By the end of 1943, No. 4 Group had been entirely equipped with the Halifax, and would continue to operate the aircraft until the end of the war. No. 6 Group, formed of Royal Canadian Air Force (RCAF) squadrons, also adopted the Halifax around the same time, and would go on to operate it in each of its 14 squadrons, although it was never solely equipped with the type. At its peak strength, Bomber Command operated a total of 76 Halifax-equipped squadrons.
