The British heavy cruiser HMS Cornwall was one of the Royal Navy’s County-class cruisers built during the interwar period. Commissioned in 1928, she was designed under the limitations of the Washington Naval Treaty, which restricted the size and armament of cruisers. As a result, Cornwall displaced around 10,000 tons and carried eight 8-inch guns mounted in four twin turrets.

Cornwall intercepted and destroyed the German auxiliary cruiser Pinguin in May 1941.
