As I noted above, a nuclear submarine can move fairly quickly (15+ kts) unhampered by high seas on the surface. And they are already equipped with a sonar suite of great power.(even one as old as the Tireless).

It's possible the US would be hesitant to use our subs in the area where the Chinese are searching for the wreckage using ASW planes. That could let the Chinese learn some things we don't want them to know if they get a track on one of our boats.
