USS Manchester was a light cruiser of the United States Navy, which were built during World War II. The class was designed as a development of the earlier s, the size of which had been limited by the First London Naval Treaty. The start of the war led to the dissolution of the treaty system, but the dramatic need for new vessels precluded a new design, so the Clevelands used the same hull as their predecessors, but were significantly heavier. The Clevelands carried a main battery of twelve guns in four three-gun turrets, along with a secondary armament of twelve 5"/38 caliber gun| dual-purpose guns. They had a top speed of .

The ship was laid down 25 September 1944 by the Bethlehem Shipbuilding Corporation's Fore River Shipyard, Quincy, Massachusetts; launched 5 March 1946; sponsored by Mrs. Ernest J. Gladu; and commissioned 29 October 1946, Capt. Peter G. Hale in command.

Design

The Cleveland-class light cruisers traced their origin to design work done in the late 1930s; at the time, light cruiser displacement was limited to by the Second London Naval Treaty. Following the start of World War II in September 1939, Britain announced it would suspend the treaty for the duration of the conflict, a decision the US Navy quickly followed. Though still neutral, the United States recognized that war was likely and the urgent need for additional ships ruled out an entirely new design, so the Clevelands were a close development of the earlier s, the chief difference being the substitution of a two-gun dual-purpose gun mount for one of the main battery gun turrets.

Manchester was long overall and had a beam of and a draft of . Her standard displacement amounted to and increased to at full load. The ship was powered by four General Electric steam turbines, each driving one propeller shaft, using steam provided by four oil-fired Babcock & Wilcox boilers. Rated at , the turbines were intended to give a top speed of . Her crew numbered 1285 officers and enlisted men.

The ship was armed with a main battery of twelve 6 in /47-caliber Mark 16 guns in four 3-gun turrets on the centerline. Two were placed forward in a superfiring pair; the other two turrets were placed aft of the superstructure in another superfiring pair. The secondary battery consisted of twelve /38-caliber dual-purpose guns mounted in twin turrets. Two of these were placed on the centerline, one directly behind the forward main turrets and the other just forward of the aft turrets. Two more were placed abreast of the conning tower and the other pair on either side of the aft superstructure. Anti-aircraft defense consisted of twenty-eight Bofors guns in four quadruple and six double mounts and ten Oerlikon guns in single mounts.

The ship's belt armor ranged in thickness from , with the thicker section amidships where it protected the ammunition magazines and propulsion machinery spaces. Her deck armor was thick. The main battery turrets were protected with faces and sides and tops, and they were supported by barbettes 6 inches thick. Manchesters conning tower had 5-inch sides.

Manchester completed her shakedown cruise in the Caribbean and returned to Boston, her home port, 26 March 1947. There she was equipped with an experimental plastic cover for her bridge to be tested on her first transatlantic crossing. On 18 April, she steamed for the Mediterranean to lend visible support to the Truman Doctrine of 12 March. Returning to the East Coast for two weeks in June, she conducted a Naval Reserve training cruise out of Newport, R.I. She resumed her Mediterranean cruise 25 June, returning to Boston 30 November. Manchester completed two more deployments with the 6th Fleet (9 February to 26 June 1948, 3 January to 4 March 1949) before departing Philadelphia 18 March for assignment with the Pacific Fleet. who would later be the Director of the National Security Agency under Presidents Eisenhower and Kennedy.
