Just wondering why you find that interesting...Seriously, I know little about Navy protocol, etc...so just wondering if you could explain :)
Generally, if I remember correctly, the buck usually stopped at the ship’s Captain. This time, they jumped up a couple of steps in the Chain of command and fired the Fleet commander. It indicates to me a perception that this is systemic, not individual ship failures.
I am a retired Army officer, most General and Flag Officer reliefs of which I am aware involve personal misconduct (adultery, financial irregularities, etc...). This is a firing for an operational failure, something that has been very rare over the recent past.
