Challenges to national defence in contemporary geopolitical situation

The aim of the research was to assess the possibility of using various types of civil aircraft for terrorist attacks. The main methods were: analysis and synthesis, analogy, generalization, comparison and inference. The research was based on the analysis of the literature as well as normative and doctrinal documents. Scientific observation where used, which focused on practical examples and attempts to use civil aircraft by terrorists to attack civilian objects from 2001 to 2020. Considering the large diversity of each types of aircraft, a criterion analysis was used to evaluate them in terms of their suitability for terrorist attacks. As a result of the conducted analytical research, three groups of aircraft were selected, which are particularly predisposed as potential tools of terrorist attacks on civilian objects. The first group consists of large-size structures such as passenger and transport planes, the use of which in attacks may cause the greatest losses, both material and human. The next group consists of small-sized light and very light airplanes, microlight, unmanned aerial vehicles and radio-controlled models. This type of aircraft and flying machines are in a period of dynamic development and, at the same time, of great interest on the part of terrorist groups. It was also found that in the case of attacks using explosives or taking into account aviation fuel (which, as a result of an aircraft collision with an object, usually explodes), greater possibilities give large aircraft, such as passenger and transport aircrafts.
