The pension system is an important area that ensures the stability of any society. In the conditions of a full-scale invasion of russia into Ukraine, in accordance with the essence of the solidarity pension system, there is an increase in deep disparities between the available number of persons who need pension protection and persons who have to form this protection with their contributions. The aim of the research is to evaluate the pension system of Ukraine under the conditions of martial law and to substantiate the directions for its improvement. The hypothesis was tested that the level of financial stability of the pension system affects the countryʼs ability to maintain social justice and the effectiveness of state regulation of human potential. In this research it was used a systematic and logical approach; method of theoretical generalization, comparison, analysis and synthesis, scientific abstraction. A feature of the pension system in Ukraine is the functioning of the first and third levels of the system, while the second is in a state of reform (does not work). The foundation of pension protection is the solidarity pension system, which suffered the most negative impact from the military operations on the territory of Ukraine. It is substantiated that today the Ukrainian and European pension systems have similar problems, which allows us to generalize the acquired experience and use advanced measures to improve the pension protection of Ukrainian citizens. Given the factors of the pension fund deficit and existing disproportions between the working population and pensioners, the following main approaches to the development of pension provision in Ukraine are proposed, such as comprehensive support for the development of non-state pension funds, the introduction of accumulative pension insurance; taking into account the European experience – the formation of an additional fund to the Pension Fund of Ukraine (PFU) to ensure a fair pension in the future. It is assumed that the use of European experience in the process of pension reform, taking into account the state of war in the country (which has no time frame for ending) will make it possible to harmonize the existing stratification between the working population and pensioners
