Perhaps I could add something here...
'anywhere on the planet' - well, it's true a carrier can't get to the centre of large land masses. But their ability to get to some bits of land has been useful in the past. Just can't think of any right now...
Oh, yes - those places in the Pacific in WW2
Oh, and Korea when there weren't any land bases
Oh, and Suez
And the Falklands....
Sierra Leone, Beira, Indonesia, etc., etc.
Honestly, folks, no-one is suggesting that carrier borne aviation can do everything. I've not heard anyone suggest naval aviation as a replacement for all land based aviation. But, honestly, there does seem to be a little traffic going the other way. Could we not agree that having two large carriers is a really, really, really significant and flexible capability and then work out how best to use them to the max?
Best regards as ever to all those working out how to use them to the max,
