Regardless of other problems, TFA makes it clear that LTJG Coppock failed really hard between 0120 and 0130. Although her subordinates probably should have detected the Crystal sooner, she had ten minutes to save the lives of her crew, and she should have done so. Navigating out of danger might not have been possible, but an emergency stop like that executed by LTJG Breau a month earlier would have worked. The really unforgivable (as in, detail a firing squad) offense was not to sound the alarm and get those sailors out of their soon-to-flood bunks.
I'd say that the captain should receive the same punishment that Coppock gets, and the captain of a month before as well. It's difficult to say from the outside whether that should go up the chain, but perhaps it should, just to be safe.
