The '''''Brooklyn''-class cruiser''' was a [[ship class|class]] of nine [[light cruiser]]s built for the [[United States Navy]] between 1935 and 1938. Armed with five triple {{convert|6|in|mm|0|adj=on}} [[gun turret]]s (three forward, two aft), they mounted more main battery guns than any other standard US cruiser. The ''Brooklyn''-class ships were all [[Ship commissioning|commissioned]] between 1937 and 1939, in the time between the start of the [[Second Sino-Japanese War]] and before the [[invasion of Poland]]. They served extensively in both the [[Pacific Ocean|Pacific]] and [[Atlantic Ocean|Atlantic]] theaters during [[World War II]].

{{USS|Helena|CL-50|2}} was sunk in the [[Pacific War|Pacific]], and while some of the others were heavily damaged, the remaining ships of the class were [[Ship decommissioning|decommissioned]] shortly after the end of the war. Six were transferred to South American navies in 1951, where they served for many more years. One of these, {{ship|ARA|General Belgrano}}, formerly {{USS|Phoenix|CL-46|2}}, was sunk during the [[Falklands War]] in 1982.<ref name="e76">Ewing p. 76</ref>

The ''Brooklyn''-class ships had a strong influence on US cruiser design. Nearly all subsequent US cruisers, heavy and light, were directly or indirectly based on them.<ref name="e76"/> Notable among these are the {{sclass|Cleveland|light cruiser|2}} and {{sclass|Baltimore|heavy cruiser|2}} of World War II.
