USS Norton Sound (AV-11/AVM-1) was originally built as a Currituck-class seaplane tender by Los Angeles Shipbuilding and Dry Dock Company, San Pedro, California. She was named for Norton Sound, a large inlet in West Alaska, between the Seward Peninsula and the mouths of the Yukon, north-east of the Bering Sea.

The Currituck-class seaplane tenders were four ships built for the United States Navy during World War II. The role of a seaplane tender was to provide base facilities for squadrons of seaplanes in a similar way that an aircraft carrier does for its squadrons. While three members of the class were removed from active service in the 1960s, Norton Sound was modified to serve as a testbed for advanced radar and combat management systems, such as the Aegis Combat System.
