While it is known that the DF-21 “aircraft carrier killer” — which Tsai said was also recently deployed — has multiple warheads, news that smaller missiles in the Chinese arsenal have multiple reentry vehicles (MRVs) would be a worrying development, Fisher said.
“PAC-3s can only handle one incoming missile target, not [several] MRVs,” he said, adding that the US had recently canceled a missile defense program intended to give missile interceptors the ability to take out MRVs.
