Abstract
The relevance of the study is emphasised by the need to investigate and develop effective strategies for protecting critical state infrastructure in the context of the Russian-Ukrainian war of 2022. The purpose of this study is to evaluate the effectiveness of interaction between the means of physical and electronic influence in the context of protecting critical infrastructure facilities of the energy sector from air strikes. The object of research is the system of protection of critical facilities of the state’s energy sector. Research methods included the use of system analysis, the development of strategies for determining the optimal locations of the means of physical influence, and the use of mathematical modelling. Research in the field of interaction and simultaneous use of physical and radio-electronic means included a theoretical analysis of abstract objects and their relationships. These objects were designed to create an idealised description and investigate possible scenarios, as well as to determine optimal actions in specific situations. This study examined in detail the possibilities of improving the effectiveness of protecting important energy facilities from air strikes through the use of combined strategies such as anti-aircraft fire and fire protection. Methods for determining the optimal locations of the means of physical influence were analysed, which allowed predicting expected results when using them together. It was developed evidence-based recommendations for the effective integration of these methods, which is an innovative approach to the problem. The means of physical influence included small arms, which were part of the armament of the Armed Forces, and interceptor drones. Electronic means of influence included technical means of radio frequency warfare and electromagnetic guns. The practical significance of this study lies in the fact that it presents specific strategies and technological solutions for comprehensive protection of critical infrastructure facilities from air strikes. This paper can serve as a basis for developing effective security and protection policies in countries and regions, helping to improve overall sustainability and security
