Chinese Scientists Say They’ve Found the Secret to Building the World’s Fastest Submarines

Summary

77% Informative

Researchers at Harbin Engineering University in China propose using laser propellers to propel objects underwater.

The new technology uses lasers as a form of underwater propulsion to achieve not only stealth but super-high underwater speeds that would rival jet aircraft.

While the technology is theoretically possible, it does suffer from a potentially fatal flaw that would make any submarine using it even more vulnerable to detection.

The super sub in our South China Sea scenario suffers from a fatal flaw: while laser propulsion will lead to faster submarines, it will also lead to noisier submarines.

China , Russia , the U.S. , and the other major submarine powers are working to develop a faster way to move submarines one that doesn’t sound like rocks in a pipe.
