'The idea of flying complicated, heavy manned aircraft off of a huge, complex, vulnerable floating platform was great before radar and guided missiles. These days carriers are like battleships in the second world war - hugely impressive, but not really of very much use.'
The USN had more aircraft over Afghanistan than the RAF had in it every day of the conflict, so I'd say they're pretty handy. Especially if you don't want to live in Afghanistan for six months.
