During the Second World War, Hal Far airfield was one of the main targets for the Luftwaffe and the Regia Aeronautica and suffered several bombings during the blitz. On July and August 1940 in the beginning of the Siege of Malta, the Italian air-raids managed to damage several squadron aircraft. As the raids intensified during 1942 more damage was inflicted on the airfield and the squadrons, present on the airfield. On one particular attack on Hal Far by Junkers Ju 88s, a Fairey Swordfish was badly damaged. Further raids during January 1942 resulted in the destruction at Hal Far of two other Swordfish and a Blackburn Skua, and damaged 15 Hurricanes, three other Swordfish and a Fairey Fulmar. Further damage to aircraft, airfield buildings and loss of personnel resulted during attacks in 1942 and 1943, with the last bombing being recorded on 21 May 1943.



Hal Far had been the first Maltese airfield to be bombed on 11 June 1940. During this period, 2,300 tons of bombs were dropped on the airfield, nevertheless it was never made unservicable, due to the efficiency of the airfield repair parties. On the airfield itself the ground crew casualties numbered 30 killed and 84 injured. Various officers and Maltese civilian employees were awarded the George Cross, George Medal and other awards for their courage and bravery in the face of enemy action. With enemy air raids practically at an end, and as aircraft became heavier and traffic had increased significantly, paved runways and taxiways were added to the airfield, together with the completion of runways 13/31 and 9/27.
