The Italian Co-Belligerent Air Force (Aviazione Cobelligerante Italiana, or ACI), or Air Force of the South (Aeronautica del Sud), was the air force of the Royalist "Badoglio government" in Southern Italy during the last years of World War II. The ACI was formed in Southern Italy in October 1943 after the Italian Armistice in September. As by this point the Italian Kingdom had defected from the Axis and had declared war on Germany, the ACI pilots flew for the Allies.
