Project history

The light cruisers ordered under the 1914-15 Programme were repeats of the Calliope, with the same layout. Only the Cambrian, last to be completed, incorporated the improved layout of the earlier class: 1 152mm gun in place of the sided 2 102mm on the forecastle. The other three were brought up to the same standard in 1916-17, and among other improvements a tripod with light director replaced the pole foremast.

Protection

Armoured belt protected ship at full length, its thickness was 76mm abreast machinery spaces (51mm armour on 25mm plating), 51mm (38mm armour on 13mm plating) aft and 38mm (25mm armour on 13mm plating) fore. Belt was closed by aft 25mm bulkhead near stern. It extended to main deck (and to upper deck abreast machinery). Machinery and steering gear were covered by 25mm deck.
