The USS Quincy (CA-71) was a Baltimore-class heavy cruiser built for the United States Navy during World War II. Laid down at the Fore River Shipyard of Bethlehem Steel in Quincy, Massachusetts, on 9 October 1941, she was initially named St. Paul but was renamed Quincy on 16 October 1942 to honor the previous USS Quincy, which was lost at the Battle of Savo Island. Launched on 23 June 1943 and commissioned on 15 December 1943 under Captain Elliot M. Senn, she measured approximately 610 feet in length with a beam of about 66 feet and displaced around 13,600 tons standard. Her armament included Bofors 40 mm guns, which she notably retained longer than other ships of her class. Quincy's active service began with training and deployment in European waters, where she participated in shore bombardments supporting the Normandy invasion on D-Day, June 6, 1944. She provided precise naval gunfire against enemy batteries, supporting Allied landings at Utah Beach and the subsequent Battle of Cherbourg. Following operations in the European theater, she moved to the Mediterranean, conducting bombardments in Palermo, Sicily, and supporting the landings on southern France at Baie de Cavalaire in August 1944. After returning to the U.S. for repairs and upgrades, Quincy embarked on a notable diplomatic cruise in early 1945, carrying President Franklin D. Roosevelt during the Yalta Conference and other meetings with Allied leaders. She then joined the Pacific Fleet, supporting carrier strikes against Okinawa and Japan’s mainland. During her Pacific service, she engaged Japanese aircraft, supported major carrier operations, and participated in the occupation of Japan, entering Tokyo Bay in September 1945. Decommissioned in October 1946, Quincy was later recommissioned during the Korean War era, serving support roles off Korea in 1953–1954. She was finally stricken from the naval register in 1973 and sold for dismantling in 1974. Her legacy includes her involvement in major WWII operations, her role in diplomatic history, and her preserved ship’s bell displayed in Quincy, Massachusetts.
