Why do submarines not have windows?

There is no reason to have a window because submarines are submerged almost all the time. Besides, there is nothing to see. Submarines operate in open ocean and stay away from any kind of ocean floor. Using external lights to allow people to look through a window would defeat the purpose of being stealthy.

Can you get out of a submarine underwater?

How do you get out of a submarine when it’s in water?

How do submarines work?

Basically, there is a chamber in the submarine which has an inner and outer door. Water will enter the chamber, and then the chamber will be pressurized until it equalizes sea pressure. When this pressure is equalized, the outer door may be opened while the inner door remains shut.

How do you open the outer hatch on a submarine?

They put on and inflate their escape hoods and pressurize the chamber then flood the chamber with seawater. They open the outer hatch and the escape hoods provide buoyancy to raise them to the surface. They must close the outer hatch before rising or no one else can use the hatch.
