In the graduate thesis „Air Operations in Kosovo in 1999“, Operation Allied Force was presented as the dominant campaign of the NATO alliance in resolving the humanitarian crisis in Kosovo. The historical cause of the conflict between Serbs and Albanians from Kosovo was explained as well as the reason for NATO's decisive intervention, due to attempts to ehnically cleanse Kosovo Albanians as a minority people (at the level of the Federal Republic of Yugoslavia). The operation was prepared months in advance for implementation in phases, strikes on military, political and economic targets. The dominance of Allied air power in airspace control, the use of state-of-the-art air technology, weapons and ammunition, surveillance and surveillance systems, and the operational use of space stations for signal transmission and target positioning is described. New technical advances and rules for the use of fire have led to a reduction in civilian casualties. The operation was successful, and the achievements and lessons learned were systematically studied to improve in air conflict management and control.
