History The unit was raised on 1 October 1939 in Stockholm as the Östgöta Anti-Aircraft Artillery Regiment's Detachment in Stockholm (A 10 S). On 1 October 1941, the detachment was separated from the Östgöta Anti-Aircraft Artillery Regiment and became an independent unit under the name of Stockholm Anti-Aircraft Regiment (A 11). As part of the Defence Act of 1942, the regiment was transferred in 1942 to the newly formed air defence military branch (Luftvärnstrupperna) as the Stockholm Anti-Aircraft Regiment (Lv 3).
