woah.

Its amazing it actually made it to the surface and held on long enough for help to arrive.

This was posted in OT.

The inner pressure hull behind the nose cone held but barly, looking at the bulge in top shows the inner hull had to be close to breaching.

They were very very lucky.

Dang that is some serious damage... I had no idea it was that bad!

 

[OrByte]

damn look at that buckling on top!!

that sucker was ready to drop...amazing engineering.

and some luck too!

just curious, what is typically located inside that section of a sub? ie what got all busted up?

I believe there is a large space for the sonar up there which crumpled and probably saved the sub. This is according to someone at work who was on a sub for a few years.

I'm not one prone to conspiracies; but how the heck can THAT much damage be caused merely by running aground? It would seem like there'd have to have been a major explosion to cause that much damage.

It doesn't appear to be a steel structure, more of a covering to the sonar transponder system.
The post above yours shows the make-up of the Los Angles Class Subs, and there it mentions
that it's like a fiberglas shroud to allow passage of sound waves from a device.

The make-up of the subs sonar system looks to be a mechanical attempt to duplicate what a
whale uses for it's sonar system - a large oil filled organ to send and receive sound waves.

You can see where the steel skin was shredded almost to the point of where the retractable bow plane is. I can understand the FRP shroud getting shredded, but the steel that's missing on the skin is pretty amazing.

The damage does go a fair way back past the fiberglass bow. The bashed in hull plating and mangled torpedo tube doors are a little scary. The ballast tanks are supposed to be up there somewhere too.

:Q

 

[CaptnKirk]

Most of the forward baffle is intact, the forward bulkhead is still not crushed, so it didn't get
into the ballast and vertical launch tube area. Torpedo tubes are further back on the sides.
The damage extends back towards - but short of the retractable bow planes.

The outer hull structure is peeled back pretty severly on the left side though.

You've got something the length of a football field running along at 30 miles an hour running
into an uncharted reef - like hitting the side of a mountain and tearing back a fender.

USS SAN FRANCISCO - # 711

Nearly 7,000 TONS going up to 38 MPH underwater.

From the data sheet:

Bow is built of glass-reinforced plastic (GRP) as a streamlined
fairing over the spherical BQQ-5-A(V)1 sonar array.

IIRC, the sub was traveling at over 30 knots (pretty fast for under water), something that heavy runs into a mountain, theres bound to be a good amount of damage.

Those poor whales, dolphins and even humans. Ear drums? What ear drums?

 

[Grunt03]

I wonder what the total repair cost is going to run?
We should make the Captain pay for it........

wasnt his fault. The charts provided by the Navy didnt have the mountain on there. Whoever makes the maps maybe?

Looky There! the LA Class subs get their power from a giant green pea!

 

[lozina]

I'm guessing there's some sensitive equipment under that tarp...

 

[d3n]

Charts or no charts the Captains career is finished.

 

[MadRat]

It still looks like damage from striking something above it. Pretty common in cat and mouse games, eh, Kirk?

Something big & stationary - like a undersea mountain or reef on the port side.

Damn that Red October anyway !

(Remember the chase scene through the trench)

 

[MadRat]

From the angle of compression it would appear to have been more than just a glancing blow.

If 7000 tons was moving at even a few knots it should have been catastrophic to the entire structure. Its not like we're talking an M-1 tank here.

Edit: I'm going to have to backtrack on this one. The entire nose is contaminated with debri that looks like mud. The tugs that brought her in obviously rubbed against her and created the clean spots along the sides; that must be mud to come off so easily. The damaged nose cone appears to have pretty well been the main damage, as even the sonar's mounting is intact. It must have struck something soft and malleable otherwise that mounting should have been crushed. The point that really makes me change my mind is the lack of shape to the compression. Its all so uniform damage. If it struck something like a ship then it would of had impact damage, and further damage from after the initial collision which seems to be lacking.

Are piles of mud common out in the middle of the ocean?
