Just remind me how many aircraft have tried to attack the uk since WW2 in daylight let alone in bad weather at night?
And please don't give me the "thats because we have Tornado/typhoon" crap.
By that argument people who wear tinfoil helmets to keep out the mindwaves have been sucessfull too.
There has been no credible AD threat for a very long time against mainland UK.
Carriers, however, are always useful from war to sabre rattling to humanitarian.
