The unbuilt CL-154 design appears as a late-war answer to limitations exposed by the Atlanta class. Its proposed battery included as many as eight twin 5-inch/54 mounts and eight twin 3-inch/70 mounts. At roughly 12,000 tons, it was substantially larger than the wartime Atlantas. The proposal depended on newer weapons and a displacement that the earlier ships did not have. Its combination of armament and size placed it closer to the desired AA and screening cruiser in this comparison.

CL-154 pushed the screening cruiser much further
A September 1945 U.S. design paired 5-inch/54 and 3-inch/70 batteries on a roughly 12,000-ton hull, showing how far the concept had moved beyond Atlanta.
