What are those two longitudinal, narrow black squares, just forward of the deflectors?
could that position be sensible for weapons elevators?
If so, it could also tell us how long the hangar is, as it's unlikely hangar would go farther than that.
Certainly not impossible -- having a weapons elevator between the two forward catapults is something seen on the Nimitz class as well (among other locations).
I believe we can already see the most topside flight deck module in the staging area, corresponding to the weapons elevators as well, alongside the starboard catapult track (yellow)
