What difference would Vanguard and two Malta-class carriers have made if Britain retained them through the Falklands War?
Short answerThey might have prevented the invasion through deterrence; if not, they would have brought a much stronger carrier air group and an extensively different supporting fleet.
NotesA visible force built around Vanguard and two large carriers would make Argentine leaders reconsider whether the Falklands could be seized and held. If deterrence failed, the carriers could operate a far larger and more capable air group than the historical light carriers. Their continued service would also reshape escorts, replenishment ships, dockyard policy, and designs such as the Type 82. The counterfactual therefore changes the whole fleet structure, not merely the number of aircraft present in 1982.
