For private use? Hot take, but Arch. It’s easy to maintain and not easy to break at all. I think I spend zero time on maintenance other than running package updates. I only reinstall when I get a new computer.
(I say for private use only because you’ll be getting weird looks from people if you use arch on a server in a professional setting, and it might break if you try to update it after five years of not doing it since there aren’t any “releases” to group big changes - in practice I run arch on my home server too with no issues)
What kind of drones are these? Sounds like they’re consumed when used, are they basically missiles/rockets with better control?
