They have 2 carriers, I believe they are STOVL carriers though. And I think within a decade or 2 they will be down to 1. They are about to mothball some 200 naval vessels, so I dont know how much longer Britian will even be able to project force in the european theater let alone in far off lands.
They have 2 active light carriers,with one mothballed.The problem is that these have little real airdefence capability after having retired their SeaHarrier fleet.
