scharnhorst-class battleships. The
Royal Navy battle cruisers , , and , although older, were also generally competitive with Scharnhorst, in part due to upgrades between-the-wars, including increased horizontal protection in the first two. The Italian battleships
Vittorio Veneto and
Littorio were completed in April and May 1940.
Duilio was modernized to a speed of 27 knots in July, and
Andrea Doria completed similar modernization in October. The
German battleship Bismarck was completed in August. Britain's first modern battleship would not be completed until December 1940, and a British Defense Council subcommittee had concluded as recently as 1936 there was no justification for assuming aircraft could destroy battleships. This conclusion would be disproved by the
battle of Taranto in November, but
Winston Churchill remained focused on battleships as late as August 1941. ==History==
