Carrier Nonsense
All of this ignores the decreasing, rapidly decreasing, survivability of aircraft carriers. Within a procurement generation - 10 to 15 years - no carrier will have a combat life expectancy sufficient to justify its exposure to enemy contact/interdiction. What the Japanese did to the Prince of Wales and Repulse in 15 minutes in 1942 the Somalis will be able to do the Nimitz, Reagan etc in 2030 and God help the poor Queen Elizabeth.(I won't mention the name of her sister ship out of sensitivity to people's feelings) which will be sailing with none of the protection the US can give to its carriers.
The same could be said to apply to fast jets. Their development, build and deployment costs continue to outstretch the costs of killing them to the extent that purposeful affordability has almost disappeared.
So, how do we apply our technology in a way that is effective, durable and affordable?
We build or take up from trade, cheap general purpose ships, harden them a bit ("militarise" them) and use helicopters to launch and recover UAVs. As a refinement of launching we could use catapults in a similar way CAM merchantmen launched single use Hurricanes in WW2 leaving just recovery to helicopter capture.
In this way we can have lots of drones on lots of ships doing lots of different things all very cheaply and in an eminently scalable fashion in the event of conflict.
(Some fleeting Googling reveals a lot of weapon systems (examples I found include the Bushmaster and Goalkeeper systems) are already containerised and suited to deployment on temporary "warships",)
This is an affordable war fighting future where brains, imagination and adaptability (I know, not noted British qualities) and not money will rule.
