There’s carriers and there’s carriers. Catapult and wire (CATOBAR) carriers are only fielded by the US, France and bizarrely Brazil, everyone else uses some sort of Short Take Off arrangement with a ramp and arrestir wires or vertical landing,
Our carriers, are basically big helicopter carriers and can’t field mini-AWACS aircraft, so will have to make do with altitude limited Merlin choppers with a bolt on radar. We can’t launch Hawkeye type aircraft which severely limits the range that our ships can detect incoming missiles or hostile aircraft.
The F35B is very expensive, can’t carry much and isn’t a dog fighter. We should have bought off the shelf catapults, traps, Hawkeyes and Rafales/F-18Es.
They’re a typical British lash-up, an expensive one at that.
