Abstract

In response to escalating threats, NATO launched Operation Baltic Sentry, a coordinated effort to secure undersea communication and energy networks from sabotage and cyber-attacks. This paper examines the strategic importance of the Baltic Sea, the evolving nature of hybrid warfare, and the core components of the Baltic Sentry initiative. It explores the role of naval assets, surveillance technologies, and multinational cooperation in countering emerging threats. Additionally, the study evaluates the mission’s implications for regional security and NATO’s long-term strategic posture. While Baltic Sentry marks a crucial step in securing vital infrastructure, challenges such as resource limitations and the complexity of hybrid threats necessitate ongoing adaptation. The operation underscores the need for enhanced intelligence-sharing, advanced surveillance systems, and sustained multinational collaboration to safeguard stability in the region.
