How would the battlecruisers from the 1914 Battle of the Falkland Islands fare in the 1982 Falklands War?
Short answerThey would need constant Harrier protection against aircraft, but their 12-inch guns could deliver exceptionally heavy naval gunfire support.
NotesThis counterfactual moves the battlecruisers associated with the 1914 Falklands victory into the 1982 campaign. Their limited armour and lack of modern air defence would make independent survival unrealistic. A standing Sea Harrier combat air patrol could protect them while the old ships contributed their uniquely heavy artillery. In that role, their 12-inch batteries could have transformed shore-fire support even though the hulls were unsuited to the modern threat environment.
