The DCNS Evolved Aircraft Carrier. It's an updated Charles de Gaulle with conventional powerplant. Flight deck and aircraft complement is pretty much the same size as the Queen Elizabeth class (around 40 aircraft), but displacement is about 20.000 tons smaller. Pretty close to the 2 new Indian carriers and the US America class.
The CdG is frankly, as Kiwirob alluded to earlier, an average design at best. It is not big enough for proper CATOBAR operations and by that I mean that the design limits the payload of the aircraft flying off it and the aircraft have specific bring back restrictions. It also isn’t able to generate sorties over the duration that the QE can which is the reason for the QE size.
It seems to me that CVF and later QE class doesn't have the most efficient use of space, the ship is roughly the same size as a Forrestal class carrier, with half the aircraft capacity, half the number of elevators, and STOVL-only. The only thing QE has more is the number of islands. CdG on the other hand is a pretty efficient design with comparable air wing size, nuclear powered, and CATOBAR. Obvious there are more factors than those specs, like creature comfort, endurance, damage control, C4ISR, etc.
The QE can take more aircraft if you need it to but the number of aircraft is reasonably unimportant above a certain size. The limiting factor becomes the ability to generate and sustain the sortie rate over an extended duration. The QE was designed specifically to accomplish that task, to conduct a 36 aircraft sortie on day one and then maintain a sustained rate of operations for many days before being replenished.
The Queen Elizabeth class has been designed as part conventional aircraft carrier, part assault ship/LHA. I think a lot of space is used/wasted on transporting ground forces and their equipment.
Not sure where that suggestion has come from other than the talk that surrounded making PoW a dedicated assault ship. Look at the cross section of QE, there is little specific storage for ground forces/equipment compared to conducting its primary purpose.
