The Navy term is "Silent Running"; when ordered, a submarine crew refers to one of the battlestations rigging bills to "Rig for Silent Running". It tells the crew which systems to shut down or reduce operations on, and all non-essential personnel not on watch or at critical tracking stations are ordered to their racks.
The usage hails from the Fleet Submarine days, when detectable noise was a real issue when dealing with attacking Destroyers of the day. Limited speed, maneuverability, and depth capability required every advantage to avoid detection, and Silent Running was part of that strategy.
Today's modern submarines are quiet enough that they are difficult to detect by anything other than another submarine, and even that's not easy with today's improved Sonar systems. However, being too quiet is also a dead giveaway in the ambient noise of the ocean; a trained Sonar crew will notice an acoustic dead spot moving through the water as well.
The ability to use the ocean environment to its advantage (depth, thermoclines) to hide in acoustic areas of advantage has also made the need for SR almost obsolete.

What is the boat that goes under water called?
the name of a boat that goes underwater is called a SUBMARINE.
How does water pressure affect a submarine?
When a submarine goes farther down in the water, the water pressure becomes greater. If the submarine goes to far, pipes can explode and let in water, or it can implode the submarine
When was sonar invented?
Sonar was gradually developed and improved over many years, but the first operational form of sonar as we now know it goes back to about 1918.
Does the water pressure increase the deeper a submarine goes?
Yes, the water pressure on a submarine increases as it goes deeper.
How long is Yellow Submarine?
Yellow Submarine goes for 2 minutes and 41 seconds.
If a submarine is submerges what is it doing?
When a floating submarine submerges, it deliberately goes beneath the surface - which it is designed to do
Which ship that's goes under of water?
A submarine.
What do you call a ship that goes under water?
A submarine.
What happens to the magnitude of the fluid friction acting on a submarine as the submarine's speed increases?
As a submarine moves more quickly through the water, the fluid friction will increase. The two (the magnitude of the speed and the magnitude of fluid friction) are directly proportional. That means what happens to one happens to the other. If one goes up, the other goes up. And if one goes down, the other goes down.
Who create submarine?
Credit for the creation of the submarine goes to William Bourne, a British mathematician and former Navy gunner. He published his design for it in 1578.
What is a synonym for silence?
quiet silent and it goes on
What do you call an underwater volcano?
