Which preserved Royal Navy ship would have made the greatest difference in the Falklands War?
Short answerHMS Eagle or HMS Ark Royal, chiefly because Gannet airborne early warning would make the air war much easier to manage.
NotesHMS Eagle or HMS Ark Royal takes priority over Vanguard in this preservation counterfactual. The essential requirement is Fairey Gannet airborne early warning aircraft, with Phantom or Buccaneer strike power treated as secondary. A carrier able to sustain Gannet coverage could give Sea Harriers and the task force a much clearer picture of approaching threats. Vanguard remains the second choice, but the priority given to early warning shows how information and detection can matter more than the most dramatic weapons.
