Why did the Royal Navy build Crown Colony and Dido cruisers instead of simply ordering more Towns?
Short answerCrown Colonies were simplified Towns suited to wartime production, while Didos were intended to meet the coming air threat.
NotesThe Royal Navy did not simply order more Town-class cruisers. The Crown Colony class is described as a stripped-down Town tailored for wartime production. The parallel Dido programme answered a different problem: the expected air war and the need for an anti-aircraft cruiser. Procurement split between a production-conscious conventional cruiser and a specialized response to air attack.
