A methodological approach to forecasting the cost costs at the main stages of the life cycle of a sample of weapons and military equipment, as one of the most important carriers of the capabilities of military organizational-staff formations, is proposed, which is carried out when substantiating measures for developing the capabilities of troops in the course of long-term and medium-term defense planning. The methodological approach is based on the use of the concept of a typical distribution of the cost of the life cycle of a sample by stages and stages, which allows in a formalized form to link costs at each stage of the purchase price of a serial product of a sample of weapons and military equipment of a specific type and type, taking into account the choice of a specific way of obtaining weapons and military equipment. It is proposed to forecast the volume of necessary costs at the stage of operation and support, taking into account the uneven distribution of these costs during this stage of the life cycle of a separate product. For this, it is proposed to divide the entire period of the duration of the operation stage into two main parts. The first part corresponds to the operating conditions of the product with a constant failure rate of the equipment after the completion of a short running-in process, and the operating costs per unit of time on it are considered the same throughout its duration. A formalized expression is proposed for obtaining the predicted value of these costs depending on the purchase price of the product. In the second part of the period of operation and support of a product of weapons and military equipment, operating costs per unit of time change over time according to an exponential law, reflecting the fact that operating costs increase with an increase in the failure rate as it approaches the assigned service life, which corresponds to the laws, known from the general theory of reliability of technology. The specifics of forecasting the costs of operation and support of a product obtained by import and which has already been in operation and has a residual service life have been determined.
