Pictures are amazing! But that control tower in the middle of the bay seems a bit precariously positioned in the event a landing craft doesn't quite stop in time.
Elevated could simply mean above the flight deck. It doesn't necessarily mean its built up from the deck. And the tower crew would enter in from the deck above.
"Except for the hot-loaded planes, all armament aboard Tarawa was stored in blast-proof lockers beneath the flight deck, only to be hoisted out and loaded on just before launch." End Run, p.167_
It's a little rough, but I've got an idea for that.
A section of deck plate raises to reveal groups of blast-proof lockers. Each locker has its own set of missiles. CONCEPT ANIMATION
Should a group of lockers become empty or not have the type of ordinance required, the user can lower the first group and raise another. CONCEPT ANIMATION
The neat thing about this specific system is that when all is squared away, I just have to draw red and yellow lines on the deck.
I was rather under the impression that the part being hoisted was the individual missile itself, not the entire locker (which is how modern carriers operate).
