Well maybe not, but there's a lot of space and a lot of holes in the Tempest design, including the fact that the Bridge is physically disconnected from the main 'body' of the thing, ergo, it's flimsy, which is not something you want to see in any sort of ship, especially not a warship.
No, it carries the same number of Interceptors which means it needs to be the same size, especially as it wastes so much more space on openings than the old Carrier did.
Gameplay >> everything else, they actually need to have the Interceptors to hand to be able to use them, which means that unless they're right in the middle of a safe-zone they need to keep all the Carriers equipped with Interceptors anyway.Moreover, the economic benefit comes from this: Let's say the Protoss have 100 Carriers in their fleets across the galaxy and each Carrier is set to be outfitted with 1,000 Interceptors. They'd need 100,000 Interceptors to support them all. By centralizing Interceptor storage, this number can be significantly lowered since the odds that all Carriers would be engaged in combat at all locations at the exact same time is highly unlikely. Moreover, losing a Carrier would not lead to the loss of those 1,000 Interceptors. Again, this conserves resources.
And any saving on Interceptors are taken up by materials wasted on the Tempest design.So, even if their size remain the same, it doesn't matter since the savings come from other aspects.
Take a look again, the Mutalisks fly through the sides 'where the Interceptors come out', so, no, they don't even touch the hull.Seriously, I keep seeing people complain that the new Carrier looks flimsy, etc. If you look at the old Carrier carefully, it's pretty flimsy as well! The entire hull is largely hollow and can lore-wise be blasted through by a Mutalisk (as evidenced in the original Protoss ending).
It was closer to half actually, and remember that this was meant to run on low-end computers, so there can't be too many details. Also, the only time we might see the interceptor bays is on the final approach, and we see that head on, so we don't get to see most of the inside of hollow section anyway.Also, the old Carrier also isn't sensibly able to carry all those Interceptors either. In the video I linked, the Mutalisk enters the Carrier. When they show the inside, the hollowed-out front 2/3 mostly contain scaffoldings. There was no sign of any Interceptors or docking bays of any sort.
