Against a proposed sixteen-gun Belfast or Edinburgh, Brooklyn gave up one barrel but spread its battery across an extra turret. Losing one triple mount would remove a smaller share of the total battery than losing one quadruple mount, although the British arrangement could be considered more balanced. The comparison also places Brooklyn beside Japan's Mogami class as part of the international response to treaty limits. American-built Parsons geared turbines illustrate a parallel preference for proven machinery when reliability mattered to a fast, globally deployable cruiser.
