The attack sub USS Connecticut, involved in an underwater collision in the South China Sea... 20

If you measure those tetrapods, you can see that each one is about the size of a small car, and as a concrete barrier, they're taller than a tank can climb and weigh about one-half a main battle tank

Not sure those flowerplanters would do in this case.
This where the old obstacles they where no match for a truck.
The large lions consist of five parts and weigh four tons.
The base measures 120 times 240 centimeters and the lion has a height of one meter.
The small lion weighs about 900 kilos.

And this the new ones

From the news...

"The US Navy has fired a nuclear submarine's Commanding Officer, Executive Officer and Chief of the Boat for 'loss of confidence' after their vessel collided with an 'uncharted seamount' in the South China Sea.

The $3.1 billion USS Connecticut's CO Cmdr Cameron Aljilani, XO Lt Cmdr Patrick Cashin and COB Cory Rodgers were relieved of their positions on Wednesday."

I didn't know they had a 'Chief of the Boat' position.

Chief of the Boat; Is the most experienced enlisted member of the crew, often the most experienced person on board.

Fired three guys?

That implies they made a big mistake. And it's hard to see how hitting the unseeable could be classified as a big mistake.

We have this:

“determined [that] sound judgment, prudent decision-making, and adherence to required procedures in navigation planning, watch team execution and risk management could have prevented the incident,”

Looks like the navy thinks it WAS seeable!

In the Navy, no matter what occurs, it's automatically the responsibility of the Captain. A ship running aground can cost a Captain his command, even if he was off duty and asleep in his cabin. As for the Executive Officer and Chief of the Boat, I would suspect that there's more to this than a simple mistake.

Thanks... didn't know the term. Unless he was involved in the operation, it seems odd to 'fire' (fire - dishonourable discharge?) him. It's not a good way to end a career.

There's a lot of dead-reckoning involved and probably a ton of cross correlations. I can see them missing one bit of data and deciding to press on resulting in more of a press-in-to.

I was a sub engineer and was at a shipyard. A different sub came into the dock and tied up. A car pulled up and a few guys in uniform stepped out. A few guys from the boat climbed up the ramp and the two groups met and had words, saluted, shook hands, etc. The guys from the car went on the boat, the guys from the boat got in the car. The car left.

Found out later that it was a change of command. Something happened on that boat (I don't know what it was) and the fleet command "lost confidence".

The US Navy takes this stuff seriously. Something bad happens on your boat and the captain (certainly) and anyone else even remotely responsible is going to lose their job. Usually not kicked out of the Navy, but you will "drive a desk" and get zero promotion until you quit or retire. Career ending. No debate. No arguing. Done.

I know about 'lost confidence'. During the last war (WWII), my dad, for part of it was a wireless airgunner, and was acting as a navigator on one flight. The pilot asked him a question and questioned my dad's response with, "Are you sure?". They had been flying together for months (weeks?). My dad lost confidence in the pilot and asked to be transferred. On the pilot's next flight, he was killed.

Yes, when it comes to the military, being 'fired' does not necessarily mean that you're being discharged, just that you're being removed, involuntarily, from your current position of responsibility. Now if the incident warrants it, an officer or enlisted person could also be subject to a court-martial, which again may or may not result in them being discharged from the service.

Also note that the removal of the senior officers and enlisted personnel could be part of the process needed to conduct a fair and unbiased investigation of the incident. It's very possible that if it's deemed an unavoidable 'accident' and that nothing could have been done to have avoided it, those individuals may be allowed to hold future positions of responsibility but certainly NOT back on the USS Connecticut. However, there will be a notation of the incident in their permanent record and even if they've been fully exonerated, it will very likely follow them around like a shadow that rest of their career.

Here is an hour-long discussion about US military commanders getting "fired":

That was a good talk. Listened to the whole thing.

 

[Comcokid]

The USS San Francisco in 2005 while cruising in a part of the ocean where the bottom was far deeper than the crush depth of the submarine ran into an uncharted seamount rising thousands of feet from the bottom. The main navigation charts did not show any hazards. But other supplemental charts showed "dark waters" within ten miles of where the accident occurred. (I'm not familiar with the full meaning of this term, but read this a month ago in a article I cannot find now.) Several including the captain were held responsible anyway as there was this secondary reference chart somewhere onboard that implied they may be near an unknown hazard. Captain is always responsible.

What I find interesting about the USS Connecticut incident is the South China Seas are generally much shallower, are extremely well traveled, and hence very well charted. It's not like the remote parts of the Indian Ocean that were charted for the MH370 search. That part of the Indian is not traveled much, and the major features they did find were very, very deep - still below 5,000 feet at the highest.

Why would anyone drive a submarine into waters that had any degree of uncertainty in the bytyhmetry, UNLESS they were hunting or being chased by something much more dangerous? Or was it a newly formed seamount that nobody Kew existed?

 

[spsalso]

Well, there's snooping and skulking.

The term "bathymetry" originally referred to the ocean's depth relative to sea level, although it has come to mean “submarine topography,” or the depths and shapes of underwater terrain.

In the same way that topographic maps represent the three-dimensional features (or relief) of overland terrain, bathymetric maps illustrate the land that lies underwater. Variations in sea-floor relief may be depicted by color and contour lines called depth contours or isobaths.

Bathymetry is the foundation of the science of hydrography, which measures the physical features of a water body. Hydrography includes not only bathymetry, but also the shape and features of the shoreline; the characteristics of tides, currents, and waves; and the physical and chemical properties of the water itself.

I suspect that considering the current state-of-the-art in mapping the sea bed, if you had to limit yourself to only those areas where you had overwhelming confidence that your 'charts' showed EVERYTHING that could cause harm to a sub, you'd be limited to a rather small number of areas of operations.
