Gibraltar

Having learned that Japan and Germany were building heavy cruisers that surpassed the limits stipulated by the Washington Treaty, the British Admiralty began designing their own cruisers of the same type. In 1938, a project of a ship with a displacement of 20,000 tons and armed with nine or twelve 203–234 mm guns was presented. One of the armament options was the arrangement of three quadruple-gun turrets.
