Why the Atlanta class offered a better fleet-wide gun system

The Atlanta's shared five-inch destroyer weapon simplified supply and development compared with Britain's separate 5.25-inch system.

Question

Were the Dido and Atlanta classes essentially large destroyers, and which was preferable?

Short answer

Atlanta is preferable because its interchangeable five-inch weapon supported fleet-wide standardization and simpler logistics.

Notes

Atlanta is preferable at the force level even if neither design is ideal. Its five-inch weapon was shared with American destroyers, so cruiser construction reinforced a fleet-wide gun and ammunition system. Britain's simultaneous use of 5.25-, 4.7-, 4.5-, and 4-inch weapons multiplied supply, maintenance, and training burdens. A slightly less capable universal weapon could therefore generate more combat power across the fleet than several locally superior but incompatible systems.
