The 105th Aviation Brigade (Serbo-Croatian: 105. ваздухопловна бригада, 105. vazduhoplovna brigada) was formed from the disbanded Yugoslav 105th Fighter-Bomber Aviation Regiment in the spring of 1993 by the Serbian Army of 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 due to the aircraft had same roundels.

Aircraft from Udbina airport have taken part in wars in both Croatia and Bosnia because the Republika Srpska Air Force aircraft at Banja Luka airport were unable to take off under the no-fly zone over Bosnia and Herzegovina.

In several combats Gazelle Gama anti-tank helicopters were very effective destroying Croatian army tanks.

[citation needed] At the time of the Croatian Operation Storm most of aircraft in flying condition had retreated to Banja Luka.
