The article examines problematic issues of the functioning of defense procurement and their impact on the state’s defense capability.The issue of improving the current norms of the Law of Ukraine «On Defense Procurement» was considered. It was emphasized that in the conditions of a full-scale invasion of the Russian Federation on the territory of Ukraine, the prompt adjustment of state policy in the field of providing for the Armed Forces of Ukraine and other components of the security and defense forcesdepends on the quality of the current legislation of Ukraine.In domestic science and practice, the issue of defense procurement is new and insufficiently studied, since the relevant legislative act, which regulates the specified sphere, – the Law of Ukraine “On Defense Procurement” – de jure entered into force only on January 1, 2021, and de facto – partially began to be applied from January 1, 2022, since with the beginning of the full-scale invasionof the russian federation on the territory of Ukraine, procurement procedures, stipulated by the specified legal document, were not applied.Inadequate and/or low-quality legislation in the field of defense procurement leads to a decrease in the effectiveness of the security and defense sector in performing its functional duties, and therefore decreases the level of the state’s defense capability. The full-scale invasion of the Russian Federation on the territory of Ukraine requires prompt adjustment of state policy in the field of logistical support of the Ministry of Defense of Ukraine, the Armed Forces of Ukraine, territorial defense forces in their composition, theSecurity Service of Ukraine, other subjects of the security and defense sector, the introduction of non-standard approaches to the introduction of the latest technologies with the aim of increasing the capacities of these structures. In this regard, legislation in this area should be immaculate and meet modern requirements.
