I would generally concur on the overall flow of things here... even if the RN kept the centaurs conventional eventually Albion and Bulwark go the commando route. I had not thought about new carriers being possibleAlthough the Sverdlov cruisers alarmed the RN sufficiently for it to develop Buccaneer and get it into service on Victorious, Hermes, Eagle and Ark (Green Cheese was not so lucky) the main work of RN carriers in general war was seen as being ASW.
The focus was on getting whatever could be got into service.
Reinforcing Singapore and providing fighter cover with their Tigers would have been the main impetus for using Bulwark and Albion as well as Centaur and Hermes as fixed wing carriers. With Victorious, Eagle and Ark they would have worked hard up until 1966 East of Suez.
After 1966 the focus has to shift to NATO for both political and budgetary reasons. But Eagle and Hermes could have survived with their Tigers into the 70s with Centaur and Bulwark taking over from Ocean and Theseus as Commando ships.
The AFVG/Mirage M is selected to replace the Tigers in 1970. The incoming Conservative government orders the Hermes sized anglo french carrier (PACV70) to enter service from 1979. The RN gets Queen Elizabeth and Eagle (Prince of Wales is renamed Eagle after the latter became the star of the BBCTV doc "Sailor" and is adopted by HM theQueen Mother). France gets Charles De Gaulle and Richelieu.
Queen Elizabeth and Hermes sail for the Falklands in 1982. QE has the new Tornado/Mirage M fighter/attacker while Hermes operates Tigers and Bucs. Hermes and her airgroup had been sold to Australia as HMS Australia. Canberra agrees to let the RN keep her for the duration. But Eagle is completed at breakneck speed. Hermes returns to Portsmouth in the Summer to be refurbished for the RAN with her Tigers and Bucs. The Tiger has had its second combat moment with the RN (the first was in the F East in 1963 against Indonesian Migs and Badgers)
