Dido's place in a destroyer attack and carrier screen

In a surface attack, Tribal-class destroyers could form the spearhead while a Dido followed with heavier fire to suppress resistance and help the torpedo ships close. The cruiser was designed with enough speed and maneuverability to work directly with those flotillas. Around a carrier, especially at night, the same ship could act as a close guard against enemy destroyers or cruisers trying to penetrate the screen. Its 5.25-inch battery could engage both aircraft and light surface forces, while two triple 21-inch torpedo sets offered a threat to heavier ships. This formation-level role explains why the Royal Navy called Dido a screening cruiser rather than defining it solely by anti-aircraft fire.
