Later that morning, twelve 800 Naval Air Squadron Sea Harriers were dispatched from the aircraft carrier to attack targets on East Falkland. Nine of the aircraft struck Port Stanley Airport and dropped 27 bombs on the airfield and its defences. The bombs set a stockpile of fuel on fire and may have slightly damaged the runway. One of the Sea Harriers was struck by a 20 mm anti-aircraft round, which damaged its fin and tailplane; the aircraft managed to return to "Hermes" and was quickly repaired. The Argentine air defence headquarters incorrectly assessed British losses as three aircraft destroyed.
