The Worcester class was designed as a departure from the Cleveland-class and Fargo-class cruisers, and an expansion of the Atlanta and Juneau classes.[dubious – discuss] They carried six twin dual-purpose 6-inch/47-caliber gun turrets on the center-line, of which turrets three and four were superimposed. They carried 24 3"/50 cal AA in eleven twin mounts and two single mounts. Fire-control equipment included four high-angle/low-angle director control towers (DCTs) and two low-angle DCTs, which were arranged in a diamond-shaped pattern. Their armor was a 3–6" belt, a 3" main deck, a 2" lower deck, 3–4" bulkheads, 4" turrets and barbettes, and a 6.5" conning tower. Four Babcock & Wilcox boilers with four shafts and General Electric geared turbines provided 120,000 S.H.P., which could propel these ships at 32.75 knots.1
