The Town and Brooklyn classes answer different operational requirements despite their superficial resemblance. Brooklyn concentrates fifteen six-inch guns and places aircraft aft for a US Navy centered on the battle fleet and a Pacific fleet action. Town sacrifices a fifth turret for a protected central hangar because Royal Navy cruisers were more likely to patrol independently and use aviation for sea control far from support. The proposed quadruple six-inch mounting could have given Belfast and Edinburgh sixteen guns, while fitting three such turrets to the later Crown Colony class could have retained twelve. These allocations of weapons, protected volume, and aircraft facilities make national doctrine visible.

Similar six-inch cruisers allocate guns and aircraft differently because Britain expected independent sea-control work while the United States emphasized fleet action.
