They have a mock-up of a WWII Fleet Boat conning tower with three periscopes (OK - its not exactly a true mockup!!). Tristan checks out the views through the lower of the three. They don't move up and down, so they have them at three different heights for short, medium and tall people.
A view of Nautilus, taken through the periscope inside the Submarine Force Museum.
Jules Verne's Nautilus, hanging in the lobby at the museum.
Charlie and Tristan check out X-1, on display outside the museum.
The X-1 used to be on display at the Naval Academy in Annapolis, but they moved her to the Sub Force museum a few years ago.
A Japanese KAITEN submarine on display.
The sail from the GEORGE WASHINGTON is on display outside, along with a Polaris Missile (just barely visible above the sail).
