Activated in 1943, the group was initially assigned to protect coastal and port facilities in the European Theater, notably supporting the Normandy landings and subsequent advance across France. The 9th AAA Group was equipped with a mix of anti-aircraft guns, including the 90mm and 40mm Bofors, to counter enemy aircraft and V-1 flying bombs.
