Russian troops have begun constructing defensive structures at some of their airbases following the Security Service of Ukraine's Operation "Spiderweb."

Satellite imagery obtained by the Ukrainian organization Frontelligence Insight on July 7 shows that at the "Khalino" airbase in Russia’s Kursk region, Russian forces have built around 10 fortified bunkers covered with layers of soil, 12 concrete bunker-type structures without soil cover, and eight hangar-like buildings located on the tarmac.
