US and British carrier doctrine were built for different fleets

What is the difference between US and UK carrier doctrine?

The US can fund specialised carrier and amphibious fleets, while Britain sought a smaller interoperable force whose flight decks could shift between strike and lift roles.

Comparing the Queen Elizabeth class directly with US carrier doctrine misses the original British plan for a mixed carrier and LHD force. Common aircraft could shift among several flight decks, with some ships optimised for strike and others for amphibious lift. That flexibility is a medium-power answer to limited numbers, whereas the US Navy can sustain multiple specialised carrier and LHD fleets.
