The standard response to "hypersonic missiles are making surface ships like this obsolete" is that kill chains [0] are long and difficult. Of course, submarines, distribute sensors (like radars on man-made islands), and satellites help a lot, but they're also all vulnerable: subs are slow and might not be in the right position, and islands and satellites are relatively easy to target. Regardless of whether or not the kill chain is vulnerable, you still have to actually launch the missile or plane carrying the bomb. Ships are still the best way to do this, so it's going to take extremely effective antiship systems to make it not worth it. [0] A kill chain is the processes and systems a weapon needs to actually hit a target. It includes detecting a target in the first place, making sure you actually have a launcher within range, tracking the target while the missile is on the way, and actually impacting the target at the end.
