The squadron was equipped with the Supermarine Spitfire Mk.IX in April 1944, and in June began anti-V1 patrols, shooting down 39 flying bombs. Missions were also flown over the Falaise Gap, strafing targets of opportunity. Later in the year it reverted to bomber escort duties, based at Haldegham. It was involved in supporting Operation Market Garden : the parachute drops into the Netherlands, and later in support of the Allied counter-offensive in the Ardennes. The squadron dropped 250 lb bombs on to 'Key Points' (KPs), directed by radar to counter the adverse weather conditions. In May 1945 it converted to the Spitfire Mk.XXI, but these were only used operationally to cover landings on the Channel Islands.
