C-class light cruisers - sub-class Caledon
The Caledon class[edit]

The Caledon class were all ordered in December 1915 and commissioned in 1917. The ships retained the two funnels of the previous two sub-classes. Their propulsion was slightly different from the previous sub-classes. Their superstructure was also slightly altered. They had a main armament of five 6-inch (152 mm) guns and a secondary armament of two 3 in guns, as well as an AA armament of four 3 pounder guns. The surviving ships of the class saw World War II, undergoing a number of modifications along the way. Five Oerlikon 20 mm cannons were added to all ships. Caledon herself had a different armament, as she underwent an extensive rebuild to become an AA cruiser. She was armed with the effective 4-inch (102 mm) gun, of which she had twelve, two 40 mm Bofors and eight 20 mm Oerlikons.
