The Russian system encourages scale, but it also leads to widespread problems because one wrong component can affect an entire fleet of drones. And using just a few models repeatedly has enabled Ukraine to identify their vulnerabilities. JL
Sinead Baker reports in Business Insider:
Russia has focused on making bigger numbers of just a few models. While this has helped it produce them at scale, it also aids Ukrainian drone operators in identifying them and developing a sense of how to defeat them. "it's very easy to identify them. They rarely make any changes to the design." Russia's more centralized process (also) means that "if there's an error with a component part, then it will be an error that spreads across systems. If there's a loophole that allows you to hack, then it spreads across all systems and makes them vulnerable."
