How another Falklands invasion date changes the carrier debate

What earlier or later date would make an Argentine attempt on the Falklands most consequential?

An attack during the 1960s CVA-01 decision could force Britain to retain a large carrier, while the mid-1980s might leave fewer immediate British resources available.

A 1960s invasion during the CVA-01 decision would confront the British government with direct evidence that a large carrier was still needed. Cancellation would become much harder to defend while an overseas territory required recovery. Waiting until about 1985 creates a different counterfactual because fewer of the 1982 resources might remain ready. The 1960s are the most interesting date because the crisis could reshape carrier policy as well as the campaign. This brief counterfactual does not build a complete order of battle for either alternative.
