During the 1982 Falkland Islands War, the French-made Exocet antiship missile proved to be a particularly lethal weapon for the Argentine forces. Although Argentina possessed only a small number of these missiles, they significantly impacted the conflict by demonstrating the vulnerability of the British naval task force.12

The most notable impact occurred on May 4, when an Exocet missile fired from an Argentine Super Etendard aircraft struck and sank the British destroyer HMS Sheffield. Later in the campaign, on May 25, another Exocet attack successfully penetrated fleet defenses to strike the supply ship Atlantic Conveyor.12

These attacks highlighted the dangers posed by modern air-launched missiles to surface vessels, especially those lacking advanced electronic countermeasures or close-in weapons systems. While these strikes caused significant damage and loss of life, they were ultimately unable to sink the British aircraft carriers or prevent the British from establishing a beachhead and successfully retaking the islands. Military strategists continue to view the use of such missiles as a defining element of the conflict's naval engagements.12
