What about drones as well? Doesn’t what is happening in the Black Sea suggest that anything above water is an easy target?
Taiwan troops fire on Chinese drone intruding over outer island for 1st time
Not necessarily true. What you could do is have a lot of cheap drones that don’t do much but attract fire swarm the invasion fleet and have the invasion fleet expend missiles and ammunition against the cheap drones - a form of drone chaff. You also send in more capable drones and hit smaller ships with bombs to damage and disable them. For the larger ships you can send the subs.
Well, I suppose if you have 1000 armed drones to throw at them it might make a difference. But I suspect the Taiwainese do not.
