I have heard they are building these on their own. Might be a cover story, but on the other hand I have seen software development in both highly bureaucratic organizations and free situations and can tell that a couple of boy geniuses whipping together a software that is almost as good as what military paid many millions for is very plausible. Then you will just need a toy chopper and fit it with an iPhone running your custom software.
Could be. Ukraine is pretty far along, in some areas of tech. They just have not put it into their own military in a widespread way, in the past.
