This is the first I have heard of this, what caused it to run aground?

Lewis Tanner 01-27-05 04:58 PM

Anyone want to venture a guess on the estimate?

:eek:

Uncharted rock formation + 30 knots underwater = more than Maaco could handle.

My bet is the were performing some sort of "silent dash" excercise which relied upon charts rather than active monitoring of the seabed.

PeteRR 01-27-05 05:01 PM

She hit a previously uncharted obstruction:

on January 7, 2005, the USS San Francisco, while on its way to making a routine port visit to Brisbane, Australia, ran aground and hit the ocean floor, approximately 350 nautical miles(560 kilometers) south of Guam, in the middle of the East Marianas Basin. The incident reportedly caused one critical injury and a number of minor ones to 23 of the submarine's crew ranging from broken bones, lacerations, bruises to a back injury. The critically wounded sailor later died of his injuries. Initial reports indicated that the submarine's hull was intact and that the submarine's nuclear reactor plant had not been damaged. The submarine resurfaced following the accident and proceeded to return to its homeport of Guam.

The article I read (I'll look for it) said exactly that.

I was wondering when images would come out on it... That's insane.

Brian Robertson 01-27-05 05:25 PM

My question is, how the hell is there any "uncharted" ocean left? It isn't like the Pacific is "Darkest Africa" or anything...You would have figured by now that our maps would be relatively accurate.

Tob 01-27-05 05:27 PM

Lower right hand corner (high res).

The 'job built' ladder got us a hefty fine from OSHA. Doesn't appear to be vertical supports under each 2X4 rung. I doubt the OSHA morons would get very far with the military (exempt, I assume). But they love to $crackdown$ on contractors with money.

I was going to ask why subs didn't have something like forward-looking radar, then I thought two things:

1) Would that even work underwater?
2) It probably wouldn't be too stealthy. :)

Based on reading The Hunt For Red October 4 times, they have it, but they hardly ever use it because it reveals your position. Also beyond a certain speed your own transient noise drowns out any sonar signal you send out.

As for why nobody ever hit it before, it's a big ocean and earthquakes do change the undersea landscape. Didn't the Indian Ocean EQ drop the sea floor 30 ft?

Yeah right. Not only do we fall under OSHA, the Air Force has their own version of it to further make the CE guys miserable.

Tim G 01-27-05 06:05 PM

So a cylinder full of seamen blindly thrusting forward in an uncharted area at an unknown depth had the tip of it damaged.

I would say in this case it is rightfully named, and lucky.

:D

I can;t believe the thread got this far without the third grade humor ;)

There's a HUGE amount of the ocean that is uncharted, or I should say the charts aren't very accurate, especially in the Pacific. The last time I spent any time around charts was 5-7 years ago, and there are island charts that haven't been updated in 100-200+ years, and those are coastal waters not open water charts with detail of underwater objects which is FAR worse in terms of accuracy, but then they're more for surface ships, so a sea mount 500ft underwater is of little concern. That includes both DMA (Defense mapping agency, now NIMA iirc) and BA (British Admiralty) charts.

Maybe Pat will see this thread and give us some info (if he can), I'd be curious if they use the same types of charts available to the public.

swhiteh3 01-27-05 06:12 PM

It must be tough enough to be in a sub for a long period of time, but to be in sub, in a depth of water that would crush your skull like a Twinkie, and to actually unexpectedly make contact with something like that - THAT must be truly scary. No thanks. I like this whole "land under my feet" thing. :)

The attack submarine entered dry dock Wednesday at the Guam Shipyard, U.S. Naval Base Guam officials announced in a news release.

Does OSHA have jurisdiction in Guam? :)

They have active sonar ("One ping only."). But, no its not stealthy. The one-way loss is a proportional to the Range^2 while the return back from a target is Range^4, just like radar. Sonar is even more complicated since the ocean has thermal layers, a surface, and often an irregular bottom which makes for all sorts of multi-path situations. Basically something listening for you will hear you long before you can detect them. Imagine you're in the woods at night with out a light. Some one with a flashlight is trying to find you. How far away can you see them coming? How close do they have to be to you for the flashlight to be effective?

Submarines typically use passive sonar which just listen for the sounds of other vessels which allows them to hide. Stealth is a submarines biggest asset.

This is just speculation, but I doubt we pay any fines. If AFOSH nails you, you get an ass chewing, probably some paperwork (letter of reprimand, etc), and you fix the problem. If OSHA nails you, they shut down the project (if serious enough) or they contact the AFOSH representative. See above for what happens next.

I guess I should clarify that when I said we fall under both, I meant more of the rules and regs, not necessarily penalties. Of course, it's been so long since I had to attend an AFOSH briefing...

I gave up caring about all things OSHA related when I enlisted

Chris Stack 01-27-05 07:14 PM

Here's my limited knowledge, before LT Olsen jumps in and spills all the beans.

First, under the tarp is the spherical sonar array (big sphere with lots of microphones on it.

Second, even if they were doing a "mad dash" just using the charts, someone would have already plotted out where they were going and have checked it out. In other words, QM2 Johnson might not know everything about what he was doing, but LT Navigator was looking over his shoulder and did. There are only a few ways of doing this: hitting something uncharted, which is possible but I don't know how likely (though so far this is the official word and I haven't heard any rumors different); not knowing where you are, as in you are convinced you are in one spot in the ocean and you are actually in another (not going to "speculate" how often this happens); or not knowing where you are because of some system malfunction (probably not), or poor communication (unlikely); or just basic misreading of the chart, like you thought that line meant 300' of depth, not 30' (probably did not happen). In my experience, and that is to say not very much (1 month each with 2 different 688-class subs), when there is something that you could hit such as a mountain or another contact, the quartermaster is constantly updating the officer of the deck on their location relative to the danger.

As far as the active sonar, correct, they rarely use it (in my ~45 days underway, I bet I saw it used 2-3x, and probably mostly to show us how it works) because of the stealthiness issues. However, there are various ways of knowing where they are, not just some dude with a grease pencil and a chart.

Sub guys are some of the most anal people out there, and also the most well trained and capable. While ship drivers get relieved with some regularity (I think there were 15-19 last year?), it's not as common with subs. Granted, there is also a smaller sample size. Therefore, it's likely (not definite, mind you) that this is not entirely human error. The CO was relieved, but my understanding is that it was more of a reassignment pending an investigation. Not too much gouge on that though, being halfway around the world.


Oh, and BTW...pretty sure they were going flank speed, or top speed....the unclass top speed is "in excess of 35 knots"....so use your imagination.

Disclaimer: most of this was based on knowledge I gained at least 1.5 years ago, so it may not be entirely accurate...also left a few things out because I'm not sure if they are classified or not. But the gist of it is right.

gp001 01-27-05 07:33 PM

I'm not buying the explanation they give. I think they ran into the back of a Russian sub doing a "Crazy Ivan"

Phil 01-27-05 08:31 PM

What's incredible is that we only lost one guy. Thats a big freaking hole there. They were at 500' when this happend!

From strategypage.com:


January 12, 2005: The American nuclear submarine USS San Francisco hit an uncharted seamount on January 7th, killing one sailor and injuring sixty others, 23 of them so seriously they could not perform their duties. Facts about the incident were slow to emerge. It appears that the sub was traveling on a course it was ordered to follow, at a depth of 500 feet and a speed of about 56 kilometers an hour. This was the first time the navy had given the speed of a Los Angeles class sub as anything but “25+ knots” (45 kilometers an hour.) It has long been believed that these subs could make more than 55 kilometers an hour.

The visible damage to the sub indicated that the sonar dome at the front of the sub was partially collapsed, and, according to information released by the navy, some of the forward ballast tanks were damaged. The pressure hull was not compromised. The submarine immediately surfaced after the collision, which was apparently a glancing one, but it immediately slows the sub to about seven kilometers an hour. The crew had some trouble getting to the surface, because of the damaged forward ballast tanks (which hold water, that is rapidly pumped out, and replaced with air, to give the sub buoyancy and bring it to the surface.) The impact, of course, caught everyone unawares, which is why there were so many injuries. The sailor who died, had been thrown forward, hitting his head on a pipe. He died of that injury two days later.

The captain usually losses his command after accidents like this, although in this case, that might not happen. If the captain was following all procedures correctly, and there was no way the seamount could be detected, the incident might not destroy his career. There are many uncharted underwater features, especially 500 feet underwater. The technology does not yet exist to economically chart all of the ocean bottoms to that, and greater, depth. Most waters are charted sufficiently to protect surface ships. But there are only about two hundred subs that normally operate at the depth this accident took place. There may be a call for the navy to change its procedures, and have the sub use more active sonar devices when traveling in certain waters. But this will generate protests, because active sonar disturbs the fish. There are also technical issues regarding how effective such sonar would be in avoiding all types of underwater collisions. Moreover, in wartime, you avoid using sonar as a navigation aid, as it gives away your position. Actually, traveling at high speed gives away your position, because of the noise generated by the propulsion system and water rushing over the sub. In wartime, the sub might have been moving at 10-20 kilometers an hour, which would have caused less damage and fewer injuries.

If the Navy adheres to maritime tradition, that calls for the naming of previously unknown underwater features after the vessel that "discovered' them, even if by running into them, the uncharted seamount will now be known as the "San Francisco seamount".


Accidents like this are rare, but there will probably be a review of the charts, of underwater geography, that are used by American subs. This review process is standard whenever there is a major underwater earthquake or volcano eruption. For example, the December 26, 2004 earthquake off Aceh is known to have seriously rearranged the ocean bottom in that area, and efforts are already underway to update charts. But now an effort will be made to try and determine where there may be other potential "San Francisco seamounts".

"Save the fish! Fuck the sailors!" :mad:
Don't get me going.

Patrick Olsen 01-27-05 10:32 PM

Let's see, where to start...

I still haven't seen an official Navy statement that released the actual speed of the SAN FRAN when she ran aground, so I'm stickin' with the "in excess of 25 knots" that has been the standard answer for a while. (Aside: It used to be "in excess of 20kts and in excess of 400ft" until Diane Sawyer went out on a boomer probably 10 years or so ago for whatever news show she was doing at the time. The CO took it upon himself to "expand" the rules a bit and told her "in excess of 25kts and in excess of 800ft", at which point the Navy's official story had to change. :rolleyes: ) SAN FRAN was at max speed, and pretty much instantaneously came to about 4kts upon striking the sea mount. Much of the crew was up because the ship had just completed a cleaning period, and it was lunchtime. Fortunately, since it was lunch a lot of people were sitting down. If they had run aground during the cleaning period things would have been a lot worse, as there would have been lots of equipment broken out, heavy metal deckplates removed for access to bilge areas, etc. As it was, nobody was injured by any flying equipment - all the injuries were due to flying bodies.

The Executive Officer onboard is a friend of mine who was on my last ship, and one of the junior officers was also on my last ship (although I didn't know him as well, he showed up towards the end of my tour). Both were OK, but the XO in particular was pretty banged up.

At the speed they were going it is a requirement to take a sounding (projecting active sonar straight down, just like a surface ship's bottom sounder or a fish finder) every 15min. Our fathometer in secure mode is pretty much undetectable, so that's not a concern. At high speeds we have to shift to non-secure (due to the increase in own-ship's noise previously mentioned) at which point it is detectable. Transiting from Guam to Australia that's not really a concern, since there's nobody out there to hear it. :) Anyway, SAN FRAN had just gone deep and fast a few minutes prior to the grounding. Prior to any significant depth excursion we always take a sounding, and it was 1000+ fathoms. As I recall that was 4 minutes before the grounding.

There are two charts that cover the area in question. I know one is a LIMDIS (Limited Distribution) classified chart, so it's not available to the public. That type of chart is generally what we use for open ocean navigation, and they have very good sounding data. In this particular case, on this chart there was nothing shown in the area. The other chart, which I think may be available to the public, did show "discolored water" in the vicinity of the grounding, as does our electronic chart of the area (which are still not authorized for navigation, just as an "aid"). Honestly, as a Navigator myself, I can't say I would worry much about "discolored water", as there's really no definition of what that means and often it seems to be old data (as in the chart will be marked "Discolored water (rep 1971)"). I'm not sure where exactly SAN FRAN's track was laid out relative to the discolored water area, but I believe they grounded ~3nm away from it, so it's not like they plotted a track right over it.

NIMA, the chart people, has recently changed to NGA (National Geospatial-Intelligence Agency). I've seen one article since the grounding in which NGA said that they have thousands of photos of the ocean, which can be analyzed with modern technology to determine water depth. However, there's a big backlog, and the area in question had not been analyzed yet. I found the article here: http://www.washingtonpost.com/wp-dyn...2005Jan15.html (one pop-up).

You always hear that a grounding effectively kills a Captain's career in the USN. Do you think that's likely in this case given the circumstances?

PeteRR 01-27-05 11:35 PM

This NYTs article goes into more detail:

Now, Defense Department officials say they have found a satellite image taken in 1999 that indicates an undersea mountain rising to perhaps within 100 feet below the surface there.
---

The officials said the main chart on the submarine, prepared in 1989 and never revised, did not show any potential obstacles within three miles of the crash. They said the incident happened in such a desolate area - 360 miles southeast of Guam - that updating their depiction of the undersea terrain was never considered a priority.
---
But since the accident, Mr. Andreasen said, his office has examined commercially available images taken by a Landsat satellite in 1999, and at least one image indicates that an undersea mountain could rise to within 100 feet of the surface there. Analysts say variations in water color can sometimes indicate a land mass below. Mr. Andreasen said his agency had not normally used satellite imagery to update sea charts, though it recently began using the images to help pinpoint the boundaries of islands and other land masses. He and other officials said that the charting office's staff had shrunk in recent years, and that the Navy never asked it to focus on the area south of Guam, where it began basing submarines in 2002.
---
Current and former Navy officials say the main focus during the cold war was charting areas in the Northern Pacific and in Arctic seas where missile and surveillance submarines guarded against a Soviet attack. Since then, the Navy has been trying to improve charts of shallower coastal waters in the Middle East and other areas where it might have to help battle terrorists.
---
As ships have reported these coordinates, sea-charting offices around the world have found that many islands were "maybe a mile or two out of position" on widely used charts, he said. So over the past year, his agency has been using the Landsat images and other data to update many nations' boundaries.



"a mile or two out of position" Yikes!

Subs don't have doctors onboard, just an "Independent Duty Corpsman", an enlisted man who receives extensive training - an EMT with the ability to do emergency surgery if necessary. Their corpsman (aka "Doc" on every boat, of course) held it together for about three days while treating nearly half the crew, with 23 people who were pretty much out of commission. Truly amazing.

Not to take anything away from their abilities to hold together and get home, but I would assume that if they did an emergency surface, they would be able to call in some sort of airial support to do damage assesment of the boat, bring in more crew members to get her back under way, as well as a few extra doc's or even fly by helicopter the ones who needed imediate med-vac to somewhere that could do the work. Is this the wrong assumption

I say this more because I am curious to here what they could do and also because I would like to hear in more detail about what they had to do to get home.

Drew 01-28-05 12:48 PM

I don't know where the accident happened, but what are you going to do if you're thousands of miles out to sea or away from the nearest part of land that is capable of helping you.

I spent a long summer doing some off-shore sailing, and the realization that the only people you can rely on are yourself and the crew aboard is a bit sobbering. There are places in the ocean where you are truly 1-2 thousand miles from the nearest piece of dry land, you are well out of helicopter rescue range, which means in the event of an emergency you are potentially days away from help (obviously any ships in the area can and legally should come and help, but that's providing you are near other ships/boats).

US navy, British/Australian Navy, Japan's Navy, etc could head your way pretty quick. Also, they were headed to Australia from Guam, and I would assume that it is a pretty common trip for most Navy vessles since moving to Guam in 2002. Of course it would appear that The San Fran was going a route not normally taken, but I would think that ships would be in the area. It's not like they were headed from Guam to Alaska, and even if they were way far away from help, I have a feeling that we could get some sort of air drop on the way that could atleast stablize the situation(making the big assumption that the boat could get to the surface of course).

On another note:
Check out this pic:

It looks like the bulk heads compressed like a crumple zone just behind the guy to left on the catwalk. Notice the bulge I have to wonder just how much of the ship had to be sealed off to get it water tight.

I wonder how much the repairs will cost or if they will retire the ship and part it out for other units still in service. One could only hope that they would update the ship significantly if they put it back into service.

I guess the navy will have some survey ships working under the guise of science out using some sort of observation equipment to map the sea floor in the net few years. The stuff they used to find the titanic seems like it would be up to the task.

Shit, that was what, 20 years ago? I hope they have something better by now! Plus, I'm sure using that technology to do all water bodies would be a little time prohibitive. If I recall correctly, Ballard used "extra" time after working for the Navy to find the Titanic, and he had a real good idea of where it was.

If they were on the surface, an aerial damage assessment would tell you less than someone walking out and looking down. Particularly since the person looking down probably knows what he is looking at more than the guy on the helo. When my brother was on Subs, they had a diver on board, who could do a much better job of damage assesment than anything short of a drydock.

As to a helicopter, IIRC an SH 60 has a range of under 400 miles, which means they wouldn't have enough range to make it to the sub and return to Guam. True, it could come from a nearby ship, but there probably wouldn't be any submariners on board ships, so aside from medical people it wouldn't do much good and may actually hurt (as in they may require supervision). They could evacuate some injured, but as all people would need to go up a ladder and out a ~2 foot hatch, (with the ship rolling in open ocean) then be loaded on a hoist and winched to a helicopter, then flown to a ship. I think the odds favor leaving them in their racks for the couple days it would take to get to port than risking further injury trying to transport them. 350 miles out, even if they could only make 10 knots, they would still make it to Guam in a day and a half.

According to the news articles, none of it. The articles mentioned that the pressure hull was not compramised. With damaged ballast tanks, there was probably some problems controlling bouyancy (as Pat mentioned), but it doesn't sound like flooding was a problem.

They just need to come up with drones that keep going on course at a set depth and broadcast to a satalite.

As for the Pressure hull not being compromised...I saw pat's post but it was unclear to me if that meant they were able to come home with out running evac pumps by sealing doors off or if it was saying that everywhere people are normally working at in the sub while submerged, was not damaged. I guess I was fishing for a little more clarity.

My boss (former USS Louisville Capt.) told me the front of those ships were meant to be able to take a hit like that. He said he had no doubt the ship made it back to port under it's under power.

The only thing he complained about was the sleeping arraingments. He said he fought with designers over having the sailors heads facing the front of the ship while they slept. If they would have hit while sailors were in their bunks it would have probably broke a few necks.

Steel is cheap. The money in subs is in the reactor and the combat system. Though one does wonder if they won't just mothball it since older boats in the class are being retired. The later, improved, Los Angeles class boats had the forward dive planes located forward on the hull not the sail.

I (and many others) are very curious about what the outcome of this will be - will we repair it or not? Part of the deal with "forward deploying" 3 boats in Guam is that all 3 boats are 1st flight 688s that have just been refueled. As a result, they have a new reactor core that will significantly outlast the rated hull age, so we can forward deploy them in Guam and run them all over the place and never have to worry about core consumption. So, the Navy spent lots and lots of $$$ just a couple years ago to refuel SAN FRAN - do we throw that investment away (and put a serious kink in the PAC Fleet submarine employment schedule) or do we spend lots more $$$ to fix her? There are boats of the same flight that have been decomm'd - perhaps it's feasible to cut the nose of one of those and plop it onto SAN FRAN. I really don't know.

The "people tank" was not breached at all - no need to shut any hatches, no need to pump any water out of the people space.

Is this the wrong assumption?

Yes, it's the wrong assumption. I think they eventually got a couple docs onboard, but it took a couple days to happen. Getting people on/off a submarine in the open ocean is not an easy undertaking, particularly when the submarine is riding low in the water (as was SAN FRAN) because half her main ballast tanks have been crushed. Their only option was to do a helo drop onto the sail. They were unable to medevac anyone because the hatch in the sail doesn't open far enough to allow a backboard to exit there.

I think there will be some serious evaluations by structural and naval engineers on her hull to find out what other damage occurred. Although the pressure hull was not breached, that does not mean it didn't deform (permanently) in some manner. The decision to keep her or scrap her would have to based on a full boat inspection, bow to stern, to look at the hull shape. If it is just bow damage, and we can paste in a new bow a al the USS Wisconsin, that's great.

At least if they scrap her, it's not a total loss. She can be a "donor boat" for some other sub nearing EOL for the reactor core.

And no matter what the outcome, this will provide some very good (though costly) data about the design and manufacturing of our subs. You can simulate crashes all day long with FEA, but a real world test is great verification of all that effort. Having the accident occur at flank speed will provide lots of useful data. The sad part is the loss of a life and the injuries :( - but if it happens, we might as well get something useful out of it.

At least when I was on the 'E' we hit mud when we went aground in '83. I can't imagine hitting a solid rock at flank speed (shudder).

I recall someone mentioning early in this thread this was par for the course. I hope more info is released as to the circumstances leading up to the incident.

The following is purported to be the unedited account of the San Francisco grounding written by the on-watch Diving Officer. I received it from a reliable source. I have inserted comments in color to define the jargon or terms that may be unfamiliar to non-submariners.

To say that I've had a bad year so far would be a little short on the tooth I think (understated). Last year was a good one for the boat. After spending 5 months away from home in drydock (Sandy Eggo) we got our second BA (below average) on ORSE (Operational Reactor Safeguards Exam) (bad juju), received the highest score in PacFlt (Pacific Ocean Submarine Force) for a submarine TRE (Tactical Readiness Evaluation, a significant evaluation of the crew's ability to use their weapons systems) inspection, aced (got a high score on) our mine readiness inspection with 4 out of 4 hits, completed 2 outstanding missions (will have to shoot you), and completed a early ORSE just before Christmas with an EXCELLENT.

It was also the first year that Auxiliary Division had a Christmas standown since coming out of the yards in 2002. A-division also took the CSS-15 Red DC award for the second year in a row. My retention has been 100% since I checked on board in Oct 2002 amongst 1st/2nd and turd termers.

We were going to our first true liberty port 2 weeks ago, heading for Brisbane and fun in the sun. As this WOG (a traditional term used by sailors for those who have experienced the crossing the equator, sort of a "right of passage") knows, we were getting ready for our crossing the line ceremony and the crew was really upbeat, and hard charging, we had just completed a great year for the San Fran.

To say the world went to shyte in a hand basket would be an understatement. I would put it closer to a nightmare that becomes reality.

The seamount that is a large part of the discussion the last 2 weeks is un-named. The charts we carried onboard were up to date as far as we can tell. No modern geographic data for this area was available to us onboard as it is a remote area not often traveled by the Navy. We have one of the BEST ANav's (Assistant Navigator) in the fleet onboard, a true quartergasket (quartermaster, the Navy rating that is trained as navigator) that takes pride in his job. We have RLGN's (Ring Laser Gyro Navigation, or, fancy high-end accurate navigation equipment) onboard, when they are running, they are accurate as hell for our position, they also drive Tomahawks (the same cruise missile weapons used in Iraq) .

We knew where we were. All of my depth gauges and digital read the same depths as we changed depth to our SOE (Ship's Operating Envelope, technical specifications for the required minimum or maximum depth for a given speed for a submarine) depth for flank. I can't discuss a lot, because I'm still a participant of at least 2 investigations....LOL.

I was the Diving Officer of the Watch when we grounded. If you read the emails from ComSubPac, you will get some of the details, from flank speed to less than 4 knots in less than 4 seconds. We have it recorded on the RLGN's-those cranky bastages actually stayed up and recorded everything.

For you guys that don't understand that, take a Winnebego full of people milling around and eating, slam it into a concrete wall at about 40mph, and then try to drive the damn thing home and pick up the pieces of the passengers.

As for the actual grounding, I can tell you that it was fortunate that myself and the Chief of the Watch were blessed by somebody. I was standing up, changing the expected soundings for a new depth on the chart (yes, we had just moved into deeper water) leaning against the ship's control panel with a hand grip, and the COW (Chief of the Watch) was leaning down to call the COB on the MJ.

The next thing to cross my mind was why am I pushing myself off of the SCP (Ship's Control Panel, the main instrument and control panel for steering and driving the submarine) and where the hell the air rupture in the control room come from? I didn't know it, but I did a greater than 3g spiderman against the panel, punched a palm through the only plexiglass gauge on the SCP and had my leg crushed by the DOOW (Diving Officer Of the Watch) chair that I had just unbuckled (seatbelts are normally worn at high speeds) from. The DOOW chair was broken loose by the QMOW (QuarterMaster Of the Watch) flying more than 15 feet into it and smashing my leg against a hydraulic valve and the SCP. I don't remember freeing myself from it. If I had been buckled in, I don't think I would be writing this.

The COW (Chief Of the Watch) was slammed against the base of the Ballast Control Panel, and only injured his right arm. He could of destroyed the BCP (Ballast Control Panel), he was a big boy. Everybody else in control, with the exception of the helm, was severely thrown to the deck or other items that were in their way, and at least partially dazed.

Within about 5 seconds of the deceleration! , we blew to the surface, it took that 5 seconds for the COW to climb up the BCP and actuate the EMBT (Emergency Main Ballast Tank) blow.

We prepared to surface right away and got the blower running asap, I didn't know how much damage we had forward but knew it was not good, I wanted that blower running.

I would say that about 80% of the crew was injured in some way, but do not know the number. We grounded in the middle of a meal hour, just after field day, so most of the crew was up. Once we got the boat on the surface and semi-stable with the blower running the rest of the ship conditions started sinking in to our minds.

We were receiving 4MC's (reports over a submarine's emergency-use-only sound-powered phone system) for injured men all over the boat. I was worried that those reports were over whelming any equipment/boat casualties that could make our life worse. I had teams form up of able bodied men to inspect all of the forward elliptical bulkhead, lower level, and tanks below those spaces. I couldn't believe that we did not have flooding, it just didn't fit in. At one point I looked around in the control room, and saw the disaster. The entire control room deck was covered in paper from destroyed binders, and blood. It looked like a slaughterhouse, we had to clean it up.

I knew that Ash (MM2(SS) Joseph Ashley, the only crewmember that did not survive the grounding) was severly injured and brought to the messdecks, he was one of my best men, and one of our best sailors onboard, he was like a son to me. After surfacing I was the control room supervisor, I had a boat to keep on the surface and fight and knew that if I went below to see how he was doing, it would teeter me on the brink of something that the ship did not need, the ship needed somebody who knew her. I have to say that the design engineers at Electric Boat, NavSea and others have designed a submarine that can withstand incredible amounts of damage and survive. We lost no systems, equipment, or anything broke loose during the impact. The damage to our sailors was almost all from them impacting into the equipment.

The crew is a testament to training and watch team backup. When a casualty occurs, you fight like you train, and train like you fight. It kept us alive during that 2+day period.

I've just returned from the honor of escorting my sailor home to his family. God bless them, they are truly good people and patriotic. The Navy is doing everything they can for them and they are learning how submariner's take care of each other. During the memorial and viewing on Saturday, CSS-15 (Commander, Submarine Squadron 15) provided a video from the coast guard of us on the surface and the SEAL/Dr. medical team being helo'd in, the family had this video played on 2 screens in the background. It was a sobering reminder of what a hard woman the ocean can be. We had to call off the helo because of the sea state, it was becoming too dangerous for the aircraft, we almost hit it with the sail a couple of times.

The sea would not allow us to medivac (evacuate people for medical reasons) in our condition and that sea state. I was one of the 23 sent to the hospital that Monday. I was fortunate, my leg was not broken, just trashed/bruised. I walked on that leg for almost 24 hours before it gave out on ! me and they had it splinted. The SEAL made me promise not to walk on it, how do you refuse a SEAL? LOL. So I hopped around on a single leg for awhile, the other chief's were calling me Tiny Tim, LOL. "God bless each and every one! Except you, and you, that guy behind you!". The COB (Chief Of the Boat) threatened to beat my @ss if I walk onboard before my leg is otay, he's about the only man onboard that I'd take that from, hehe.

The crew is doing better, we've lost a few due to the shock of the incident. We will make sure they are taken care of.

The investigation goes on, and I have a new CO. I will only say that the San Fran was the best damn sub in the Navy under CDR Mooney's leadership. We proved that. God bless him and his family no matter what happens in the future, he is truly a good man.

I just need to get my leg healed and get back to fighting my favorite steel bitch (working on his favorite submarine).

Lewis Tanner 03-08-05 05:33 PM

So they give a commander a bum set of charts, he uses them properly, hits a rock, and they end his career? I wonder if any Navy cartographers will lose their job over this, or just the guy that was using their map?

PeteRR 03-08-05 06:00 PM

It's the nature of the beast. IIRC, there was an article in USNI's Proceedings 20 years ago concerning washing out potential Captain's over minor shiphandling mistakes would have derailed Admiral Nimitz's career. He'd grounded a destroyer as a junior watch officer and the incident didn't prevent him from advancing.

Patrick Olsen 03-08-05 11:16 PM

I can't say anything, but I've read the mishap report detailing the results of the initial investigation. There were things the chain of command could/should have seen that would have prevented the grounding - that's why the CO was relieved.

Quote:

May 9, 2005: The U.S. Navy investigation of the submarine USS San Francisco’s collision with an uncharted undersea mountain revealed the basic cause, and then blamed the victim. The sea mount the San Francisco hit had been spotted by survey satellites in 1999 and 2004, but the intelligence agency responsible, the National Geospatial-Intelligence Agency, said it didn’t have the money to update naval charts. Neither did the navy, or anyone else. Someone made a decision to let American submarines continue moving around amidst all manner of uncharted hazards, but that angle was not pursued by the navy investigation. Instead, the sailors on duty when the San Francisco hit the sea mount were punished for not having taken more frequent depth soundings (which would have indicated they might be approaching an obstacle), or consulting another map (than the one the originally used) that showed a possible sea mount five kilometers from where the actually collided with one. Whatever happened to responsibility at the top? The U.S. has been using expensive survey satellites to map the oceans for over a decade. What’s the point of spending all that money if you don’t get vital information to the people in the submarines and ships who can use it? But this is not a unique situation. The troops have been complaining, with increasing frequency and anger, that the $40 billion a year we spend on intelligence is not getting much to the end user. After the 1991 Gulf War, you had generals saying this in blunt testimony before Congress. After September 11, 2001, the same complaints were made. Same thing after the invasions of Afghanistan and Iraq. And the complaints continue to come in. Blaming the victims is pretty lame, and disrespectful of the hardest working and diligent sailors in the U.S. Navy. Will anything change? According to the navy investigation of the USS San Francisco accident, it’s unlikely. The intelligence community has enormous power to spend their billions, but no responsibility for the results.

Medical Report
Quote:

Three and a half years after the American submarine USS San Francisco hit the top of an underwater mountain, the medical report has been released. The collision, of a sub moving at over 50 kilometers an hour, smashed the sonar equipment that fills the bow (front) of the sub, as the boat careened off to one side. The sub's sudden change of speed and direction was unexpected by the crew. Thus 90 percent of the 138 man crew were injured. One sailor later died. Most of the injuries were minor, but a third of the crew had serious problems (nine had broken bones, two had dislocated shoulders, nine had concussions and 23 had cuts). Fortunately, the two sailors with medical training were not injured, and were able to prevent all but one of the injuries (a bad concussion) from getting worse. The navy is used its study of the San Francisco medical situation to make changes in how subs are equipped, and sailors trained, to deal with large scale injuries. The navy also noted that 15 percent of the crew still had psychological problems months after the accident. This is not unusual for sailors involved in a large scale accident.

But there were other reasons for poor morale among the San Francisco sailors. The sea mount the sub hit had been spotted by survey satellites in 1999 and 2004, but the intelligence agency responsible, the National Geospatial-Intelligence Agency, said it didn't have the money to update naval charts. Neither did the navy, or anyone else. Thus American submarines were allowed to continue moving around amidst all manner of uncharted hazards. Instead, the sailors on duty when the San Francisco hit the sea mount were punished for not having taken more frequent depth soundings (which would have indicated they might be approaching an obstacle), or consulting another map (than the one originally used) that showed a possible sea mount five kilometers from where they actually collided with one.

The navy held the crew responsible for the collision. Six members of the crew were given non-judicial (no court martial) punishment for their actions, or inactions, that caused the accident. At the time (January, 2005), the sub was traveling at high speed and at 500 feet depth. The six sailors punished included officers, senior NCOs and lower ranking sailors. Punishment ranged from letters of reprimand to reduction in rank. The charges were hazarding a vessel and dereliction of duty. The investigators concluded that these six crewmen could have detected the approaching sea mount and taken evasive action if they had followed proper procedures. The captain of the sub was earlier relieved of command.

At the same time, the navy also gave awards, for helping save the submarine after the collision, to eighteen NCOs and two officers. These included two Meritorious Service Medals, nine Commendation Medals, four Achievement Medals and five Letters Of Commendation.

The lack of courts martial indicates that the navy didn't feel it had strong enough evidence for that approach, which is more like a jury trial, and demands more compelling evidence. The non-judicial punishment hurts, but does not destroy, the career of a submariner. This is because the navy has a hard time recruiting qualified people for this kind of work. The navy could have held one or more courts martial, but apparently were convinced that just using the non-judicial punishment would get the matter behind them with a minimum of fuss and penalty. The charges in the non-judicial hearings were of the you should have seen this coming and been more cautious variety. Anyone who knows anything about nuclear submarines, and their crews, knows that these are the most cautious and deliberate sailors in the fleet. Eventually, more details of these proceedings, and the collision itself, will come out.

Patrick Olsen 09-21-08 12:44 PM

I'm not sure I agree with the way strategypage.com characterizes the intelligence problem. They make it sound as though NGA knew there was a seamount at that location and willfully decided not to put it on a chart. That (in my understanding) is not the case. First of all, the satellites aren't able to tell exactly what is there, or how far below the surface it is - they can just tell there's something there, and thus a survey ship should go accurately survey the area. And that assumes that the data from the survey satellite has been processed and that there has been human interaction with the data so that someone actually knows there's a seamount there. When we were trained on all the lessons learned immediately following the grounding we were told that NGA "found" the seamount as a result of the SAN FRAN grounding - they went and did a targeted search through the satellite survey data and found that yes, there's something there.

As with many of the intelligence agencies, all the money invested gets you lots of cool toys (satellites and other gadgets) that gather shit-tons of data. But it still takes some sort of human interaction to extract information from that data, and that's where NGA was lagging behind. There's no easy fix for that. And once you've identified that there's a spot that needs to be surveyed out in the deep blue sea, you run into the fact that there are only a small number of survey ships around the world to do such surveys. As I recall less than 1% of the ocean bottom has been accurately surveyed by those ships.

Even without that possible seamount shown on the chart, there was enough data available for them to have realized that doing All Ahead Flank in that area was not prudent, which is why people were held accountable.

How the heck do you hit a reef in what is one of the most charted ports in the world? And what is the typically visibility off Honolulu? 25'? Hell, you should have been able to just look out the window and say, "Hey, Cap, you might want to steer to starboard so we don't hit that reef."

Even in the GPS age, the ship doesn't drive itself. You have a crew that hasn't been to sea in at least 4 months and they're going to be rusty. Combine that rustiness with some complacency ("Just a routine small boat transfer off the reef runway...") and next thing you know you're in a bad spot.

So who was stalking whom?

Quote:

BRITISH and French nuclear submarines which collided deep under the Atlantic could have sunk or released deadly radioactivity, it emerged last night.

The Royal Navy’s HMS Vanguard and the French Navy’s Le Triomphant are both nuclear powered and were carrying nuke missiles.

Between them they had around 250 sailors on board.

A senior Navy source said: “The potential consequences are unthinkable. It’s very unlikely there would have been a nuclear explosion.

“But a radioactive leak was a possibility. Worse, we could have lost the crew and warheads. That would have been a national disaster.”
The collision is believed to have taken place on February 3 or 4, in mid-Atlantic. Both subs were submerged and on separate missions.

As inquiries began, naval sources said it was a millions-to-one unlucky chance both subs were in the same patch of sea. Warships have sonar gear which locates submarines by sound waves.

But modern anti-sonar technology is so good it is possible neither boat “saw” the other.

A senior military source said: “The lines between London and Paris have been hot.”

The MoD insisted last night there had been no nuclear security breach. But this is the biggest embarrassment to the Navy since Iran captured 15 sailors in 2007. The naval source said: “Crashing a nuclear submarine is as serious as it gets.”

Vanguard is one of Britain’s four V-Class subs forming our Trident nuclear deterrent. Each is armed with 16 ballistic missiles.

She was last night towed into Faslane in Scotland, with dents and scrapes visible on her hull. Triomphant limped to Brest with extensive damage to her sonar dome.

Triomphant has a crew of 101. Vanguard weighs 16,000 tons, is 150 metres long and has a crew of 140.

The MoD said it did not comment on submarine operations.

Patrick Olsen 02-16-09 12:13 AM

Huh, very interesting. Being on the left coast I hadn't heard anything about this. I'll have to see if I have any compadres in the Lant or Med that might have some details (not that I could post them here, of course :) ).

Since pretty much every country in Europe has subs, AFAIK they all deconflict waterspace with each other so that this sort of this can't happen. My thinking is this isn't a case of who was stalking whom, but instead is a case of who wasn't where they were supposed to be?

Pat

PeteRR 02-16-09 12:17 AM

I guess so. You would think that with both being boomers they would avoid contact, let alone getting close enough to collide.

Lewis Tanner 02-16-09 08:14 AM

The French have been getting something of a reputation with regard to their aggressive sigint/RCS activities over the past decade. They're known for putting enough RF on new planes to pop a bag of Pop (top?) Secret every chance they get. Probably selling the data to Iran or at least setting up the marketing pitch that the weapons they have on the market are effective against xx platform... (speculation)

Emitters? I can't see a reason for an aircraft to emit a ton of RF other than an AWACS-type of bird, and you typically don't have a ton of those in your arsenal.

(Yes, warbirds have targeting radar, and most everyone has weather-type radar. I'm talking about light-up-the-entire-sky, flying-aircraft-traffic-controller radar here.)

I believe he is referring to how much RF the French are aiming AT the new planes in order to generate target profiles, etc. Hence the selling info to Iran comment afterwards.

Ah -- I see. I've never worked with active RF (radar, etc...) The stuff I did Way Back When was entirely passive (i.e. listen to the RF spectrum and identify known signals hiding out in all the static.) It's a lot harder for the enemy find you if you're not spraying RF all over the place...

Lewis Tanner 02-16-09 10:34 AM

I was referring to the latter. The last time they showed up to red flag, it was pretty much a recon mission to gather electrons from every asset they could spot. We didn't take the F-22 to Paris for the longest time because we knew the frogs would burn the paint off of the thing trying to get a profile they could use. Not to mention the "customs" inspection...

I can only surmise their efforts are just as aggressive in the field and in other branches of the military. Then again, the Brits probably like to sniff butts to get a feel for how their neighbors do business from time to time as well. I know diddly about sub ops - would it even make sense for two ICBM boats to interact?

Not at all. The more I think about this, the more I think it's gotta be either a navigation error or a coordination mistake. Either someone's inertial navigators were on the fritz, or someone got assigned the wrong waterspace.

Or, maybe the information just isn't shared, which is what an article on Time's website is now saying.

(See a graphic of the global nuclear arms balance.)

"There is a system for operating areas that are reserved for American, British, Norwegian, Dutch and Canadian communities and if you want to go into someone's area of influence you tell them what you are doing. But if you are not in the NATO military structure you don't have to do that," says Ferguson.

The French Navy confirmed to TIME that it does not give the positions of its nuclear armed submarines to NATO forces: "France does not supply any information regarding the position of its nuclear arms or submarines carrying them, because France considers its nuclear arsenal the most vital element in its defense capabilities," says Jérome Erulin, spokesman for France's Navy.

So there you have it. A break-down of the "big ocean, small boat" theory. Two modern, very quiet SSBNs creeping along on patrol aren't going to hear each other until they're extremely close.

I do love the ridiculously paranoid press release from the anti-nuke nannies:

"The dents reportedly visible on the British sub show the boats were no more than a couple of seconds away from total catastrophe."

:rolleyes: The PHILADELPHIA was hit by a 600+ft, 35,000 ton merchant while on the surface a few years back near Bahrain. The merchant's bow hit a little ways aft of the sail and the merchant rode up and literally drove over the top of PHILLY and got hung up on the sub's rudder. Even a 35,000 ton merchant did nothing but dent the hull. The KURSK had an onboard explosion that tore the nose of the ship off, yet there was no damage to the reactors. The SAN FRANCISCO came about as close as could be to being lost when it slammed into that seamount at 35+mph, and there wasn't any hint of damage to the reactor. The THRESHER and SCORPION, both of which were lost in the 1960s, still have released nothing to the environment (I'm not sure if there's more recent data available, that was the first I found in a quick search). It would take something pretty frickin' catastrophic to rupture the hull and damage the reactor to the point that radiation was released to the environment, but of course the no-nuke nannies wouldn't let a little bit of fact get in the way of a good opportunity to spread fear and misinformation. :mad:

That's a lot of trees supporting that ship. That's just damned impressive.

That's WAY higher than when my ship was drydocked in Long Beach, no doubt to clear the bulbous bow. I always had to stoop somewhat to work underneath it. Eerie feeling to know you might get squished if someone miscalculated something or the big one came along.

Try that under an Aircraft Carrier (CVN-65)...I only had to go once under there and it was once too many.

Initially, the only damage mentioned was to the propellers (the tips were torn off), and a leak in one of the sonar domes. There was no hull breach. But even then, it was believed that the propeller shaft and shaft bearings would have to be replaced as well.

The actual damage turned out to be far worse. The drive shafts and the steel supporting them were twisted out of alignment as the ship was rocked back and forth. It's feared that this damage might be so bad that the drive shafts, reduction gears and engines might have to be replaced. This could cost tens of millions of dollars.

The sonar dome has to be replaced, and the hatches for some of the missile cells (silos) were also twisted out of alignment and have to be replaced. Some of the sensors and antennae on the main mast were twisted out of alignment by the shock of hitting the reef, and have to be repaired or replaced. Instruments and sensors on the bottom of the ship were destroyed or damaged by the grounding. The water exhaust and intake ports in the hull were jammed with debris, and have to be repaired or replaced (otherwise the sanitation, air conditioning and ballast systems will not work)

What are the rows of pad-eye's along the hull for?

Damn True 03-07-09 04:15 PM

From the S.F. piece:

Quote:

The lack of courts martial indicates that the navy didn't feel it had strong enough evidence for that approach, which is more like a jury trial, and demands more compelling evidence. The non-judicial punishment hurts, but does not destroy, the career of a submariner. This is because the navy has a hard time recruiting qualified people for this kind of work. The navy could have held one or more courts martial, but apparently were convinced that just using the non-judicial punishment would get the matter behind them with a minimum of fuss and penalty.
Bullshit. They do an NJP when there is a systemic problem that they do not wish to have examined openly. Had they gone to Courts Martial the issues would have been examined from every angle and heads other than those on the boat would have likely rolled.

How the heck do you hit a reef in what is one of the most charted ports in the world? And what is the typically visibility off Honolulu? 25'? Hell, you should have been able to just look out the window and say, "Hey, Cap, you might want to steer to starboard so we don't hit that reef."

Looking at the photos it seems like they may have hit a sandbar rather than a reef. Having served in Astoria Oregon (Colombia river bar) and in Hawaii I can assure you that sandbars move.

There are a number of them along the Oahu south shore that move around quite a bit. South swells will create, erase and expose surf spots that weren't there a week ago.

"Hogging in," whatever that is.

Two U.S. Navy Vessels Collide in the Strait of Hormuz

From Commander, U.S. 5th Fleet Public Affairs

MANAMA, Bahrain – A U.S. Navy submarine and U.S. amphibious ship collided in the Strait of Hormuz early Friday morning, March 20, 2009.

The collision between USS Hartford (SSN 768) and USS New Orleans (LPD 18 ) occurred at approximately 1:00 a.m. local time (5:00 p.m. EDT, March 19).

Fifteen sailors aboard the Hartford were slightly injured and returned to duty. No personnel aboard New Orleans were injured.

Overall damage to both ships is being evaluated. The propulsion plant of the submarine was unaffected by this collision. New Orleans suffered a ruptured fuel tank, which resulted in an oil spill of approximately 25,000 gallons of diesel fuel marine. Both ships are currently operating under their own power.

The incident is currently under investigation.

Both the submarine and the ship are currently on regularly scheduled deployments to the U.S. Navy Central Command area of responsibility conducting Maritime Security Operations (MSO).

MSO set the conditions for security and stability in the maritime environment as well as complement the counter-terrorism and security efforts of regional nations. MSO deny international terrorists use of the maritime environment as a venue for attack or to transport personnel, weapons, or other material.
Whoops. :(

What? Why were our Navy boats near Iran? What were they up to? This will be seen as inflammatory to their Govt. These renegade cowboys in the Military must be reined in.

The overwhelming majority of the sail is a free-flood area. The watertight portion is the bridge access trunk, which runs vertically from where the guys are sitting straight down. There's a hatch at the pressure hull, and then another in the bridge cockpit about 4 or 5 feet below the top of the sail.

And yes, that sail is fucked.

This is the second time the Hartford had a run in with something other than water. She ran aground in 2003 off Sardinia (Italy) in the Med.

The account of what led to the grounding was amazing if not good for a few chuckles ala Keystone Kops:

Dylan Savage 03-23-09 11:57 PM

What's up with all the US Subs seeming like they're running into shit lately? Has it always been like this and we just didn't hear about it? They had the Japanese fishing boat thing, the japanese tanker thing, the san fran running into the seamount, now this.. is it just a bad decade or are we driving these things pretty aggressively?

Patrick Olsen 03-24-09 12:30 AM

The rate of collisions/allisions/groundings has stayed pretty consistent for years (just to show an example), despite lots of effort to learn from the mistakes of others and avoid these sorts of things. There have been some particularly high profile incidents in the recent past, but it's not like all of the things you mentioned just happened the other day. It may not seem like it, but the sinking of the Ehime Maru off Oahu was just over 8 years go.

And yes, the Hartford grounding is one that just makes me cringe, particularly as a former Navigator. We actually just had training on that one last week with our officers and navigation team - that whole "learing from the mistakes of others" thing in action.

Based on the damage do you think the Sub was submerged except for the exhaust pipe? Looks like the surface ship's draft made contact with the top of the tower but not the rest of the sub.
