Nurse - given weather and a sea state which would allow unhindered launch and recovery of naval Buccaneers and F4s, there's no doubt that Stanley aerodrome would soon have been put out of action; the Mirages and Daggers would have stood little chance against front hemisphere AIM7s launched by naval F4s. There would have been no real need for the Black Bucks - and Gannets would have provided organic fleet AEW.
But we only had our little Harrier carriers which lacked significant punch and whose SHARs were predominantly used as 'eyeball' fighters which only succeeded due to AIM9L and aggressive tactical flying.
