Super sonic subs in US Navy future?
The design looks more like a rocket ship underwater that keeps a constant air bubble that allows the ultra fast speed. It is based on the design the soviets used for a very fast torpedo. The subs could cross the Atlantic in about an hour and the Pacific in about 100 minutes. China is also developing similar subs. The subs would certainly revolutionize naval warfare.
US Navy is developing 'supersonic submarines' that could cut through the ocean at the speed of sound using a bubble
Researchers at Penn State Applied Research Laboratory are developing a new system using a technique called supercavitation.
