Hostilities in eastern Ukraine have highlighted the need for accelerated transformation of Ukrainian armed forces and strengthening country’s defense capabilities. Ukraine is an active consumer and exporter of weapons, so it needs to improve constantly its position in the international arms market, which, by the way, unlike most markets suffering from the COVID-19 pandemic, is constantly growing. The study aims to assess the prospects of Ukraine’s integration into the world arms market to secure its armed forces and achieve the highest possible level of arms exports. Methods of comparative analysis and integrated approach were used in the study. The obtained results demonstrated that Ukrainian arms export has fallen dramatically in recent years (from 1501 million USD in 2012 to 115 million USD in 2020); the largest importers were China (36% of Ukraine’s total arms exports), Russia (20%), and Thailand (17%). The main explanation for this is the necessity of transition to more technological weapons. Concerning weapon imports, Turkey, the USA, Great Britain, Poland, and Bulgaria became the main suppliers. It is about ammunition, electronics, including electronic warfare stations, means of communication, sniper rifles, grenade launchers, etc. The study substantiated that Ukraine should implement joint projects with other countries to fully develop its high-tech weapons in accordance with the latest military technologies.
