An obsolete battleship isn't something that's very useful; they take up a lot of room. So it's not surprising that there are not many of these old ships around.
I'll be first looking at the Battleship Texas, which is in Houston, and then the Battleship Alabama, which is in Mobile. You'd be right thinking that the only reason these two ships were saved from being scrapped was the fortune of their name. The states for which each was named successfully convinced the Navy that they'd take them.
Let's compare:
The Texas served in both world wars and shows the ability of the naval engineers to keep her relevant well beyond what could realistically have been expected when she was launched.
The Alabama represents several generations of development, and save for the next generation of Iowa Class battleships that came soon after, the Alabama is as good as they ever were.
Battleship Texas State Historic Site
The Texas has had a rough life and it's remarkable that she looks as good as she does. Even so, a great deal of work and money will be required to keep the whole ship in a good state of repair and to stop the decay. The plan is to eventually display this ship in a permanent dry-dock to eliminate further rot of the hull.
Few ships look as menacing as those old Dreadnaught ships with their reverse-angle bows.
Those who served onboard the Texas didn't have an easy job getting from once place on the ship to another. The ship was not designed for their comfort.
A look into one of the big turrets (you enter from below).
Guided tours are offered, where some of the more remote areas can be seen. But, even the standard self-guided tour is quite good, and much of the ship is open.
A battleship holds many men and it has to supply everything they'll be needing.
There are only twelve small rooms for officers--everybody else is well-crowded together. When the ship was built, hammocks were the norm. By the second world war, these drop-down beds had replaced most of those.
USS Alabama Battleship Memorial Park
While the Texas looked every bit its age (over a hundred years old), the Alabama seems to be in pretty good shape.
There's no lacking for guns.
This turret for the 16" guns is vastly more complex than what is seen on the Texas.
There is a good museum on the main deck.
Engine control.
Ammunition is seemingly stored everywhere (within the protected areas of the ship).
The analogue computers that control the guns. This is very sophisticated. The guns are fired from here--the crew up top is needed to load the shells
Feeding the crew could not have been straightforward--there are so many of them and so little space.
