USS Des Moines (CA-134) was the lead ship of the class of United States Navy heavy cruisers. She was the first ship in the United States Navy to feature the auto loading Mark 16 8-inch/55 caliber gun, the first of its type in the world. She was the second ship of the US Navy to be commissioned with the name of the capital of Iowa. Launched 1946, she was commissioned in 1948. She saw duty around the world until her decommissioning in 1961; she was permanently mothballed. A 1981 survey was done to determine if she was worthy of reactivation for the 600-ship Navy, but the cost was too great so she remained in the reserve. She was struck off the naval reserve in 1993, which was followed by a campaign to turn her into a museum ship. The campaign failed, and in 2005 she was sold for scrapping, and she was broken up by July 7. Parts of the ship have been donated to various places for display, including at the USS Salem museum, which is the only Des Moines-class ship to avoid the scrapyard.
