The Baku Air Defence Army (Russian: Бакинская армия ПВО) was formed on the Eastern Front of World War II, following the decree of the USSR State Defense Committee of April 5, 1942. Previously known as the Baku Air Defence Corps, its main objective became sheltering the Baku oil fields from German raids. The Wehrmacht had been planning the capture of the oil field under the codename Operation Edelweiss. During the intense German air reconnaissance in May–October, 1942 the Army included the 8th Air Defence Fighter Corps, seven anti-aircraft regiments, one anti-aircraft machine-gun regiment, a searchlight regiment, a barrage balloon regiment and some other units. During its actions, the Army downed eight aircraft.
