Don't you think that hangar is extremely overcrowded ? There is no place to even move fighter to elevator.
i think he just used that drawing to show that there are place for that many, but I think he will have some of the fighters that are ready on deck as many other aircraft carrier have.
For all that, the elevator disposition is extremely poor. Most of the enclosed volume would be very inaccessible in any but the most ideal case, and a single fire could ravage the entire hangar deck and leave no square foot of it untouched.
