Air defense in places of department of freedom (in the regions of Transbaikal and the Far East in 1941-1945)

Protection of production facilities from the action of combat aircraft was relevant during the Great Patriotic War. Despite the fact that the eastern regions of the Soviet Union - east of Lake Baikal, were inaccessible to the German Air Force, but their proximity to Manchuria occupied by Japanese troops, caused concern to the Soviet leadership. In places of detention located in Transbaikalia and the Far East, NKVD air defense units were created to protect industrial enterprises, law enforcement personnel, prisoners themselves from the possible consequences of air attacks, as well as the spread of fires, the prevention of riots and escapes.
