The best method to send pacom/USN aircraft carriers to the bottom of the sea is the well-tried-and-tested method employed by russia and iran during combat in recent times.
What's that.
A sustained attacking combo of drones and missiles.
The giant aircraft carriers have NO WAY to retreat from their fight at high speed.
Thus, in the coming 'high-end clash' or 'high-end dustup' china must ensure it has the numbers. Numbers concerning the amount of drones and missiles required to finish off all the sea monsters.
Amen.
