Kaliningrad is often called Russia’s Baltic fortress, and it is armed like one, with Iskander-M missiles, layered air defence, the Baltic Fleet’s and at least one suspected site for storing nuclear warheads.
Together these let Moscow threaten the Suwałki Gap and NATO’s sea and air routes into the Baltic states. Yet the exclave is also exposed. It depends on transit through Lithuania, on flights over the Baltic and on gas brought in by ship. Every closed crossing or sanctions dispute therefore becomes a test of strength.
Its value to Moscow is less as a fortress than as a tool for steady, deniable pressure. GPS jamming traced to Kaliningrad has disrupted Baltic aviation since 2022. Russian aircraft briefly entered Lithuanian airspace in October 2025. A draft decree redrawing Russia’s sea borders appeared, and was withdrawn, in a single day in May 2024. The question is not whether such probing continues, but where its threshold lies.

We have created a series of maps of Belarus and Russia’s northwestern regions. We call them Pressure Points as they represent a showcase of military installations, energy facilities, economic powerhouses and environmental vulnerabilities along northeastern frontiers of EU & NATO countries. All used data come from open sources.
