Formed in Canada as No. 125 (Fighter) Squadron on 20 April 1942, the unit was the fourth of six home squadrons transferred overseas (complete in personnel but without aircraft) in preparation for the Allied invasion of Europe, and was redesignated No. 441 (Fighter) Squadron at Digby, Lincolnshire, England on 8 February 1944. It flew Spitfire aircraft on offensive and defensive air operations and, after D-Day, gave close support to ground forces in North-West Europe. In May 1945, the unit was re-equipped with Mustang aircraft for long-range bomber escort duty, but
was not operational when hostilities ceased in Europe. The squadron was disbanded at Molesworth, Huntingdonshire on 7 August 1945.
