The USS Des Moines (CA-134) was the lead ship of the Des Moines-class heavy cruisers built for the United States Navy, representing a significant advancement in naval artillery technology. Launched on September 27, 1946, by Bethlehem Steel's Fore River Shipyard in Quincy, Massachusetts, she was commissioned on November 16, 1948. The vessel was notable for being the first USN ship to be equipped with auto-loading 8-inch (203 mm) Mark 16 guns, the first large-caliber auto-loading guns in the world. Additionally, she was the first of her class to carry Sikorsky HO3S-1 utility helicopters, replacing traditional seaplanes, enhancing her operational versatility. Design-wise, USS Des Moines was a large, modern cruiser optimized for both gunfire support and fleet command roles. Her operational history was characterized by worldwide deployments during the early Cold War period. She frequently cruised from her home ports at Newport, Rhode Island, and later Norfolk, Virginia, engaging in exercises across the Caribbean, East Coast, North Atlantic, and Mediterranean. Between 1949 and 1957, she annually deployed to the Mediterranean, serving as flagship for the 6th Fleet, and participated in NATO exercises, port visits to Yugoslavia, and patrols during regional crises, such as the Suez Crisis of 1956 and the Lebanon crisis of 1958. Her active service emphasized projecting American power and supporting NATO operations, with notable visits to Yugoslavian ports and involvement in Mediterranean strategic activities. Her film footage was used in the 1959 movie "John Paul Jones," illustrating her presence in popular culture. Decommissioned in 1961, USS Des Moines was mothballed at the South Boston Naval Annex and later maintained in reserve at Philadelphia. A 1981 Congressional survey considered reactivation to support the 600-ship Navy but concluded that the costs were prohibitive, and she remained in reserve until struck in 1993. Attempts to preserve her as a museum failed, and she was sold for scrapping in 2005, dismantled by July 2007. Some parts, including her 5-inch gun mounts, were donated to the USS Lexington museum. Her legacy includes her technological innovations, service during the Cold War, and contributions to naval history.
