Description
Derived from the heavy cruisers, they were larger, had an improved machinery layout, and carried a new design of auto-loading, rapid-fire 8"/55 gun (the Mk16). The improved Mk16 guns of the main battery were the first auto-loading 8" guns fielded by the US Navy, and allowed a much higher rate of fire than earlier designs, capable of sustaining seven shots per minute per barrel, or about twice that of the Mk12s found on the Baltimore class. The auto-loading mechanism could function at any elevation, giving even these large-caliber guns some anti-aircraft ability. While the secondary battery of six twin 5"/38 Mk12 DP guns was essentially unchanged from the preceding and Baltimore class cruisers, the Des Moines class carried a stronger battery of small-caliber anti-aircraft guns, including 12 twin 3-inch/50 Mk27 and later Mk33 guns, superior to the earlier ships' quad-mounted 40mm Bofors.History
Three ships of the class were completed: , , and . The first two were decommissioned in 1959 and 1961, respectively, but Newport News remained in commission until 1975, having the distinction of being the last active all-gun cruiser and the first completely air-conditioned surface ship in the U.S. Navy.
