The other thing is any half decent air force with half decent modern planes would have run rings round them. Harriers were often escorted and used in a ground attack role. Brilliant aircraft but subsonic, rather short range however they had a fairly decent payload (nowhere near the F35B though). Questions would also have to be asked if they would have been capable of defending the carrier against faster more agile aircraft. Especially now that relatively cheap, fast, well armed drones are becoming common place.
Obviously not a problem in Iraq or afghanistan.
If Argentina, and their SA allies including Brazil which has an aircraft carrier, invade the Falklands before 2020 there isnt a thing we can do about it.
