At 10:35, the Neptune climbed to 1170 metres (3,838.6 ft) and detected a large and two medium-sized contacts at the coordinates 52º 33 55 South, 57º 40 55 West map. A few minutes later, the Neptune contacted both Super Étendards with this information. Flying at very low altitude, around 10:50, both Super Étendards climbed to 160 metres (524.9 ft) to verify these contacts, but, not finding any, decided to continue. 25 miles (40.2 km) later they climbed again and, after a few seconds of scanning, the targets appeared on their radar screens. Both pilots loaded the coordinates in their weapons systems, turned back to low level, and after last minute checks, launched their AM39 Exocets at 11:04 from 20 to 30 mi (32.2 to 48.3 km) away from their targets. The Super Étendards did not need to refuel from the KC-130 again, which had been waiting, and landed at Rio Grande at 12:04. Supporting the mission were an Air Force Learjet 35 as a decoy and two IAI Daggers as the KC-130 escorts

Sheffield picked up the incoming missiles on her outmoded Type 965 radar (an interim fitting until the Type 1022 set was available), and the Operations Officer informed the Missile Director, who queried the contacts in the ADAWS 4 fire control system. The launch aircraft had not been detected as the British had expected, and it was not until smoke was sighted that the target was confirmed as sea skimming missiles. Five seconds later, an Exocet

. Ironically, the Exocet missile which hit Sheffield did not detonate, but the missile severed the high-pressure fire main onboard, and the resultant fire caused by burning propellant ignited diesel oil from the ready-use tanks in the Engine Room, and other inflammable materials used in the ship's construction. These fires burned unchecked for a number of days after the ship was abandoned.

 report into the sinking of the Sheffield concluded that: "Evidence indicates that the warhead did not detonate". Some of the crew and members of the Task Force believe however that the missile's 165 kilogram warhead did in fact detonate upon impact. This was not the case, as an Exocet is filled with a delay proximity fuse, and is designed not to detonate on impact. But irrespective of this the impact of the missile and the burning rocket motor set Sheffield ablaze. Some accounts suggest that the initial impact of the missile immediately crippled the ship's onboard electricity generating systems, but this only affected certain parts of the ship, which caused ventilation problems. The missile strike fractured the water main, preventing the anti-fire mechanisms from operating effectively, and thereby dooming the ship to be consumed by the raging fire.

Over the next 6 days from 4 May 1982 onwards, some 5 inspections were made to see if any equipment was worth salvaging. Orders were issued to shore up the hole in Sheffield's starboard side and tow the ship to South Georgia .

, both of which had aluminium superstructures, probably also had an effect on this belief though these cases are again incorrect and the presence of aluminium had nothing to do with their loss. In both cases, it is likely the ships would have been lost in any event, due to the amount of explosives involved in such small ships, though aluminium fires did break out. Ardent in particular took a severe pounding, suffering eleven bomb hits, five of which exploded; no ship of her type of any era would have been able to survive such an attack. The fires on these ships did result in one clear change, which was the shift away from the nylon

The official report into the sinking of the Sheffield, recently disclosed under UK Freedom of Information laws after an extensive campaign by ex-RN personnel, severely criticised the ship's fire-fighting equipment, training and procedures and certain members of the crew.
