Atlantic Reserve Fleet, Norfolk was a part of the United States Navy reserve fleets, also called a mothball fleet, and was used to store the many surplus ships after World War II. The Atlantic Reserve Fleet was just south of the Norfolk Naval Shipyard, called the South Gate Annex in Portsmouth, Virginia, 2 mi (3.2 km) south of Norfolk, Virginia. The reserve fleet was stored in the freshwater of the Elizabeth River, Southern Branch near the Jordan Bridge. The freshwater was good for long-term storage for ships. Some ships in the fleet were reactivated for the Korean War and Vietnam War.

The United States Navy maintains a number of its ships as part of a reserve fleet, often called the "Mothball Fleet". While the details of the maintenance activity have changed several times, the basics are constant: keep the ships afloat and sufficiently working as to be reactivated quickly in an emergency.
