Ark Royal and the usefulness of an older carrier

Which 1969 Royal Navy ship would best serve the fleet today?

The answer selects Ark Royal as a useful third carrier if modernized, because aircraft-operating capability matters more than a hull's age alone.

Ark Royal is proposed as a potentially useful additional carrier if maintained and modernized, even though she could not match a Queen Elizabeth-class air group. The answer emphasizes her Buccaneer and Phantom-era capacity, then makes the broader point that age matters less than whether a carrier can safely operate the aircraft a navy needs. A smaller modernized air group could still add meaningful availability when the two larger carriers were committed elsewhere. It is a force-availability argument rather than a claim that older ships are automatically adequate.
