Underwater Express Submarine Utilizes Bubbles for Speed

Illustration for article titled Underwater Express Submarine Utilizes Bubbles for Speed

Over wonder why the Red October was so damn slow? It is obvious, water is heavy and it takes a lot to plow through it (compared to air, at least). The Pentagon has developed the Underwater Express, a submarine capable of going 127 mph (compared to modern sub speeds of 29 mph, by encasing the entire sub in a bubble. Bubbles can move through the water quicker and therefore cause no drag on the actual submarine. Now if only we could get in a war with a country with a large body of water. Iraq is just too dry.

It's called supercavitation. Apparently the Russians had working torpedoes using the principle in the 70's.
