very strong hull it's got then.. wonder if it could implode at certain depths with this damage... anyone?

Some pics of it in drydock. It is truly remarkable that the damage sustained and the sub made it home

Didn't hear on the news? The sub hit an uncharted underwater mountain at about 30+ knots. It happened near Guam if I'm not mistaken. 1 Sailor killed, another 24 injured I believe.

I'll admit, I'm a total idiot when it comes to subs. Why the blue tarp? Is there some sort of sensitive equipment (SONAR?, torpedoes?) up there?

History of USS SAN FRANCISCO:

USS SAN FRANCISCO was built at Newport News Shipbuilding in Newport News, Virginia and was commissioned on 24 April 1981. After initial shakedown operations, the ship joined the Submarine Force, U.S. Pacific Fleet and transited to its homeport of Pearl Harbor. While enroute, the ship conducted its initial visit to San Francisco, participating in Fleet Week 1981.

During its first operating cycle the ship completed deployments to the Western Pacific in 1983, 1985, and 1986, conducting a variety of operations and exercises as a member of the U.S. Seventh Fleet. The ship conducted independent submarine operations deployed to the Northern Pacific in 1986 and 1988, and earned the coveted Battle Efficiency "E" for Submarine Squadron SEVEN in 1985 and 1988.

During a demanding DEPOT Modernization Period (DMP) at Pearl Harbor Naval Shipyard in 1989-1990, the ship was equipped with the newest and most capable submarine sensor and combat systems and made fully ready to perform the variety of missions assigned to the submarine force.

Following the DMP, SAN FRANCISCO completed sea trials and a series of rigorous certification inspections and returned to the fleet to resume operations. Two highly successful deployments to the Western Pacific were completed in 1992 and 1994 with ports of call in Hong Kong, Singapore, Chinhae, South Korea, Guam, Sasebo, Japan and Yokosuka, Japan. In December 1994, the ship conducted a dependents cruise to Lahaina, Maui.

In January of 1995, SAN FRANCISCO was awarded the 1994 Commander Submarine Squadron SEVEN "T" for excellence in tactical operations. SAN FRANCISCO was also awarded the Meritorious Unit Commendation for its outstanding performance during the WESTPAC deployment in 1994.

USS SAN FRANCISCO was the host ship for the COMSUBPAC Change of Command ceremony on February 23, 1996. From June - December 1996 the ship deployed to the Western Pacific, visiting Yokosuka and Sasebo, Japan; Subic Bay, Philippines; and Guam, USA.

In October of 1999, SAN FRANCISCO returned to it's namesake city of San Francisco to participate in Fleet Week 1999.

In its life, USS SAN FRANCISCO has carried the pride and charm of its namesake city to the far reaches of the Pacific including: Pattaya, Thailand; Hong Kong; Yokosuka and Sasebo, Japan; Okinawa; Subic Bay, Philippines; Singapore; Guam; Chinhae, Korea; Perth, Australia; Esquimalt, BC; as well as the stateside ports of Bremerton, Washington; San Diego and San Francisco, California; Lahaina, Maui, and Kona, Hawaii.

In 2000, SAN FRANCISCO changed homeport to Norfolk, Va., and on December 18, 2002, the submarine again changed homeport to Apra, Guam.

Why the blue tarp? Is there some sort of sensitive equipment (SONAR?, torpedoes?) up there?

that is where the main active sonar dome is. it's a sensitive piece of equipment.

navyLCDR
01-27-2005, 02:13 PM
The damaged sonar dome is covered by the tarp.

I was out with the PCO for the Seawolf last week. He didn't point any fingers, but did have some interesting observations. First, no sea mount is found out of an underwater mountain range. That being the case, the charts used show the depth of the highest sea mount below the surface. If the range in that area had sea mounts that were no deeper than 400 feet below the surface, then why would one go flank speed at 525 feet through the range?

Well... it's gonna cost lots of money to retire a ship also. So both ways, we're going to spend a good bit of cash. Plus, we need lots and lots of those subs out there. Now that there is a lot of naval forces getting the Russian Kilo Submarines now, we need subs out there to follow, track and god-forbid, sink them in an event of war.

Cheers, looks like a glancing blow...allthough a very bad one..i am still amazed they made it back. They did an amazing job getting it back..there is gona be medals for someone/

maybe its just me, but it looks like the sub got hit directly on its left side and not straight ahead as was reported. Check out the high res, it looks like its caved in and not like it was hit....no scrape marks. Also, if it hit this mountain head on, why is the sonar suite still partially in its orginal shape? Wouldn't it look like crushed tin can?

There are also aliens buried at area 51, and elvis is hanging with santa claus and the easter bunny in the land of misfit toys :)

Its a tough one..there is no compression fore to aft on the centre line bulkhead yet there is lots of fore to aft compression on the hull plating port side..yet there is a bit of an indenation aswell...its mysterious.
Still going for the glancing blow on something more solid than another sub.

very strong hull it's got then.. wonder if it could implode at certain depths with this damage... anyone?

There are two main hulls to a submarine, the first that was damaged is exposed to the outside and contains sonar, ballast tanks, etc. The other internal hull is where all the "innerts" of the sub are, i.e. people and electronics. As long as this second hull is not punctured, I'm sure the contents of the sub (people) would not risk an implosion.

No, it isn't possible that that is what happened. Get out of the conspiracy theory mode before you make the rest of us dumber. We had no collisions during the Cold War that resulted in this extensive damage.

hey jerkoff, I did my time and I'm done taking orders from officers like you (if your even in the navy). I was just responding to someone else's post, you don't need to be such an asshat newbie, and yes a collision between 2 subs at 30+ knots COULD in fact do that much damage
(and more depending on where it was struck) to the outer hull. I was not saying that is what happened just saying that if in the unlikely event that it was we would never really know. personally I think it did hit the mountian, but you never stopped to think about that did you? you just made an assumtion based on one half-serious post that I made. Try posting again when you've pulled your head form your ass.

That picture's kind of deceiving. This (http://www.navy.mil/management/photodb/webphoto/web_050127-N-4658L-030.jpg) gives a better idea of the size of the sub.

might be rust from interrior compents that were exposed to ocean water after the hit. I doubt the stuff on the inside was designed to resist salt water, but I could be wrong.

uhhh the kursk sank due to an explosion in the torpedo room, it did not hit another sub. Early on during the disaster some russian officers said there was a collision but they backtracked from that.

Also u would have to be sucidal to get that close to a russian submarine during a major exercise with half the russian navy about, and considering the magnitude of the kursk explosion, i dont think another submarine (if there was one) would have survived....

A couple of inches of HY120 steel plate reinforced every foot or so with more inches of steel is some stout stuff. And, youíre right, that crumple zone, sonar dome and angle of impact helped save the boat.
Most importantly, the San Francisco's crew was well trained and Iím sure it will be proven they did everything right. Wait till you hear the whole story!

Since the earthquake off Indonesia, there have been reports of major undersea topography changes. Some shipping channel soundings in the region have changed dramatically. I think itís probable the sub did hit a previously unknown or shifted seamount even that far away from the epicenter.

I am split..something stationary and solid a glancing blow such as an under sea prominatory. Or like someone else pointed out two approaching subs, but if they are talking such high speeds i think the damage would be worse, but i guess there isnt that much mass in a sub that size? i dunno its mysterious indeed. Whats certain is they did a great job building it and the crew in getting it back.

Ouch

I didn't know submarines were made of (what looks to be) fiberglass. By the way, was the hull breached?

ElHombre
01-28-2005, 11:40 AM
the front sonar dome is made of fiberglass in order to make the sonaer work better. it is part of the outer hull, not the inner where the crew is. the rest of the hull is steel, often with a special sound-reducing coating.

There were some topographic changes, but I doubt that new mountains appeared. ;)

I am watching these photos again and I have an impression that the submarine hit something with the TOP left side of it nose. I heard when the submarine is coming from underwater position it's its sonar is turned off, so thats why they didn't see anything.

is that for a attack sub - not a boomer right? a boomer cost a lot more right? do to all its missles and stuff?
