The squadron replaced its Hurricanes with Supermarine Spitfires in April 1941. In November, "Treble One" again relocated to RAF Gibraltar for support of Operation Torch, the invasion of North Africa. In a similar role it moved to Malta in June 1943 to support Operation Husky, the invasion of Sicily. No. 111 (F) Squadron moved through Italy with the advancing Allied ground forces and remained there until the end of the war, after which it moved to Austria. The squadron disbanded in May 1947. 269 aircraft were claimed shot down, making the squadron one of the top RAF scorers for the war.
