PURPOSE. The article deals with the age and model composition of the fire truck fleet in fire and rescue units. The dynamics of changes in the age composition of the fire truck fleet in the period from 2011 to 2021 has been studied. Simulating the dynamics of changes in the fire truck fleet has been carried out, taking into account the approved program for technical re-equipment of the units of EMERCOM of Russia with fire, rescue, special and aircraft equipment until 2030. The relevance of the issue of restructuring the fire truck fleet of EMERCOM of Russia has been confirmed and ways for further development of the regulatory support for the process of fire truck fleet management have been determined. METHODS. Using the method of graphical simulation, the dynamics of changes in the share of modern vehicles in the fire truck fleet has been described, considering the arrival of new samples. Analysing the available data, systemic problems related to the age and model composition of the fire truck fleet, which cannot be solved at the level of territorial bodies and institutions, have been identified. FINDINGS. The author of found that the share of fire trucks with the service life up to 10 years had decreased from 38.6 % to 24.1 % in the period from 2011 to 2021. Thus, if measures to replace aging vehicles from the fleet are not taken during the planned re-equipment, the share of these fire trucks in 2030 will be 34.3 %, which is below the level of 2011. But, if the authorities organise systematic work to replace aging fire trucks, that have no prospects for further use, the proportion of vehicles with the service life up to 10 years will reach 40.5 % by 2030. Proposals to improve the regulatory support for the process of fire truck fleet management aimed at optimizing its age composition have been developed. RESEARCH APPLICATION FIELD. The obtained results can be used in the practical activities of the governing bodies of EMERCOM of Russia and also in the development of legal acts regulating movable property replacement. CONCLUSIONS. The ways to develop the regulatory support for the fire truck fleet management process proposed in the article, which are based on the analysis of the fire truck fleet, are aimed at increasing the readiness of fire and rescue units to act as intended, and can be implemented by amending the current regulatory legal acts of EMERCOM of Russia regulating movable property management concerns.
