I must be missing something it seems simpler to assume
"Coast guard gets report of lost sub and searches for a while".
Why would you turn that into
"USN knows that a sub imploded. Did nothing observable. Coast guard gets report of lost sub and searches for a while."
I looked at the link, I can't see any reason to interject into that more capability than was demonstrated. It may exist, it may not. There is no reason to comment on additional capabilities based on this event.
