Wow only 2 minutes from life to death. very fast.

I have heard of this happeneing with tanks when they are underwater with the breather hoses up. If you block the breather pipe the people die almost immediatly of oxygen starvation.

The Chinese submarine accident in which 70 crew died may have been due to a malfunctioning diesel engine that sucked all the oxygen out of the hull, a Chinese Navy official says.

Investigators believe the crew died within two minutes, after submarine No.361 descended on a training mission two weeks ago. All the victims were found at their posts, and there were no signs of struggle, suggesting that death came upon the men quickly, the official said.

The accident occurred during a training mission on April 16, the official said, but was not discovered by the navy until 10 days later, when the submarine crew did not contact their base as expected. The crew had been instructed to maintain radio silence during training to practise concealing their location.

The Chinese military publicly attributed the tragedy to mechanical failure, giving no further explanation, but Western naval specialists familiar with diesel-powered submarines said the official's account was plausible.

The official said the submarine had charged its batteries from its diesel engine at the surface in preparation for descent. Diesel power is switched off in preparation for descent because diesel requires oxygen to burn, the specialists said.

You live at most 150 years and then you are FORCED to die whether you like it or not.

They are not humans they are Wraiths, serving a lord they can not see, an inhuman master that swallows the lives of all it touches.

Until they learn that their lord sees their lives as valueless, I will not see their lives in any more worth, then their lord.

It's all right, when you are forced to fight them with your blood you'll hate them too.

No one can "love" everyone, some people are just the polar opposites of what others stand for.

Now maybe you can look past the fact that they would destroy your way of life if their leaders simply thought that they wouldn't die in the process.

But I can't see past that fact, they are a dangerous beast, and should be treated as such, just as to them we are the same, and they do treat us as such, but then I guess you never go far from the tour guides at the Great Wall.

Tolkien was actually quite right, with his experiences in WWI, the world is full of Wraiths.

People who have no morals themselves, who will stand up not for their beleifs, but the beliefs of their "masters". And from this has come, Nazism, Communism.

And when America tries to put down these "dictators" these Saurons, the rest of the gebbeth-like world comes to their aid and say we are the bad guys.

Of course, Evil does not rule until by Good's own hand, does Good slay it's strongest, in the name of popularity.

It may not be popular to disdane the Chinese, but the day will come.

From what I can remember Deisel subs used to be the top as far as quite or stealth went. Posted by Advisor

Very true. In nuclear subs, you have to have pumps running at all times to create a constant coolant flow over the reactor core (or risk a meltdown), regardless of if the sub is moving or attempting to bottom out and be totally silent. Nuclear reactors are not readily started up or shut down with the flip of a switch.

Diesels on the other hand run on totally electrical drives when submerged. Due to the lack of constant high volume pumping, and the associated heat radiation disposal problems, (thermal expansion of materials, groaning, creating thermal inversions in the surrounding water and turbulence, ect), a simple large electric motor running the props would be the preferred choice for complete stealth.

If need be, a diesel can simply shut down its motor, litterally with the flip of switch, and essentially be as quiet as possible, disappearing from passive sonar detection systems.

The German (now used by Israel as part of its nuclear deterance system), Japanese, and Swedish diesel/electric boats are considered the best of the crop, and in all standards except for total submerged endurance, can easily hold its own against a nuclear boat.

The main difference between nuclear and diesel/electric boats is that a diesel can now remain submerged for up to a week or two, assuming sparing use of its motor, or can supply high bursts of speed (faster even than a nuke boat) for short periods. The nuke boats on the other hand, are capable of remaining submerged for as long as provisions allow, and can allow fairly high sustained speeds.
