OH, I checked. Actually they use ***1082;***1075;***1089;/***1089;***1084;2
(kilogram force per square centimeter ... darn Google Translate...)

Well, the thing is kilogram is not a unit of force but of mass. Where as a newton is the metric unit of force. Where as in the English system, a lb is a unit of force and the slug is the unit of mass..

Are those numbers up their kg/cm^2 or are the N/cm^2 They seem kinda high to be in kg.

Not being an full on sub expert, but inquisitive.. I have to ask.

What could burn on a metal sub for 6 hours?(no petrol, its nuclear, right?)

I am curious, I am not trying to start some lame conspiracy crap.

Seal the dang hatches and let it burn itself out?
Maybe that is why is burned for so long? Such a shame for such a fine ship.

Good thing they were not at sea when it happened. I hope all our boys are ok.

(lulz at peroxide based torpedo propulsion some other (real life) moron proposed to me.)

Le Sigh.....

Google and Wikipedia are your friend.

ALL U.S. Naval vessels currently in commission are Pressurized Water Reactors.

The USS Seawolf (SSN 575) was originally equiped with a metal cooled reactor but was soon removed and replaced with a PWR.

Even with the weapons removed there is still a tremendous amount of flammible material on board. I can max out the editor just listed some of them.

If I was a betting person, the insulating material on the hull caught fire. This fire will travel up the sides of the hull catching other things on fire. There are NO 'firebreaks' between decks. In fact, the rafting of the decks give it a place to go between the hull and the deck levels.

At sea it would never had gotten this bad as just about every space is either manned or monitored. Smoke would have been seen and or smelt and they would have jumped fast and hard on it with the whole crew. This started after normal working hours with a reduced manning. By the time it was seen it have already started to spread out of control.

After for closing the hatches and letter it smother out. I do belive that in the end that is what they did. Read here for why I think this.

The above did not come out right in the Cryillic after all. Anyway, they are expressed in kilogram(force) per square centimeter.

http://en.wikipedia.org/wiki/Kilogram-force

It might not be SI but neither is PSI and in any case that's what they are using.

Seth8530 05-26-12 08:27 PM

Well kg is part of the SI system, it is just not a force.. Whoever wrote that should correct that.. BTW where is that page in Cyrillic, might be that I can read it.

The insulation was a foot thick in sonar on a boomer 41 years ago. I use to stare at it six on and twelve hours off, plus everything is wrapped with something if it's a pipe.

Now they are thinking about scrapping her, just thinking so far.

I hope they can cut off the burned part and replace with a 688 going out of service. Soon there will be no more 688's at least use her for training.

That meant that you would not get hit with a 600 kilo warhead but the shockwave from a 500 kiloton one. The number of bulkheads will not mean squat then.


Thanks for the explanation. It makes sense. :yeah:

I imagine that in modern submarine warfare, there will not be the prolonged depth charge battles like in WWII. I would anticipate that submarines are in one of two states.

Undiscovered
Dead.

I agree that once your sub is located having 2/4/6 watertight compartments would not make much difference.


Of course having more compartments might help in an accident, but in war there are always trade offs.
