Defense Express reports.According to the Main Intelligence Directorate, the flight range of the Geran-2 is 1,800–2,500 km. This means that from their current positions—in the Bryansk region, occupied Crimea, or St. Petersburg—the Russians can attack Scandinavia, the Netherlands, most of Germany, and southern Italy. At its maximum operational radius, the strike range also covers all of Great Britain, France, and Italy."But it should be recalled that deploying new launch sites for drones takes Russia only a few months. Therefore, if necessary, they can indeed be deployed very quickly (if the Russians haven't already done so), for example, at the Vosaŭcy airbase in the Brest region of Belarus. The possibility of launches from the Kaliningrad region should also not be ruled out," emphasized Defense Express.Experts stressed that technically this gives Russia an additional 700 km advantage. Consequently, if the Russian Shaheds have a flight range of up to 2,500 km, almost all of Europe would be in the strike zone, including half of Spain's territory and Madrid. That is, all European capitals except for Lisbon, Portugal.At the same time, Defense Express noted that despite the 2500 km flight range, Russia launches drones on complex routes to bypass air defense systems. However, the incident with Shaheds in Poland revealed gaps in the air defense of NATO's eastern flank.Russia is likely counting on the fact that after breaking through the first line of air defense at the border, the drones will be able to move relatively freely, aware that the means of destroying such drones in Europe remain significantly more expensive than the Shaheds themselves.Russian drones in Polish airspace.
