On the topic of small quadcopter UAVs which has come up occasionally over the years, this article is a good summation for why the effect of small UAVs may be ultimately finite in context of a proper air/missile/naval war.
It is high end capabilities (strike aircraft, bombers, high end UCAVs) which permit or deny the other lower end capabilities (including low end small UAVs like quadcopters and the like) to fight and sustain themselves.
It is rare for small UAVs and quadcopters to be able to properly reach out at range to destroy an enemy, including even "long range suicide drones" as they are low performance, slow and may be easily countered by even a marginally competent air defense force.
This is important when people discuss "Chinese UAV production capability" because while China is far and away the leading producer of quad copters and small UAVs and potentially also small suicide drones, their relevance in a high end air-naval-missile fight is limited.
Instead, for a high end fight, it is proper fighters, bombers, high end UCAVs/UAVs, and long range missiles and associated high end sensor platforms which will be much more decisive.
