“It was not the captains fault. The dang mountain wasnt mapped. No one knew it was there until the sub hit it.”
But they mapped the Ocean floor already? Is it possible the mountain rose up from the floor since the mapping?
I can’t answer you question because I don’t know.
There are a couple of ex navy folks on this thread that can help.
Thank you for asking though.
This is one of the responsibilities of command. The navigation team failed, and the CO, or XO should have caught it.
