These large ships belonged to an era when destroyers were ordered by the flotilla. Sixteen Tribals were built for the Royal Navy and twenty-seven across all operators. The Battle-class total is given from memory as about twenty-six ships. Ordering at that scale spread design effort and operational risk across many hulls, giving the navy more flexibility than a modern escort force whose total size can be smaller than one historical class.

Flotilla-scale construction enabled larger destroyers
The Royal Navy could accept large destroyers because it still built them in substantial classes: sixteen British Tribals and about twenty-six Battle-class ships spread design effort across a large fleet.
