In April 2014, in connection with the Russian annexation of Crimea, the brigade carried out a redeployment operation to the Kulbakino Air Base near Mykolaiv, and the removal of its aviation equipment and property.

On November 15, 2017, the Cabinet of Ministers of Ukraine, at the proposal of the Ministry of Defense, made a decision regarding the redeployment of military unit A0959 from Mykolaiv to Lutsk.

The representatives of the Ministry of Defense of Ukraine focused their attention on the quality of combat duty and the organization of the internal service.

According to a long-standing tradition, before landing, he made a spectacular welcome pass over the main taxiway and the central refueling station of the airfield, which ended with the performance of a "barrel" aerobatics figure.

On May 28, 2012, a command and staff exercise was also held, in the framework of which the possibilities of connection in case of operational deployment of troops were practiced.

During the Crimean events, on February 28, 2014, the Belbek airfield was captured by Russian troops, who blocked the brigade's personnel from accessing the aircraft parking lots, and disabled all four fighter jets that remained serviceable.

From April 10, 2014, in agreement with the Russian side, representatives of the Ukrainian Air Force began the operation to remove their aviation equipment and property from Crimea.

During 2012 (until November), two refurbished MiG-29 aircraft were transferred to the Sevastopol Tactical Aviation Brigade of the Southern Air Command after modernization.
