Ensuring the world-class tactical and technical characteristics of armored vehicles is an extremely important and urgent problem in the field of national security and defense. This is due to the enormous potential of Ukraine's armored vehicle industry, which has not yet been realized in the design and development of the production of these vehicles for various reasons. One of the main problems is the lack of methods and models to substantiate the parameters of these vehicles and the properties of materials for the manufacture of the main components, primarily armor hulls and transmissions, at the stage of design research. This work involves developing the theoretical foundations and conducting research to determine the response of armored vehicle components to various factors and to determine the requirements for design solutions for their components. An extremely important factor is, for example, the prevention of critical deformations that occur in armored vehicles when exposed to munitions. Existing models do not allow for an adequate assessment of the degree of protection under the influence of various factors, which leads to fundamentally incorrect design decisions. Consequently, a new, relevant, and important scientific and technical problem arises - the study of processes and states of armored vehicles in combat use to improve their tactical and technical characteristics. The theoretical foundations of such research are described in this paper. Their significance is especially growing in the current situation in the presence of hostilities that require the manufacture and supply of military equipment with high tactical and technical characteristics. In turn, achieving the world level of these characteristics is impossible without a number of studies, in particular, based on the approach described in this paper, as a matter of priority. Research on this basis is aimed at scientific substantiation of advanced technical solutions for military equipment.
