On 30 May, two Super Étendards, one carrying Argentina's last remaining Exocet, escorted by four A-4C Skyhawks each with two 500lb bombs, took off to attack the carrier HMS "Invincible". Argentine intelligence had sought to determine the position of HMS "Invincible" 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 ship to disguise her 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 HMS "Exeter", and while the fate of the Exocet has never been established beyond doubt, the crew of HMS "Avenger" claimed that their 4.5" gun had shot it down. No damage was caused to any British vessels.
