Missile interception technology like aegis relies on other ships detection and coordination with onboard defenses in an aegis fleet network.
Faster missiles mean a solution may be coordinated or countermeasure plotted too slowly to have any effect, or to arm things like CIWS countermeasures.
hypersonics, simply put, can sink US aircraft carriers before their protective fleet can take action, effectively neutralizing US presence in a region.

Hypersonic missions are slower than ballistic missiles. Their advantage isn’t speed per se, but in being able to fly under the horizon for longer. They’re also more manoeuvrable, though at those airspeeds you’re somewhat limited in this domain.
