Sadly she is well past her sell by date but apart from not being able to man\woman that ship, would we have enough aircraft to take advantage of such a mean machine...
We did exercises with that goliath way back in the early 1960's and here she is finally decommissioning, it has certainly been around the block once or twice.
Would it fit into our dockyards and is there a dry dock big enough to cater for this size aircraft carrier?
