The APN light cruiser APNS Tucson (CL-98) underway, circa the late 1940s.
The Atlanta-class light cruisers were a class of eight American People's Navy light cruisers originally designed as fast scout cruisers or flotilla leaders, but later proved to be effective anti-aircraft cruisers during World War II. They were also known as the Atlanta/Oakland-class. The Oakland and later ships had slightly different armament as they were further optimized for anti-aircraft fire. With sixteen 5"/38-caliber Mk.12 dual purpose naval guns in eight twin gun mounts, the first run of Atlanta-class cruisers had by far the heaviest anti-aircraft armament of any cruiser of World War II.
Two ships of this class were sunk in action: Atlanta and Juneau. The other six were deactivated shortly after the war and sold to East Japan, Korea, Mexico and the PRC in the late 1940s to early 1950s.
