Baltimore's Maritime Museum, located in the Inner Harbor, is made up of three historic ships and a lighthouse, all of which are National Historic Landmarks. The collection consists of the USS Torsk, a Tench Class fleet-type submarine that saw action in the Second World War, US Coast Guard Cutter Taney, an amphibious command ship during the Battle of Okinawa, Lightship Chesapeake (essentially a floating lighthouse) and Seven Foot Knoll Lighthouse.
