China's Future Submarine Could Go The Speed Of Sound

Supercavitating Submarine South China Morning Post The submarine of the future may come to America in a super fast bubble, traveling under water. Researchers at China's Harbin Institute of Technology developed a new concept for submarine "supercavitation," where an underwater vessel creates a pocket of air around itself. Inside this bubble, the submarine can travel much faster without friction of water creating drag and slowing it down. Theoretically, a supercavitated vessel using rocket engines...
