Were the Atlanta and Dido classes cruisers designed as destroyer killers?
Short answerThey could act as destroyer killers, but their primary role was that of anti-aircraft cruisers.
NotesThe Atlanta and Dido classes could serve as destroyer killers, although their principal role was anti-aircraft defense. Their effectiveness against destroyers does not erase that fleet function. A ship can perform a useful secondary task without being classified around it. These two classes offer a concise example of the difference between formal role and additional capability.
