Futuristic Chinese ‘supersonic’ sub could reach US shores in under two hours



Traveling from Shanghai to San Francisco in under two hours may sound like a fantasy, but China believes it’s figured out how to design an underwater vehicle that can make the idea a reality.

More worryingly, though, is the possibility that the technology will be used to develop even more dangerous weaponry.

According to the South China Morning Post (SCMP), the super-fast technology was developed by scientists at the Harbin Institute of Technology, and would allow underwater submarines or torpedoes to hit the equivalent speed of sound under water – about 3,600 miles per hour.

The idea is based on the old Soviet concept of supercavitation, which involves creating a large air bubble around an object so that it could avoid facing too much friction and travel through water quickly.

Professor Li Fengchen said that when the vessel hits the water, one of its mechanisms continuously sprays a “special liquid membrane” all over the object’s surface. This membrane eventually wears off, but by the time the vessel reaches 46 miles per hour, it’s going fast enough to enter supercavitation state and generate an air bubble capable of helping it cover previously unknown distances.

"Our method is different from any other approach, such as vector propulsion," Li told SCMP. "By combining liquid-membrane technology with supercavitation, we can significantly reduce the launch challenges and make cruising control easier."

In theory, this means a trip across the Pacific Ocean would take only 100 minutes, while a transatlantic voyage could be undertaken in less than an hour.

Despite the claims of progress, Li added that there are still significant hurdles scientists have to overcome, such as creating precise steering controls and an engine strong enough to power the whole operation.

Many details surrounding the technology remain unknown, since the project is still categorized as a military secret. Supercavitation could still be used to create fast-moving torpedoes and other weapons, and the US, Russia, Germany, and Iran are all working on the same issue.

Still, Li said there could be ways to use the breakthrough to benefit more than just militaries. It could pave the way for fast underwater transportation, or help create swimsuits that allow for unprecedented mobility.

"If a swimsuit can create and hold many tiny bubbles in water,” he said, “it can significantly reduce the water drag; swimming in water could be as effortless as flying in the sky.”

First it was the commies, then Iran, then al-Qaeda, then Saddam, then North Korea, then ISIS, and now it's the Chinese.

Geez, there is no end to the amount of enemies the USA has!

Hopefully, some day soon people here will realize that the USA's real enemies are those who are out to profit from every war possible by making up all these nebulous "enemies".

Sub guy looks like something out of Jimmy Bond.

Wo Fat ?

Whoa, fat. ?

Would certainly improve food delivery.

The Chinese recently succeeded with two hypersonic missile tests. The second hypersonic missile test of the US Army failed today.

The US is reducing the size of its attack submarine force because the Navy doesn't have the money. The Chinese are expanding the size of their attack submarine forces.

Obama sent a second aircraft battle carrier group to the Western Pacific to try and deal with the Chinese.

The USA is in the best of hands isn't it?

Why put ISIS in there?

I'm going to guess the photo isn't the prototype.

Perhaps the English "futuristic" navy can come save us.

B00Mer I have three words for you. Benzo diaz apine.


F-ckin pretty isn't it. A hydrocarbon bound to nitric salts. Why huff propane?

Ok, am I the only person here who's first thought in reading the OP is:


"How many things is this going to smack into through it's journey?"

Countless sea creatures are going to be a bug splatter on the windshield when this thing flies through the ocean.... other vessels, etc.


I'm not all that concerned to be some seal hugging hippy over the sea life that will die in the process of this thing flying off like a bullet, but I'd imagine that eventually this sub would start to take on some considerable damage.


They talk like the ocean is as empty as the sky or something.

We have some of their subs. No danger to attackers there.

Id be real scared if we hadn't been working on supercavitation for 20 years now.

I can tell you one thing you can take to the bank. That particular sub will never be supersonic anywhere.

Shows what you know. That's a matter/antimatter powered supersub with an unobtainium alloy hull and force fields.

They just made it look like a crappy 1930s-technology shallow diver to lull us into a false sense of security. Clever, those Chinese.

Sound travels at a MUCH slower speed that 3,600 miles per hour. And, this idea of super cavitation has been proven NOT to work, repeatedly.

Just because some outfit claims something, does not make it true.

It did say the speed of sound underwater, though they didn't specify the depth. The speed of sound varies with the medium.

Is this about right, one nuclear explosion to create the bubble and then 2 such explosions to 'slow it down' and you won't feel any jet-lag after dinner that night? That about got it?
