US Nuclear Sub Crashes Into US Navy Amphibious Vessel

Kugrian writes "Showing that it's not just the British and the French who have trouble seeing each other on the high seas, a US Nuclear submarine yesterday crashed into a US Navy heavy cruiser. The USS Hartford, a nuclear-powered attack submarine, was submerged as it crashed into the USS New Orleans in the strait of Hormuz, resulting in the spillage of 95,000 litres of diesel fuel. Both vessels were heading in the same direction when the collision occurred in the narrow strait and were subsequently heading to port for repairs. A spokesman for the 5th Fleet said that the USS Hartford suffered no damage to its nuclear propulsion system." According to the USS New Orleans' Wikipedia page, it's actually an amphibious transport dock.

I'm an ex-submariner who served with some of the guys on the Hartford (not my boat, but I went to school with them). This kind of thing is extremely unfortunate, and it really sucks for the whole community when accidents like this happen. I was relieved to find out that nobody was killed, and my thoughts are with the crew as they deal with this mess.

Yes, this is the result of human failure. That's not up for debate, and I'm not trying to excuse the mistakes that led up to this event. I'm trying to reinforce the idea that this kind of work is inherently dangerous, and that the men who serve on these vessels accept a lot of risk to do their jobs. Please consider this before launching an overly heated reply. Thank you.

The USS New Orleans isn't equipped with a sonar suite, perfecting underwater stealth technology sufficiently to hide from her isn't much of an accomplishment.

I believe that's fake, or at least drawn out since the dawn of time. http://www.snopes.com/military/lighthouse.asp Still amusing I guess.

I'll be happy to help with your answers, to the extent that I'm permitted. I hope you understand that there are things Sailors can't talk about, and my statements in no way reflect the official position of the U.S. Navy on any matter related to fleet operations. I'm not even in the Navy anymore, but I just got out at the beginning of March, so I'm still pretty close to a lot of folks who are serving.

Now that we're done with the disclaimer, here's what I can say about your questions:

1. Ultimately, the CO is responsible for anything the vessel does. This is a big job, and involves years of training and study. Typically, submarine COs are Commanders or Captains. Down the line, the Navigator is indeed accountable for the vessel's movement. However, the Navigator depends on accurate input from multiple departments in making real-time decisions. Small mistakes in any area can result in large problems. This stuff is hard work, and inherently dangerous.
2. Yes and no. Depends on what ships we're talking about, but the answer is mostly no in the vast majority of cases. Submarines are built for stealth, an attribute they excel at most of the time (people get in trouble when that's not the case). This puts big limitations on what subs can do to keep tabs on their environment, however.
3. There's a big difference in knowing that something's out there, and knowing precisely where that vessel is. It's an imperfect science that depends heavily on rapid analysis of a whole lot of variables at once, and operating conditions and mission requirements sometimes make it necessary to operate in close proximity to other vessels. It's just part of the job, and 99.9% of the time there are no problems. Factors like sea state, water temperatures, and other considerations can make the job of monitoring proximity more difficult. Seafaring civilians understand a lot these issues, too.

I hope these answers help give you an appreciation of the complexity of these operations. My initial reply was intended to get you to stop and think; sorry if I came across too hot. Thanks for your interest.

Since you obviously know the subject, maybe you can comment on three items of my post:

1. Who has the primary duty to avoid such a collision?

Both parties, actually. But the Sub will be held to a higher standard. Because the surface ship is expected to not see the boat.

2. Is it reasonable to expect a surface ship to see a submarine 30' below the surface at night?

30' below the surface isn't nearly far enough down to make the sub invisible, even at night. But, in general, we don't expect surface ships to see our subs unless they're snorkeling.

3. Would it be expected that many sailors aboard the sub will hear 100,000 HP diesels of a surface ship a couple of hundred feet away?

Two things:

New Orleans only has 40,000 HP engines.

The anechoic coating on a submarine makes it pretty hard to hear anything going on inside from the outside, and pretty hard to hear anything going on outside from the inside.

On the other hand, we usually expect the sonar guys to hear this sort of thing.

On the gripping hand, you won't be trailing your tail in the Straits of Hormuz, and aren't likely to hear something overhauling you until it gets really close. By which time dodging is impossible in restricted waters.

In my opinion these answers, made by a competent person, would be far more useful than guessing about me and at the same time telling nothing on the subject of discussion.

Probably. The real question in the business is who was overhauling, and who was being overhauled. There's no excuse for a sub bumping a diesel-powered LPD from behind. There's a lot more excuse for the boat being run over by the LPD in tight waters, which these were.

I should note that the last couple paragraphs of TFA were completely unnecessary, and serve no other purpose other than to contribute to anti-nuclear hysteria - the presence or absence of nuclear weapons had no effect on the collision between the French and Brit boats, and there was ZERO chance, even if both boats had been sunk by the collision (basically impossible unless both boats were running at flank speed, and damn unlikely even then), of any of the nuclear weapons on board being a "catastrophe narrowly averted".
