AN/SPY-1D(v) can detect and track over 100 targets in real-time in short order; it can develop Fire Solution(s) for many targets in the process. A single warship have limited magazine of-course but then multiple warships can be committed to a theater of operations and they are sensor-netted to each other (CEC) - this a topic in itself. Then there is the factor of how multiple warships can be positioned next to each other in order to complicate saturation attack options (military tactics in short). USN is competent in the EW regime in particular. USN seems to be very well equipped for a wide range of contingencies in the present, and it continues to evolve further at a rapid pace. While numerous Think Tanks were busy creating narratives for public consumption, USN was building formidable defenses without making much noise in the process. Now - suddenly - there are so many pointers on the web that these continue to surprise potential readers. WE need to be realistic in our expectations in this matter.It has probably intercepted single "stuff". When you have multiple DF-21D fired at aircraft carrier/warship? I doubt it would be able to intercept them all.
