Russia is significantly increasing its military presence along its western border, particularly in areas adjacent to Finland. This initiative includes refurbishing aging military bases in places like Petrozavodsk and Kantalahti, according to Finnish Defence Forces' military intelligence. The developments are seen as a reaction to Finland's accession to NATO, with predictions indicating that Russian troop numbers in the vicinity could rise from 40,000 to 85,000 by the 2030s. This gradual build-up of military capabilities raises concerns regarding regional security and the potential implications for Finland and NATO partners.

The assessments from military experts, including Juha Kukkola, an adjunct military professor at the National Defence University, suggest that while the changes are proceeding steadily, Russia’s capacity for military operations in the area will significantly improve after the conclusion of the war in Ukraine. This increasing military readiness by Russia is not only a display of strength but also a strategic maneuver to counter NATO's expansion in the region. The Finnish Defence Forces have highlighted these developments in their recent public outlook for 2026, signaling a readiness to address the evolving threat landscape.

Recent satellite imagery published by Yle indicates that renovation work has commenced at the former military base in Petrozavodsk, with local media reporting plans for new military construction projects in the region. This foreshadows a potential shift in military dynamics in the area, necessitating vigilance and preparedness from Finland and its allies. As such, the growing militarization of the Russian border raises a series of geopolitical questions regarding the future stability of Nordic countries and the security policies of NATO.
