In the real world the Dido Class was armed with five twin 5.25" turrets, the same as fitted to the King George V battleships as secondary armament. However in this Alternate Universe the RN did not include the 5.25" gun in their armaments inventory. The twin 4.5 with bag and shell projectiles, not the fixed projectiles of that other RN, were the guns of choice.
The Dido type introduced the twin 4.5" turret with Dual Purpose capabilities to the Commonwealth cruiser forces. The lightweight turret and high rate of fire was not only useful against aircraft but also against enemy destroyers and other light craft. The rest of the armament was the standard 2pd pom pom with three quad mountings being fitted, then the new Oerlikon 20mm cannons in twin and single mountings were placed wherever space could be made for them, 24 barrels being fitted. The obligatory two sets of triple 21" torpedoes were fitted but these were the first things removed when topweight needed to be lost to fit the new weaponry and electronics that became available throughout the war.
The RN Dido class was a handy sized ship and fast enough to act with the destroyer flotillas. Minimal armour was fitted, most over the machinery spaces and a box armour system over the magazines. The Australis and Southern African designed ships were smaller and slower but carried just about as much armament.
While classed as cruisers, in the Commonwealth countries they were referred to just as Anti-Aircraft Ships.
Two of the RN Dido class were transferred to US dockyards to be completed when the severe shortage of material and weapons occurred during 1941. Lend Lease came at just the right time.
