Actually the Argentinian Navy pilots (not airforce) were the first to use airborne launched anti-ship missiles in a modern conflict. The combination of the Super-Etendard planes and the Exorcet missiles used by the Argentinians were devastating to the Royal Navy. Even with no proper training and with only a limited supply of missiles (due to the French embargo), the Argentinians were able to sink several British ships, including their most modern warship at the time, the Type 42 destroyer HMS Sheffield. If they had a proper stock of the Exorcet missiles (they only had about 6 units), they would have probably won the war, since at the time, the Royal Navy lacked adequate counter-measures against the Super-Etendard + Exorcet combination.
