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.

    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.

        I use hydrogen peroxide spray to nuke my house plants. It’s a drastic weapon, but really cleans it out. Just make sure you dilute it or you will kill your plants. It’s pretty much chemo for plants.
