Satellite images show Russia has built a dozen aircraft shelters at an airbase in Russia’s Volgorod Oblast. This came soon after Ukraine attacked the Russian airbase at Belbek, destroying or damaging several aircraft. Nothing changes a military organization faster than being shot at. As Ukraine develops (and receives) ever more means to strike Russian air bases far behind the frontline, Russia appears to be (finally) building shelters to protect its vulnerable jets. However, these may not be the hardened shelters many analysts think Russia should build.
