On 30 May, two Super Étendards, one carrying Argentina's last remaining air-launched Exocet, escorted by four A-4C Skyhawks each with two 500lb bombs, took off to attack "Invincible". Argentine intelligence had sought to determine the position of the carriers from analysis of aircraft flight routes from the task force to the islands. However, the British had a standing order that all aircraft conduct a low level transit when leaving or returning to the carriers to disguise their position. This tactic compromised the Argentine attack, which focused on a group of escorts 40 miles south of the main body of ships. Two of the attacking Skyhawks were shot down by Sea Darts fired by , with HMS "Avenger" claiming to have shot down the missile with her 4.5" gun (although this claim is disputed). No damage was caused to any British vessels. During the war Argentina claimed to have damaged the ship and continues to do so to this day, although no evidence of any such damage has been produced or uncovered.
