were completed during 1938-1939 and
were the most modern and powerful light cruisers with which the U.S.
began the war. The design arose out of the London Conference of
1930, where the U.S. reluctantly agreed to a freeze on further heavy cruiser construction.
This forced the U.S. Navy to turn to light cruiser construction. Though
design studies began as soon as the London Treaty was ratified, a final
design was not accepted until 1934, due to increased awareness of the
need for antiaircraft protection and the appearance of the Japanese Mogamis
with their (initial) armament of 15 6" guns.
The final design matched the enormous number of guns on the Mogamis and used a protection scheme similar to that of the New Orleans-class heavy cruisers, making them the best-protected modern light cruisers in the world (only the Mogamis came close). However, the Brooklyns proved somewhat structurally weak, and their machinery was not well dispersed. They could carry up to six seaplanes in their large hangers, but the usual complement was four.
