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 bombers were a bonus. Ukraine was targeting the unfueled Kh-22/X-22 missiles that were openly stored at the airbase. The smoke is from the missiles that were destroyed.
You know I think you miss something , Russia has been using low text stuff to take out both drones and military jets by the simple expedient of dumpling Jet fuel on them. It’s not hard to design some kind of Counter measure to take out the cameras of the drones via oily residue and electronic jamming. Or maybe Russia will make good on it’s threats and take out the GPS satellites which the drones depend.
I’m not sure you can make a substantial drone (range, payload) with what amounts to a form of AI guidance for a couple thousand bucks. A quite good friend of mine who did work on exactly this sort of guidance, relying on DSP chips fed imagery data (visual, infrared, radar) has his doubts, but concedes that commercial grade electronics, as opposed to mil spec, would get the job done more often than not.
In any event, if the propulsion is relatively quiet, low, slow drones are nearly impossible to spot acoustically or with radar, and as you say, no control or GPS signals to jam. Very tough to stop until they are “on” you.
BTW, I should add that my friend did this work for several years back in the ‘90’s. The advances since are quite substantial.
