Bearing in mind todays belated press copy about RN ship strength, I remain convinced that the push for the big carriers was simply a budget grab by MOD. They were unable to make the case for the RN that the UK of today needs and so, have gone for huge bling and all the eggs in one basket (two actually) in the blind hope that the real need for other ships will become imperative and eventually be partly addressed.
One thing about the vulnerability of these big ships is that if they are ever employed against a country that really requires the use of their hi-tech conventional weaponry, they become perfect targets for tactical-use of nuclear weapons against them.
Just my opinion.
