 in the 1980s.

The Brooklyn-class ships were a strong influence on US cruiser design. Nearly all subsequent US cruisers, heavy and light, were directly or indirectly based on them.

Design

The Brooklyns arose from the London Naval Treaty
London Naval Treaty
The London Naval Treaty was an agreement between the United Kingdom, the Empire of Japan, France, Italy and the United States, signed on April 22, 1930, which regulated submarine warfare and limited naval shipbuilding. Ratifications were exchanged in London on October 27, 1930, and the treaty went...

s between 6.1 inches and 8 inches. The United States did not favor this outcome, being of the opinion that the heavier-gunned ships more suited its Pacific needs. Design started in 1930, with the first four of the class ordered in 1933 and an additional three ships in 1934. Basic criteria had been that speed and range should match heavy cruisers and, when the Japanese Mogami-class cruiser

s carrying fifteen six-inch main guns appeared, the new U.S. ships would match their weaponry. Various combinations of armor and power plants were tried in the efforts to stay below the Treaty 10,000 ton limit.

The six-inch guns were of a new design, the Mk 16 which could fire a 130-pound shell up to 26,100 yards (nearly 23,900 metres). The intention to mount 1.1 inch anti-aircraft guns was frustrated and the requirement was not fully met until 1943: interim solutions had to be accepted.

From 1942, the bridge structure was lowered and radar

 was fitted. Increased anti-aircraft weaponry was specified (four quadruple plus four twin 40 mm mountings) but not met. In practice there were varied mixes of 20 mm and 40 mm mountings, 28 40 mm (4x4, 6x2} and twenty 20 mm (10x2) being the most common.
