The purpose of this work is to analyse and study the possibilities of using unmanned aerial vehicles (UAVs) for military purposes. Methodology. One of the important tasks of using UAVs is topographic aerosurveying for processing large-scale plans, which, as confirmed by the experience of military actions, are a necessity to work with them by appropriate composition. But this process is rather complicated, since many requirements for carrying out the aerosurveying must be observed such as adhering to the height of surveying for the scaling of aerial images, and to the stabilization of the aircraft to reduce angles of inclination and speed for receiving longitudinal overlap. All these factors lead to rapid detection of an object and its destruction. Therefore, the authors have made an analysis of modern type of UAVs that are used for aerosurveying of military objects. Also it presented a detailed classification of military UAVs, established a list of tasks that they can perform, and made appropriate conclusions. Requirements for the establishment of military UAVs have been developed. The research of the developed UAV Arrow has been carried out in order to confirm the possibility of its application in aerial surveying purposes. Results. To determine the aerodynamics performed by both the Arrow aircraft and the Trimble UX5 UAV aircraft in aerating of the same plot. A comparative analysis of the values of the angles of yaw, roll, and pitch of UAV Arrow and Trimble UX5 for each route is made. Scientific novelty and practical significance. UAV currently perform different tasks in many industries of the economy and defence of countries. The main advantage of using UAVs in military affairs is that they can perform their tasks in automatic or semi-automatic modes with minimal human participation in the control process. Taking into account the military conflict in the east of Uraine, this issue becomes particularly relevant, since the determining of peculiarities of using of UAVs for military purposes will allow: to reduce losses among both the military and the civilian populations which are often attacked; to conduct invisible reconnaissance of ground objects and enemy targets in enemy occupied territory; to determine targets for attack; to make a point artillery or air strike on enemy targets and subsequently to control the results of the attack; to conduct radio-electron struggle; to detect and to neutralize enemy's UAVs.
