The 105th Aviation Brigade () was formed out of the disbanded Yugoslav 105th Fighter-Bomber Aviation Regiment in the spring of 1993 by the Military of Serbian Krajina at Udbina Airport. Its accurate organization is unknown, and it's not exactly clear whether the brigade was part of Republika Srpska Air Force, because the aircraft had same roundels. It consisted from at least one combat squadron nicknamed "Kobre" (Cobras - same as former 249th Squadron) and 56th Mixed Helicopter Squadron. Commander of brigade was Ratko Dopuđa.
