Preserving our History-Superstructure Preservation Project

Currently, work is being done to our superstructure and is expected to be completed by December 2017. For safety reasons, our flying and navigation bridges will be closed during restoration. We appreciate your patience and understanding and your part in helping to preserve America’s last Battleship
