Operational barriers to borrowing a U.S. carrier for the Falklands

Would an offered U.S. carrier have been useful to Britain in the Falklands War?

Probably not as an immediate solution; the crewing and aircraft-integration burden was huge, while an Aegis cruiser would better address an urgent air-defence gap.

A U.S. carrier was never formally offered, and Britain would have struggled to use one quickly. A large American carrier required far more crew, pilots, and support than the Royal Navy could provide, while a smaller LHD offered little beyond Britain's existing ships. An Aegis cruiser would have addressed the more urgent air-defence gap because British planning had assumed American Aegis support.
