 Through the Defence Act of 1942, it was decided to separate the air defense from the artillery, to form its own branch, the air Swedish Air Defense Troops ("Luftvärnstrupperna").The change resulted in the regiment being assigned a new designation, Östgöta Anti-Aircraft Regiment (Lv 2).But also that the detachments in Malmö and Sundsvall were separated from the regiment and formed independent units, the Scanian Anti-Aircraft Corps ("Skånska luftvärnskåren", Lv 4) and Sundsvall Anti-Aircraft Corps ("Sundsvalls luftvärnskår", Lv 5).
