Philadelphia is home to a major US Naval shipyard, and several museum ships, Cruiser USS Olympia, Submarine USS Becuna, and across the river in Camden NJ, the Battleship New Jersey. The Olympia is of special note given that it it is the only surviving US warship of the Spanish American War, during which she was the flagship of Commodore Dewey in the battle of Manila Bay. The Becuna is a WW2 era submarine, and the New Jersey, a WW2 Iowa class battleship.
