As I stated earlier in this thread, the salvos (assuming a truthful statement) answers one of the questions - that the payload or warhead itself is not sufficient for a one-shot/one-kill. Granted, a near or non-fatal hit can invoke a mission kill. The other implication is that they have enough confidence in their sensor capability to track for multiple firing attempts. Again, if true, that's pretty significant. The question mark remains about OTH targeting, this isn't an LOS weapon, and not only finding and fixing, but tracking via OTH is a complex technical capability that not many nations have.A pseudonymous article posted on Xinhuanet, website of China's official news agency, imagines the U.S. dispatching the George Washington to aid Taiwan against a Chinese attack.
The Chinese would respond with three salvos of DF 21D, the first of which would pierce the hull, start fires and shut down flight operations, the article says. The second would knock out its engines and be accompanied by air attacks. The third wave, the article says, would "send the George Washington to the bottom of the ocean."
