The successor to that one is the USS Trayer. It's at Great Lakes Naval Training Center. It's a 2/3 scale Navy destroyer, indoors, in a water tank alongside a pier. It's not just a mockup; it's a large-scale simulator, and most of the equipment works. New Navy recruits go through a 12-hour training exercise on the ship, called "Battle Stations 21". The Navy doesn't give out full details, but fire and flooding are involved.

It is shorter bow to stern. Rooms are normal vertically.
