The eastern and Upper Norrland air defence districts were established on 1 July 1942, the others a year later.

[2] The task was also to maintain the administration of training sites and wartime airfields as well as facilities and depots at these in peacetime, as well as to prepare the Swedish Air Force's basing in war.

[3] The Southern Air Defence District coincided with the I Military District,[4] covering South Sweden and Småland and the islands which consisted of Malmöhus, Kristianstad (now joined as Skåne County), Blekinge, Kronoberg, Jönköping and Kalmar counties.

[2] The main duties of the air defence district commanders during peacetime were war preparation work, including planning of the base and supply service as well as air defence warning service, as well as voluntary training for the air defence warning service, as well as management of training airfields and certain supply depots.

The base service included station service, air traffic control, ground air defence and ground defence (in cooperation with certain forces from the army), signal service, military camp and provision, medical care, transport and airfield repairs (some) and snow removal.
