@bruces there's also that rapid feedback loop on your own design. If it doesn't work it's no longer a WWII "let's look at damage on returning weapons and strengthen the other bits" its "let's look on youtube to see what went wrong", as different teams along the front compete for the likes, brand recognition and the donation of new drones.
Then there's the detail that both sides use the same LEO satellite constellation operated by the world's first trillionaire for this CI/CD feedback loop.
