If successful, researchers believe the submarine will reach up to 3,600 miles per hour. That means that a trip from Shanghai to San Francisco in the submarine will take about two hours, elitedaily reported.
A scientific team at Harbin Institute of Technology's Complex Flow and Heat Transfer Lab is developing the submarine. However, the submarine's technology isn't new: it's based on Soviet ideas from the Cold War.
