In December 2016, it was announced that Constantine the Great Airport airport began overhaul of its terminal by expanding check-in and boarding space, as well as building a new exterior and fixing the roof. The project is being funded jointly by the Government of Serbia and local authorities. Furthermore, the Serbia and Montenegro Air Traffic Services Agency (SMATSA) plans to start construction of a new control tower next year and will invest a million euros in an instrument landing system (ILS), which provides guidance to aircraft approaching and landing on a runway during low ceilings or reduced visibility due to fog, rain or snow.
