Scientists at China's Harbin Institute of Technology are "a step closer to creating a supersonic submarine that could travel from Shanghai to San Francisco in less than two hours," reports The South China Morning Post. The scientists have reportedly succeeded in replicating an air bubble that would allow vehicles and projectiles — such as a torpedo — to travel more quickly through water, which produces much more drag than air.
In theory, a supercavitating vessel could reach the speed of sound underwater, or about 5,800km/h, which would reduce the journey time for a transatlantic underwater cruise to less than an hour, and for a transpacific journey to about 100 minutes, according to a report by California Institute of Technology in 2001.
