one was commissioned in '85. they're both stovl carriers, which is nothing compared to our supercarriers. they are limited to harrier type aircraft.
we have harriers, they can be used on amphibious ships, which is why the marines have them. harriers can land/take off pretty much anywhere a chopper can. those give us that many more available planes.
then there are our bases like diego garcia-a dot in the middle of the ocean, in the middle of nowhere. for fueling purposes for our bombers, etc.

and the harriers that the brits and others use-they're good, which is why we have them. but not as good as our other planes.
it's why afganistan annoys me to no end. people look at that and say wow, the us can be defeated. not in a conventional war we can't.
