The wartime Ark Royal reappears during the Falklands War

What happens if HMS Ark Royal disappears before her fatal torpedo hit and reappears fully crewed and supplied as the Falklands are invaded?

She could probably operate Harriers and helicopters after a rapid ski-jump and communications refit.

The counterfactual saves the wartime Ark Royal from her fatal torpedo attack and returns her fully crewed and supplied when the Falklands are invaded. She could probably operate Harriers and helicopters. A ski-jump would have to be fitted unusually quickly to support the proposed air group. Compatible communications equipment would also be needed before she could work with the 1982 force.
