A modern Royal Navy in World War II: capability and ammunition limits

If the modern Royal Navy replaced its World War II counterpart, could it end the war before exhausting its ammunition?

Ammunition and fleet numbers are expected to run short, despite the advantages of nuclear submarines and F-35s. Arrival in 1939 against Germany alone is treated more favourably, while nuclear use is raised as a separate and uncertain possibility.

The hypothetical modern fleet has enormous advantages in individual weapons and platforms. Nuclear-powered submarines would be effective, but their available torpedoes would not cover every required target. Cruise-missile stocks and the number of ships available for simultaneous commitments also constrain the campaign. Queen Elizabeth-class carriers with F-35s are considered overwhelmingly superior to anything Germany could oppose in 1939. That starting point offers a more favourable scenario than meeting the whole war's later demands. Nuclear weapons are raised as a way to avoid the conventional-ammunition shortage, with uncertainty over whether Churchill would use them.
