Cleveland-class cruiser

A development of the preceding , the Cleveland class was designed with increased cruising range, anti-aircraft armament, and torpedo protection compared with earlier U.S. cruisers. After the London Naval Treaty of 1930, the U.S. Navy took up a renewed interest in the 6-inch gun-armed light cruiser, partially due to the Navy complaining about the 8-inch gun's slow rate of fire of three rounds per minute compared to the ten rounds per minute of 6-inch guns. At this time, the U.S. Navy began to deploy drones to use as targets for anti-aircraft targets, which could simulate both dive and torpedo bombers. The simulations showed that without fire control directors and computers, the ships of the fleet would be almost helpless against the density of aircraft attacks envisioned in any future war. Mechanical computers alone could weigh up to 10 tons and had to be housed below decks for both weight and protection measures. As World War II was to prove, the pre-war assumptions were optimistic as eventually, every anti-aircraft gun platform above 20 mm would end up having remote power, with fire control and radar aiming. As designed, the Cleveland class was already a tight design, but requests to widen the ship were turned down as it would affect production rates. Top weight issues would plague the class with every addition of equipment having to be weighed against what would have to be removed. For example, the tighter installation of the control radar necessitated the removal of the 20 mm clipping rooms, where 20 mm rounds were loaded into their magazines. ==Service==

The Cleveland-class cruisers served mainly in the Pacific Fleet during World War II, especially with the Fast Carrier Task Force, and some served off the coasts of Europe and Africa in the U.S. Atlantic Fleet. All of these warships, though worked heavily, survived the war. All were initially decommissioned by 1950, except for , which remained in service until 1956. None were recommissioned for the Korean War, as they required a crew almost as large as the ships, so those were reactivated instead. All non-converted ships were sold off from the reserve fleet for scrapping beginning in 1959. The six that were completed as or converted into guided missile cruisers were reactivated during the 1950s and then served into the 1970s. All, particularly the Talos-armed ships, suffered from greater stability problems than the original design due to the extra top weight. This was particularly severe in Galveston, leading to its premature decommissioning in 1970. and had to have a large amount of ballast and internal rearrangement to allow service into the 1970s. The last of these missile ships in service, Oklahoma City, was decommissioned in December 1979. Museum ship One Cleveland-class ship remains. , refit in 1960 and re-designated as Galveston-class guided missile light cruiser CLG-4 (later CG-4), is now a museum ship at the Buffalo and Erie County Naval & Military Park in Buffalo, New York, alongside the , and the , . ==Ships in class==
