Come on they are ashm do you really think they would have a chance of launching this against PLAN ships? These missiles will be taken out in the first few hours of conflict.Quantity has its own quality. Yes they are "old" tech. But they are still missiles. They can still hit a ship and sink it. And its not like the PLAN has unlimited magazine depth to intercept them.
The more these systems are introduced, the more complex a military conflict will be.
Yes PLAN would most likely be ok, but thats another thing they have to worry about. We will see what other systems the US is planning to sell Taiwan
