Abstract: The increasing complexity of the tasks assigned to modern anti-aircraft missile systems and the conditions for their use necessitate taking into account the human factor and revising the requirements for operational personnel, due to the increasing impact of the psychological component of their professional activities. The effectiveness of the professional activities of operators of anti-aircraft missile systems is determined by the level of expression of a number of professionally important qualities. The formation of a set of informative standardized psychodiagnostic methods that make it possible to determine the level of professionally important qualities of operators of anti-aircraft missile systems at the stages of selection and training is an urgent task. The study of the effectiveness of the use of tests and questionnaires proposed in these works, their reliability and validity, made it possible to identify a set of the most suitable psychodiagnostic techniques. The selection of psychodiagnostic techniques was carried out taking into account their practicality in relation to the peculiarities of operator activity. This article updates the integral professionally important qualities characteristic of the professional activities of operators of anti-aircraft missile systems. The author pays special attention to the results of the study of existing methods for assessing professionally important qualities, and provides a set of selected psychodiagnostic methods for identifying and studying the professionally important qualities of operators of anti-aircraft missile systems. The use of selected psychodiagnostic techniques at the stages of selection and professional training of operators of anti-aircraft missile systems will reduce the screening of unsuitable persons during the training process, reduce the accident rate of serviced equipment due to personnel errors, increase the reliability of control systems, and also reduce the cost of training operators.
