HMS Caledon was a C-class light cruiser built for the Royal Navy during World War I. She was the name ship of the Caledon sub-class of the C class. She survived both world wars to be scrapped in 1948.

HMS Curacoa was a C-class light cruiser built for the Royal Navy during the First World War. She was one of the five ships of the Ceres sub-class and spent much of her career as a flagship. The ship was assigned to the Harwich Force during the war, but saw little action as she was completed less than a year before the war ended. Briefly assigned to the Atlantic Fleet in early 1919, Curacoa was deployed to the Baltic in May to support anti-Bolshevik forces during the British campaign in the Baltic during the Russian Civil War. Shortly thereafter the ship struck a naval mine and had to return home for repairs.
