"Who are we hiding from?"
You can't hide a nuke sub that is doing 30 kts. Subs do not run silent at that speed. So why no active sonar? A very good question. Next question: At 30 kts, would active sonar have given them warning soon enough to avoid the "mountain"?
Well, that's a very good question, too. And I wish I knew.
I understand how the Navy has to make someone responsible for such accidents, but it sure seems a shame that one man takes all the blame. I'd like to know more details about his access to accurate, up-to-date charts, or maps (or whatever the Navy calls them).
I just hope the man isn't taking all the blame if some of that blame should go to any of his higher-ups. He doesn't lose his retirement benefits, does he? I haven't been keeping up with this very well.
