Remarkable.So there are some intelligent questions here about how she (711) made it to the surface; didn't flood out; survived, etc. I never inspected the boat. All I can see is the same photos you see. But I am familiar with the 688 and 688i class, and all subs share common features, so...
711 was lucky. She hit the seamount nearly head-on. For a sub, that's the best angle to have a collision at. They are weakest on a "broadside" hit, so there's that. Next, from what I can tell, the pressure hull...which is the hull within the hull, and keeps water out of the proverbial "people tank" wasn't broached, or at least not fatally. It's likely that there was some water intrusion into the hull, but it probably fell within the boundaries of a "controlled leak", where the pumps could keep up with the inflow, as opposed to "flooding", in which they could not.
Subs have ballast tanks at the bow and the stern. Usually three at each end. They are outside the pressure hull. These are flooded to make the boat submerge, and blown dry (nearly dry) to make the boat surface. There are a host of other tanks, both inside and outside the pressure hull, that are used for similar and other purposes, but the ballast tanks are the way she submerges and surfaces. They are big tanks. Tons of seawater.
So her (711's) forward ballast tanks were all but destroyed, which means when she did surface, she would have been down by the bow. There are ways to mitigate that somewhat, which I'm sure she did, but that still had to be a desperate fight to get her on the surface, and keep her there. That crew did a helluva job to save that boat.
I hope that answers any remaining questions. I'm pretty much up against the limit of what is unclassified, so let's just leave it here. If you're really interested in this sort of thing, there's a ton of information out there on the 'net. Suffice to say, if you could get a tour of a modern attack or missile sub, and they were allowed to show or tell you exactly what their actual capabilities were, you'd want to sign up on the spot. And I've heard that the 774 Class (Virginia's) are even better than that.
Way back in '92, on the old BillyBoat, we were SpecWar capable, and we didn't fear or worry about a damn thing that we might run in to. And that, my VN brothers and sisters, was a long, long time ago. Odds are we'd be a Third Rate ship at best today.
Now...if you dare go down that path...do some research on the USS Scorpion (SSN 589). Don't believe the first thing you read. Look at the pictures of her wreck and ask yourself "what took that great big chunk out of the base of her sail?"
FWIW, the Soviets blamed us for the K129. Both were "lost" in '68, which was when John Walker was serving as a Comms Watch Officer at SubLant.
Remember, I warned you...
And as always, appreciate the insight.
