It is probably worth considering the implications if they did have limited capability low tech UAVs in large numbers - which could be readily mass produced so as to have swarms of the damn things. Even if they were only capable of hitting an aircraft carrier one time in ten and they launched a hundred or two in a swarm - not unfeasible - even the Aegis and CIWS would be maxed out would they not? And that could end in a real mess...
That low tech mass numbers approach can overwhelm modern swiss-watch solutions that the West so love, I wouldn't dismiss it too fast.
That 206 based helo could be a serious pest too if they had enough to swamp the defenses, and at the cost of those they could afford hundreds. Remember what fuzzy-wuzzies with asssegais did to the British Square on occasion. History leaves us a lesson there does it not?
