 Gotland's air defence has its origins in the Stockholm Anti-Aircraft Regiment's (Lv 3) artillery battery detachment on Gotland (Lv 3 G), established in 1944.When Stockholm Anti-Aircraft Regiment moved to Norrtälje in 1953, the responsibility for the artillery battery on Gotland was transferred to Östgöta Anti-Aircraft Regiment (Lv 2) in Linköping and thus the unit received the designation Lv 2 G. Östgöta Anti-Aircraft Regiment was disbanded in 1962.Lv 2 G took over its ensign and traditions on 2 April.
