Planning for the raid called for a bomb run in a 35° cut across the runway, with the aim of placing at least one bomb on the runway and possibly two. The main purpose in doing so was to prevent the use of the runway by fast jets; in this respect the raid was successful as the repair to the runway was botched and subsequently there were several near accidents. The fact that the British forces could penetrate Argentine air defences and attack the airfield had the desired effect in relation to preventing fast jet usage of the Port Stanley airstrip as the Argentine military command could not risk stationing its fast jets and the infrastructure necessary to operate them on the islands if they could be destroyed on the ground, irrespective of the operational status of the runway. Admiral Woodward considered it vital to keep fast jets from using Port Stanley, to reduce the threat of air attack on the British aircraft carriers. Starting on 1 May, the Royal Navy attacked Port Stanley with aerial bombing by Sea Harriers and naval bombardment, in order to hamper Argentinian repair efforts. The Argentinians left the runway covered with piles of earth during the day, leading to claims this caused British intelligence to surmise that repairs were still in progress and misleading the British as to the condition of the airfield and the success of their raids.
