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.
Mothballed ships in Suisun Bay, California (2010). The battleship USS Iowa at the right-side end of the group has since become a restored museum ship in San Pedro, Los Angeles.
