A couple of the 5"/38cal. twin mounts. They could be used for anti-aircraft defense or shore bombardment. This gun was the same as the main gun on a Destroyer of that era. Destroyers usually had five. Alabama has twenty.
Inside of one of the 5" mounts. Tight in there for sure.
Spare 40mm AA gun barrels stored below decks against one of the main gun barbettes.
They cut an access portal into one of the barbettes so people could see what it was like inside. Back in the day, the only way into or out of this space was down through the turret. It was done like that to keep fires and explosions contained.
16" shells. A lot of them.
One compartment is a memorial to Senator Jeremiah Denton, Retired Admiral, naval aviator, ex-POW and all-around great American.
mentioned on this blog before. And I have his book. It was an honor to be in his space aboard Alabama.
