Electronic warfare in the Baltic Sea is escalating rapidly, with GPS and AIS disruptions posing growing risks to maritime navigation. Russia’s hybrid strategy is targeting both safety and stability in one of Europe’s most critical shipping regions. Pilots and crews now face a new reality: navigating under threat.
