Loss of state-of-the-art vessel in May or June is setback to Chinese push for naval parity with US
China’s efforts to achieve maritime military parity with the US have suffered a serious blow after its newest state-of-the-art nuclear submarine sank in a dock, American officials have confirmed.
The incident happened last May or June at the Wuchang shipyard near Wuhan – the same city where the Covid-19 pandemic is believed to have originated – and came to light, thanks to satellite imagery, despite efforts by the country’s communist authorities to stage a cover-up.
A US defence official told Reuters that the Zhou-class vessel – first of a new kind of Chinese submarines and distinctive for its X-shaped stern that aids manoeuvrability – is believed to have been next to a pier when it sank.
It is not known if there were any casualties – or if the submarine had any nuclear fuel onboard at the time, although experts have deemed that likely, according to the Wall Street Journal, which initially broke the story. The submarine was eventually salvaged but it is believed that it will take many months before it can be put to sea.
Not sure about other countries, but America’s submarine force is volunteer. You wouldn’t be forced onto a submarine.
I was on a sub and I chose it because being instantaneously crunched sounded better than starving in a life boat.
Read about the Kursk. Instantly crushed doesn’t always happen. Sometimes you get stuck in a compartment for six hours and slowly asphyxiate.
Would the sensation be similar to being at high altitude without oxygen? There is a Smarter Every Day video from several years ago where the host conducts simple cognitive and motor function tests in a pressure chamber which simulates high altitude atmospheric conditions. Within a couple of minutes of being off oxygen, he’s suffering from hypoxia and is unable to either continue the tests, or to mask up, despite being told the he will die if he doesn’t secure oxygen. Admittedly, it’s incredibly chilling to see the guy rendered so helpless, but, from his perspective, it did not seem particularly traumatic. As I understand it, if he had not had his mask applied for him at that point, he would have lost consciousness and then died in his sleep shortly thereafter. All things considered, not the WORST way to go. Beats getting stuck in that compartment with a leak and eventually drowning.
No, you would suffer incredible pain from being unable to evacuate CO2.
You know how painful it gets when you hold your breath to your physical limit? That’s CO2 building up in your body. Just going hypoxic on its own isn’t painful, the pain is the body’s response to having too much CO2.
Yeah, hypercapnia is fucked. I’m actually testing a small CO2 gas generator (literally just citric acid added dropwise to sodium bicarb with an acid trap and a dehumidifying stage) as a means to kill pests on houseplants and did some reading on the symptoms to be safe. It is unpleasant. It’s not the worst death I could imagine, but it’s shit.
As an aside, the way that CO2 kills bugs is interesting. Basically, the excess CO2 (in the range of 10-80,000 ppm) causes their spiracules (i.e. the little holes in their exoskeletons they use to breath) to stay open. This causes them to lose moisture until they die of dehydration (usually in a matter of hours). All this happens long before they asphyxiate or suffer from any sort of acidification from the CO2. It’s a bit fucked up, but all other means of getting rid of the pests on my partner’s houseplants have failed.
It’s not the lack of oxygen that will kill you, it’s the build up of carbon dioxide. And carbon dioxide asphyxiation hurts the entire time.
You’d think someone would’ve invented carbon livoxide by now. What are these chemists even doing?
