The article examines the synergistic effect of strengthening the state's defense capability and military power, and improving the effectiveness of social policy and social security in Ukraine. The use of multi-criteria analysis of integral indices, such as the Security Threats Index, the Refugee and Displaced Persons Index, and the Comprehensive National Power Index, along with formulas for calculating state power, allows for the tracing of the impact of war on social components, the development of social security, the institutionalization of social protection systems, and the creation of ministries of national welfare to overcome the socio-economic consequences of war. The author identifies the Ukrainian model of state functioning in wartime as a symbiosis, combining effective social protection policies and strengthening military power through systematic support for the army: "strong home front – strong army." War significantly transforms social protection and social security policies, necessitating state intervention to support citizens during and after military conflicts. This intervention takes the form of social welfare in the form of benefits and subsidies, free education and healthcare for the poor, due to the high probability of losing jobs, homes, or even lives. The author emphasizes that the global socio-economic system is adapting to the turbulent environment of the BANI and TUNA worlds, where new types of risks are difficult to control and their consequences are unpredictable. The large-scale war by Russia against sovereign Ukraine has revealed instability in the world order and demonstrated the need to develop a Ukrainian model of a "welfare state in war" with a focus on strengthening the military component. To achieve the main goals of Ukraine's modern national security policy—ensuring the security of individuals, society, and the state, preserving independence, territorial integrity, sovereignty, and further progressive development—political consolidation of citizens around common values and interests, preservation of civil peace, overcoming existing political contradictions, and achieving a socially acceptable standard of living are crucial. This can be achieved by maintaining a balance of interests among all objects of national security protection.The article examines the synergistic effect of strengthening the state's defense capability and military power, and improving the effectiveness of social policy and social security in Ukraine.
