The Atlanta-class cruisers were eight United States Navy light cruisers which were designed as fast scout cruisers or flotilla leaders but which proved to be effective anti-aircraft cruisers during World War II. They were also known as the Atlanta-Oakland class. The Atlanta class originally had 16 x 5-inch (127 mm)/38 caliber guns in eight two-gun turrets, arranged with three superfiring turrets forward, three more superfiring aft and two waist mounts, one port and one starboard, giving the first four Atlanta-class cruisers the heaviest anti-aircraft armament of any cruiser of World War II. The last four ships of the class, starting with Oakland, had a slightly revised armament with a reduced main gun battery - the waist turrets being deleted - as they were further optimized for anti-aircraft fire in light of war experience.

She played a minor role in World War II after escaping from Greece during the German invasion in early 1941. Influenced by communist agitators, her crew mutinied in 1944, but it was suppressed without any bloodshed. Georgios Averof returned to Greece after the German evacuation in late 1944 and became a museum ship in 1952. She is the only surviving armored cruiser in the world.
