## Situation Report
Construction of aviation hangars and protective shelters is underway at the Petrozavodsk airport in Karelia, according to satellite images (Intel Slava). The hangars and shelters are reportedly intended for the Su-27, Su-30SM, Su-35S, and Su-57 aircraft.
## Strategic Context
The Petrozavodsk airport is located in the northwestern region of Russia, near the border with Finland and Estonia. The region has seen increased military activity in recent years, with Russia's Northern Fleet conducting exercises in the area. The construction of the hangars and shelters suggests an effort to enhance Russia's military presence in the region.
## Geopolitical Implications
The construction of the hangars and shelters at Petrozavodsk airport may be a response to NATO's increased military presence in the Baltic region. The move could be seen as an effort to counterbalance NATO's military capabilities and demonstrate Russia's commitment to defending its interests in the region. The development may also have implications for the ongoing conflict in Ukraine, where Russia has been accused of using Su-27 and Su-30SM aircraft to support its military operations.
