In the Falkland Islands War, air superiority was a critical factor because it directly influenced the ability of both sides to conduct operations and protect their assets. The conflict highlighted the vulnerability of surface ships to modern antiship missiles and air attacks, particularly when naval forces lacked adequate long-range air cover.123

For the British, maintaining control of the airspace was essential to protect their two aircraft carriers, the loss of which would have likely forced a withdrawal from the conflict. Because the British had limited air cover—relying on a small number of Sea Harrier jets—they were forced to use destroyers and frigates as radar pickets to detect incoming threats. This left these screening ships highly vulnerable, as demonstrated by the sinking of the HMS Sheffield by an Argentine Exocet missile.12

Conversely, the Argentine air forces, despite operating at the extreme edge of their combat radius and lacking advanced electronic countermeasures, were able to inflict significant damage on the British fleet. Ultimately, the British were able to maintain sufficient control of the airspace to enable their amphibious landings and sustain their supply lines, which proved decisive in retaking the islands.12
