Satellite imagery analyzed by Finnish media outlet Yle.fi reveals that Russia is actively upgrading military infrastructure near its border with Finland to accommodate a 15,000-strong army corps. According to reports, construction has advanced at a base in Petrozavodsk, located approximately 160 kilometers from the border, where forests have been cleared and heavy transport vehicles are now deployed.
Satellite Imagery Reveals Petrozavodsk Base Expansion
Recent satellite photographs show distinct construction progress at the Petrozavodsk military installation over the past several months. According to Yle.fi, land was cleared in forested areas near the base as early as spring 2025. Numerous military trucks and transport vehicles are currently visible throughout the site, signaling active logistical staging.
Assessing Regional Troop Levels and Mechanized Support
Current Finnish defense estimates place the number of active Russian military personnel in the Republic of Karelia at between 2,500 and 3,000 troops. According to available reporting, the majority of this existing personnel consists of air force staff operating out of local aviation facilities.
However, Finnish military expert Marko Eklund notes that the influx of heavy transport trucks points directly to the deployment of a mechanized brigade. This unit is expected to provide logistics and operational support for the newly planned army corps.
Did you know? Petrozavodsk sits just 160 kilometers (about 100 miles) from the Finnish border, making its logistics hubs critical for regional troop movements in Russia’s northwestern military district.
Future Outlook for the Finnish-Russian Border Garrison
According to Marko Eklund, “Currently, there are no indications of combat units entering the region, but most likely the Petrozavodsk garrison—currently undergoing reconstruction—will be utilized by the new army corps.”
