The aircraft was chosen before the ship speed (let alone the machinery fit) was finalised. There will be enough grunt in the combined ship speed plus cat to get an F35C aboard with the required bring-back. It's Dave B that's having issues, hence the extremely safe, operationally feasible and in no way desperate Rolling Vertical Landing......
Would personally have put more grunt into the ship, but with a twin-screw, you're loading the props fairly heavily anyway. Any potential Foos looking at QE/PoW should be aware that their cabins are largely well away from the flightdeck and tie-down points. Unfortunately, their cabins are separated from two of the most highly loaded props in the world by some nice large water ballast tanks...........
