Would the Falklands War have exposed the same weaknesses in a US carrier force?
Short answerThere would still have been difficulties, but Hawkeye airborne early warning would have addressed an important British shortfall.
NotesThe answer does not claim that the Falklands would have been simple for an American force, but it identifies a major difference: US carriers operated E-2 Hawkeye airborne early-warning aircraft. That capability would have made approaching threats easier to detect and manage before they reached the task force. The discussion notes that a radar-equipped helicopter was conceptually available to Britain before the war. Rapid postwar development showed that the idea was feasible, but it had not been assembled and fielded when the need became urgent.
