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.
Suisun Bay is a shallow tidal estuary in Northern California. It lies at the confluence of the Sacramento River and San Joaquin River, forming the entrance to the Sacramento–San Joaquin River Delta, an inverted river delta. To the west, Suisun Bay is drained by the Carquinez Strait, which connects to San Pablo Bay, a northern extension of San Francisco Bay. Grizzly Bay forms a northern extension of Suisun Bay. Suisun Bay is between Contra Costa County to the south and Solano County to the north.
The National Defense Reserve Fleet (NDRF) consists of ships of the United States, mostly merchant vessels, that have been mothballed but can be activated within 20 to 120 days to provide shipping during national military emergencies, or non-military emergencies such as commercial shipping crises.
A Naval Inactive Ship Maintenance Facility (NISMF) is a facility owned by the United States Navy as a holding facility for decommissioned naval vessels, pending determination of their final fate. All ships in these facilities are inactive, but some are still on the Naval Vessel Register (NVR), while others have been struck from the register.
The Beaumont Reserve Fleet, was established by act of Congress in 1946, as a component of the National Defense Reserve Fleet (NDRF). The fleet is located in Beaumont, Texas.

USS Soubarissen (AO-93) was an Escambia-class fleet oiler converted to a water tanker, named for a chief of the "Neutral" Indian Nations which, although a part of the Iroquois confederation, were called "neutral" by the French because they took no part in the wars of the Iroquois and Hurons. The area he governed included the oil fields of northwestern Pennsylvania and western New York. The knowledge of the oil seepages there was well known among the Indians, and it was declared neutral ground so all Indians could obtain oil for medicinal and domestic purposes without danger or interference. In 1627, Joseph de La Roche Daillon heard of the oil springs and made an expedition to visit them. He was kindly received by Chief Soubarissen, shown the oil seepages, and duly reported his observations to his superiors. These observations contributed largely to the interest in the petroleum resources of the Pennsylvania region.

At the end of the war in November 1945 the shipyard was closed and the base was turned into the Texas Group, Atlantic Reserve Fleet with 250 ships.
The James River Reserve Fleet (JRRF) is located on the James River in the U.S. state of Virginia at near Fort Eustis. James River Reserve Fleet, a "ghost fleet", is part of the National Defense Reserve Fleet. The Reserve Fleet ships in storage, called "mothballed", that can be ready for use if needed. Many are awaiting scrapping due to the age or condition of the ship. Some ships are used for target practice or as artificial reefs. A few ships became museum ships and other sold to private companies. Ships can be readied for use in 20 to 120 days during national emergencies or natural disaster. The U.S. Department of Transportation's Maritime Administration (MARAD) provides oversight of the James River Reserve Fleet. For the United States Navy ships the United States Navy reserve fleets stored these ships and submarines.
