However, experts note that it is unlikely that this kamikaze drone will cover that distance, because such a weight and speed will require a commensurate consumption of fuel, and a number of other factors indicate that it can fly about a thousand kilometres."However, according to the spokesman for the Air Force Command, strikes can be expected from other directions as well, because the Russians could have sent drones to occupied Crimea and Belarus.The Ukrainian Armed Forces need various forms of air defence in order to carry out this mission; in particular, they need anti-aircraft guns and large-calibre machine gun systems, which can shoot down drones at different stages.Ihnat confirmed that Russia has switched from using Kh-101, Kalibr, Kh-555 and Iskander high-precision missiles, which cost millions of dollars, to unmanned aerial vehicles.According to official data, three infrastructure facilities were damaged in the city as a result of the night attack by drones; there were no civilian casualties, and the life of the one person who was injured is not in danger."
