Layerd and networked defense,you don't want to target lone single ship but battle groups
@undertakerwwefan and supersonic one has lot earlier to detect track,beyond 50 km by ship sensors,main threat for USN is sizziler type of anti ship missiles with subsonic. at cruise phase and terminal supersonic dash at cruise phase they have very low IR and radar RCS hence difficult to detect,track and engage at cruise phase and at terminal they have less reaction time than all subsonic anti ship missiles
