Soviet surveillance drones, which Ukraine has used a few times as suicide drones, were not much more complex than a radiola. Had a flight program in the form of perforated tin disc, if I remember correctly, and an electro-mechanical system of following those instructions (not a computer). They’d be just sent on preprogrammed routes, make photos, those retrieved and analyzed on return. No radio communications, stealthy enough for their purpose.
That and also - humans not knowing something can man up and learn it. When they need, they’ll learn.
And OP’s question about European clouds - it depends really. A lot of what this endeavor needs is just advanced use of OpenStack. I’m confident there are plenty of people with such skills in the EU countries.
As for the post content - I dunno, my experience with Kubernetes consists of using it, but not trying to understand or touch it too closely, because it stinks. Maybe those engineers were like that too.
