Here I thought subs served two purposes... undetectable killers to torpedo down enemy fleets before they get in range of our fleet or giant silent missile launch platforms to unleash a barrage of powerful missiles before the enemy can react.

What mission function does a loud fast underwater vessel serve?

Does it say Ocean Gate Titan on it?

China is apparently making advances in laser propulsion for their subs. This is something that has been an idea for over 20 years, but nobody could figure out how to control the detonation wave created by using lasers to turn water into plasma.

Thrust of a commercial jet engine

A research team led by Ge Yang, a professor at the School of Engineering at Harbin University, has now found a way to improve the efficiency of laser propellers using a coating of optical fibers also referred to as underwater fiber laser-induced plasma detonation wave propulsion.

Using this approach, the researchers claim to be able to generate 70,000 newtons of thrust using just two megawatts of laser power. The thrust generated is similar to that of a commercial jet engine.

In addition to generating thrust, the laser also vaporizes the seawater close to the vessel, creating bubbles on the submarine's surface and reducing water resistance. This phenomenon, known as supercavitation, could potentially allow submarines to travel at supersonic speeds underwater.

With everything else going on... why not?
