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 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.’
