A ‘supercavitating’ submarine creates a bubble of air that encompasses the whole vehicle by ejecting gas through the nose with enough force that it forms water vapor. This greatly reduces drag and allows it to travel at high speeds not possible by standard submarines. Photo: The Washington Post
In the annals of vehicular locomotion, the submarine is the equivalent of the Walkman. It dazzled the masses when it hit, flexing nuclear-tipped missiles that completed the “nuclear triad” of deterrence.
But other technologies soon surpassed it in terms of speed and agility. Now, years later, the submarine may be making a comeback — at least theoretically. Researchers at the Harbin Institute of Technology in northeast China tell the South China Morning Post that they’re hard at work on a s...Read More
