Military expert Artsrun Hovhannesyan gave high assessment to the excellent performance of Armenian air defence forces in Karabakh war years, characterizing it as the best in the region.

As the head of the air defence department at Military Aviation Institute after Armenak Khamfertsyan, Haykaz Gevorgyan noted, rearmament is another successful step by Armenian air defence forces. Even before Armenia purchased S-300 missile systems, Armenian experts had excellent command of them. During post-Soviet period, Armenian air defence forces showed more progress than those of NATO, he said.
