Currently, there is a trend of digital information processing in electronic weapons systems and military equipment. Software-controlled means of communication are being implemented. This requires new approaches in diagnosing them during maintenance, which are significantly different from the process of finding defects in analog tools.Particular attention is paid to the introduction of modern advances in technical diagnostics and metrology. The possibility of using special methods for assessing the technical condition of digital devices (energy-static, energy-dynamic, electromagnetic), both separately and in combination. This slightly increases the average recovery time, but significantly affects the achievement of the required value of a comprehensive indicator of product reliability - its readiness factor.For the first time, the possibility of classifying electronic systems as "absolutely reliable" due to the peculiarities of metrological and diagnostic software is considered. The influence of controlled variables on the value of the product readiness factor is investigated. Depending on the operating conditions of the repair body, the permissible values for the qualification of specialists (average time of inspection and troubleshooting), as well as for the metrological reliability of measuring equipment are justified.According to the results of research, an algorithm for providing the necessary values of reliability indicators of products, both during their design and during operation and recovery in military conditions. It is shown that the greatest influence on the value of the reliability of products has the training of specialists of the repair body, their ability to fully use the capabilities of modern measuring equipment.The article considers the possibility of using methods for diagnosing digital electronic systems and provides an assessment of the quality of diagnostic software for the reliability of systems as a whole.
