Your first point would appear to contradict the last point there, can you divulge?
The carrier(s) we currently have are HMS Illustrious and HMS Ocean, although Ocean wasn't designed for and never has operated fixed wing aircraft. HMS Ark Royal was retired at the same time we scrapped the RAF Harriers (2010-2011). HMS Invincible was retired in 2005 - at the same time as the RN lost it's Sea Harriers.
All of these carriers are small - less than one quater the size of Nimitz. If you're going to operate anything (fixed wing) off them it needs to be VSTOL (aka Jump Jet) - so basically Harrier. But we've scrapped/sold all our Harriers.
Loss of the Harriers has left us without any fixed wing stuff to operate from our ships. Many blame this on a struggle between the RN and RAF. The RAF want to operate ALL fixed wing jets, and don't want to embark on ships if they can help it. The RAF Harrier - the GR5/7/9 was becoming a very capable ground attack/support aircraft, but couldn't perform air defence because it didn't have a radar, and wasn't capable of carrying the latest air to air missiles. The Sea Harrier had a very good radar, and could launch all the latest air-to air missiles but it was an old underpowered design in need of replacement.
So - 2004/5 stage one of the RAF coup was to get MOD to 'suggest' to HMG that the Sea Harriers are retired, and the RN convert to the RAF version - the GR7 - thus saving money. RN squadrons would be allocated a portaloo and a (half a) tent at the RAF base in Rutland, and move up there (from sunny Somerset) to fly the RAF GR7's. For reasons no-one really understands, the Admiralty didn't object, and HMG then proceeded to scrap the Sea Harrier fleet, and retire the oldest carrier - HMS Invincible. Twelve new Type 45 destroyers could be used to defend the fleet from air attack.
Stage 2 - 2007-20010 embark on an upgrade of the GR7's to GR9 standard. Although this didn't involve adding an air-to-air radar it did add considerably to the capabilities of the aircraft. These were supposed to stay in service till 2018 when the new carriers, and the new F-35 Joint strike fighters would be introduced to replace them. Stage 3 - The smelly stuff hits the air conditioning, and HMG is skint. Savings have to be made. The choice at the RAF is to either half the Tornado GR4 fleet from 120 aircraft to 46 and keep the Harriers, or to scrap the Harriers, and keep all 120 off Tornados. An ex Tornado guy is in charge at the MOD. The decision is made to scrap the Harriers. And the order for Type 45's is reduced to 8 ships.
Stage 4 - The hysterical laughing from the RAF side of the MOD cause the RN/Admiralty to wake from their (rum induced?) coma and realise they have 2/3 aircraft carriers, and no aircraft fo operate from them. Even if the F35/JSF were to arrive on time, there was going to be a gap of 8-10 years without any aircraft. So scrap another carrier, convert the remaining ones for helicopter only ops, and hope no-one notices. And the order for Type 45's is reduced to 6 ships.
'Kin' idiots - the lot of them.
