Do you think China isn’t watching as Ruzzia gets demilitarized?
A drone costing a couple thousand dollars disables a multi-million-dollar bomber. Yeah, they can keep it up until the Muskovites figure out a defense. Not easy, since the drones can be 100% internally guided. No control signals to jam.
The drone attacks have already forced a couple of relocations of RuAF aircaft and operations to bases further away. This one will push them away some more. That matters vs the effectiveness of cruise missile attacks, as it adds detection range and warning time for cruise missile sorties.
