What if Britain kept two Audacious-class carriers into the 1980s and sent them to the Falklands?
Short answerThey greatly improve air control and may deter Argentina from invading at all.
NotesTwo modernized Audacious-class carriers would bring fixed-wing airborne early warning, longer-range fighters, and a much larger strike group than Hermes and Invincible. That would permit a sustained combat air patrol, earlier detection of Argentine raids, and heavier attacks on positions ashore. British losses from air attack would probably fall sharply. More fundamentally, Argentina timed the invasion for a moment of perceived British weakness, so the continued existence of such carriers might prevent the war from beginning.
