China is working on an ambitious project, a ‘supersonic submarine,’ using an underwater air bubble, that could travel from China to San Francisco in less than two hours!
Researchers at Harbin Institute of Technology’s Complex Flow and Heat Transfer Lab are developing a new tech allowing submarines and torpedoes to travel at extremely high speeds underwater.

The new method will be based on supercavitation, an air “bubble” technology applied to torpedoes.
Li Fengchen, professor of fluid machinery and engineering, said:
“The team’s innovative approach meant they could now create the complicated air ‘bubble’ required for rapid underwater travel. We are very excited by its potential.”
