USS Quincy, a 13,600-ton Baltimore class heavy cruiser, was built at Quincy, Massachusetts, and commissioned in December 1943. Following a Caribbean shakedown cruise and training in the North Atlantic, in May 1944 she reported to the 12th Fleet for service in European waters. During June 1944, Quincy provided gunfire support for the Normandy Invasion and bombarded German positions around Cherbourg, France. After steaming to the Mediterranean, the cruiser participated in the invasion of Southern France in August. She returned to the U.S. shortly thereafter.
In January and February 1945, Quincy transported President Franklin D. Roosevelt and his party most of the way to and from the Yalta Conference. When the conference was completed, she was the site of meetings between the President, King Farouk of Egypt, Emperor Haile Selassie of Ethopia and King Ibn Saud of Saudi Arabia. Upon her arrival back in the United States, Quincy was transferred to the Pacific, where she escorted the fast carriers as they conducted air strikes on targets in the Ryukyus and the Japanese Home Islands during the last five months of World War II. In mid-July, she used her own eight-inch guns to bombard an iron plant at Kamaishi, Japan. After Japan's capitulation in August, Quincy supported occupation efforts.
Quincy was decommissioned at Bremerton, Washington, in October 1946. However, the coming of the Korean War brought a need for more active gun ships and Quincy was recommissioned in January 1952. She made one Western Pacific deployment, arriving in July 1953, just as the conflict was negotiated to an end, and remained in Asiatic waters until December. She was again decommissioned in July 1954 and spent nearly two decades in "mothballs" at Bremerton. USS Quincy was stricken from the Naval Vessel Register in October 1973 and sold for scrapping in August 1974.
