Ship project history: Dido class cruisers have been intended for service with squadrons as AA cruisers for escort of new battleships of King George V class and aircraft carriers of Illustrious class. The design was based on a basis of earlier built cruisers of Arethusa class with new armament consisting of ten 133mm guns in five universal mounts (3 fwd and 2 aft), unified with standing on King George V class, and two quadruple pom-poms. Cruisers were not intended for self-supporting operations on enemy sea communications (Arethusa was put also this task) and a fuel stock in comparison with a prototype was decreased. The design has appeared successful, and under 1936, 1937 and 1938 Estimates 10 ships have been ordered. 6 more ships (including 5 under changed design) have ordered under the War Emergency program. Production of twin 133mm mounts lagged behind from hull building, and part of cruisers were completed with 8 such guns (Dido, Bonaventure and Phoebe) or with 4 2 114mm mounts (Charybdis and Scylla). Fwd superstructure of latter pair had increased because of non-standard artillery: 114mm mounts demanded additional shifting room. Usage of heavy unitary 114mm cartridge did service of artillerymen on Charybdis and Scylla especially hard.

Protection: Armoured belt protected machinery spaces and extended up to upper deck level abreast boiler rooms and fore engine room and to main deck level abreast aft engine room. Magazines had 76mm sides. Armoured deck was 25mm thick over machinery and steering gear and 51mm over magazines.
