What would the Royal Navy have done if the Harrier and STOVL fighter concept had not existed?
Short answerIt would still attempt the Falklands operation with far greater risk, and a poor result would probably revive conventional carrier construction.
NotesThe task force would lack its most important local fighter cover, although Britain would still attempt the operation. Invincible-class ships might operate closer to San Carlos as helicopter carriers, while retained Tiger-class cruisers could contribute dense three-inch antiaircraft fire. The United States might intervene if Britain requested help, but domestic political pride could delay that request. A badly damaged or defeated task force would create overwhelming pressure for a new full-strength carrier program after the war.
