The Duncan-class battleships built 1901-1903 were predreadnought battleships of the Royal Navy. From 1889, Britains "rank as a first-class power was bound up with its Mediterranean position" and these lightly armoured fast ships were intended to help meet combined Russian and French threats. Their period of maximum operational significance was short. By 1904, Britain had formed the Entente cordiale with France whilst Russia was decisively defeated at the Tsushima the following year. This battle led to the design of HMS Dreadnought launched 1906 which eclipsed the Duncans and all previous ships.
