Game changer? Futuristic Chinese 'supersonic' sub could reach US shores in under two hours

August 26, 2014 - 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 exceed 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."
