On the night of 27 to 28 June 1991, following an attack by Slovenian forces, 67 aircraft were flown out of Cerklje to Zadar-Zemunik air base in Croatia. Among others, the Yugoslav People's Army completely withdrew the 474th vazduhoplovna baza (Air Base) from Slovenia, a unit that was responsible for Cerklje ob Krki Air Base. During the withdrawal every movable object, including the runway lighting and ILS systems, were dismantled and removed. On 12 August 1991, the 474th Air Base was re-established in Banja Luka and became responsible both for Mahovljani and Zaluzani airfields.
