Yes maybe so but on paper she can carry a lot more than old Victorious.
Normally she'll carry up to 40 F-35s and a squadron of Merlin AS helicopters but as I've just read she has the designed capability to be overloaded with 70 F-35s, 250 Marines, Chinooks, Wildcats, and Apache attack helicopters. So that needs to be taken into account for the space, storage of parts and GSE, the accommodation of the 250 Marines, all that must add up. Plus like all new vessels she has that extra capacity to have the midlife upgrade so they have inbuilt space for the new equipment.
