Hmm, I feel like you get back to "Ukraine needs everything it can get". Sure, but that's not my point. For your wide area monitoring, you don't want your radio to be jammed because it makes it useless. So if you think about building your equipment, you'd rather build jamming-resistant radios, right? > I argue that you can in fact have a civilian drone manufacturing which can be repurposed quickly It could potentially be repurposed relatively quickly if it was well designed. But what tells you it will be? Most software is not very well designed, and in the western drone industry it's particularly right, in my experience. If you subsidise a company to make military drones and they write bad software, you will still end up with a military drone ("the software is bad but it lasts 25min most of the time"). If you subsidise a company to make survey drones in the hope that their design will be good enough to be quickly ported to military needs... > both sides use civilian service for video streaming and communication which works better than anything "military grade". I highly doubt that. Civilian radios are easily jammed. |

In practice, jamming of wide area is not a solved problem. It is easy to jam GPS because its signal is already weak, or a cell phone in a city, but it is very difficult to jam a drone in the sky which have a line-of sight to the antenna or a retranslation drone. Also all modern cheap drones have a way to switch frequencies if one gets jammed, and jamming all frequencies is also very very difficult.
You either need to have a very big powerful machinery - which is very easy to detect location of and send a HIMARS rocket. Or a huge number of smaller devices, which is impractical as you don't have power in trenches.
So in practice, drone jamming is only effective in the last 100-200 meters from the target (if it is a vehicle with power source) which doesn't really matters for surveillance drones as they do their job from the distance.
> Civilian radios are easily jammed.
In theory, in practice on the battlefield, when drones can switch frequencies on the go - very very difficult with the exception of the last hundred meters.
Because of this, modern killer drones now have a primitive "AI" to lock on the target on the last meters of approach.
