Based on the experience of the Russian-Ukrainian war, there is a tendency to increase the number of unmanned aerial vehicles used to destroy equipment, personnel, and infrastructure. For this purpose, unmanned aerial vehicles such as barrage munitions, kamikaze, drop drones, etc. are used. The share of losses of weapons and equipment, as well as personnel, caused by such weapons has become the largest compared to other means of destruction. To counteract such means, various anti-aircraft missile systems, electronic warfare equipment and mobile fire groups are used. The most effective way to defeat unmanned aerial vehicles is to hit them with a large number of destructive elements (fragments). Taking into account the ratio of the cost of unmanned aerial vehicles and means of their destruction, in particular anti-aircraft missile munitions, the paper proposes the use of fragmentation explosive devices of directed action to defeat attack unmanned aerial vehicles according to the "effectiveness-cost" criterion. The article presents an analysis of studies of the effectiveness of the use of directed-action fragmentation munitions. A study of the feasibility of using directed-action fragmentation engineering ammunition of the MON series mines is carried out. On the basis of the mathematical model of the flight of a fragment, taking into account its shape, a methodology for calculating the main parameters of fragmentation explosive devices of directed action for the destruction of air targets such as unmanned aerial vehicles is proposed. Mathematical calculations are presented to determine the main characteristics of fragmentation explosive devices of directed action for defeating unmanned aerial vehicles, taking into account the external trajectory measurements of the target and the factors that affect the formation of the fragmentation field (zone). Schemes of deployment of fragmentation explosive devices of directed action for the protection of objects are proposed.
