This paper examines how Ukraine, despite its inherent technological and numerical disadvantages, successfully denied its opponent control of the sea in the ongoing Russo-Ukraine war by employing innovative contemporary technologies and asymmetric strategies in the naval domain. To develop a deeper understanding of the successful usage of these asymmetric strategies a qualitative case study will be conducted using Milan Vego's theory of Sea denial. Vego ́s theory provides a framework to structure the analysis and understand how these strategies have disputed Russian sea control throughout the conflict. The result of this paper shows how Ukraine has avoided concentrated attacks, instead favouring sporadic, small-scale offensive actions through asymmetric methods. This approach has enabled Ukraine to be strategically defensive while allowing unpredictable operational and tactical offensive actions across the entire area of operations. The findings also illustrate how Ukraine has continuously adapted these methods throughout the conflict and highlight how asymmetric naval warfare can be a powerful tool for an inferior state to counter numerical and technological superiority.
