@engineer,
I believe the matters now heading to Courts Martial will depend a great deal on the particular facts in each instance. This is appropriate as these are judicial proceedings and the rules of evidence apply.
With respect to maintaining accountability and addressing the underlying issues, the Navy summarily relieved the Commanding officers of each ship soon after each event. That's appropriate and beneficial, as the Captain's responsibility for maneuvering the ship and setting standards for the bridge teams is direct and beyond dispute. Not much later, after the preliminary results of as more widespread investigation, they relieved the Fleet Commander for a failure to establish and enforce training standards among deployed vessels.
I have since learned that the Navy is now focused on increased training effectiveness in basic areas such as these, and accepts that the long term decline in the number of operating ships, together with nearly fixed forward deployment loads led to a perhaps insidious lapse in basic training in some fundamental areas. There are three basic phases to any ship's operations - maintenance. training and forward deployment. The first is hard to compress, and, if the third is fixed, training time suffers: over time the effects are compounded.
