Faced with carrier aircraft approaching from any bearing in the open ocean, the U.S. Navy needed light cruisers able to defend a formation as well as fight surface opponents. Cleveland adapted the Brooklyn idea by giving up some six-inch armament for much more five-inch fire, drawing on the Atlanta approach to air defence. The remaining six-inch guns retained useful volume against destroyers and other cruisers, while the dual-purpose battery strengthened the fleet's layered protection. At 32.5 knots, Cleveland was a practical general-purpose design for Pacific carrier warfare.

Cleveland as a general-purpose wartime cruiser
Cleveland trades part of the Brooklyn-style six-inch battery for much stronger dual-purpose fire while retaining speed and surface-fighting value.
