Why Don't Submarines Have Windows?

Описание: Why Don’t Submarines Have Windows?
Why don't submarines have windows? The answer involves 450 tons of pressure, stealth physics, and a design choice made in 1863 that never changed.
Military submarines are engineered to be invisible — smooth, silent, and completely sealed. We break down exactly why windows would make them worse at everything they're built to do, and why the Navy actually prefers its crew to be blind.
We break down:
Why 300 meters of ocean depth creates 450 tons of force on a single viewport
How circle vs. rectangle geometry determines whether a hull survives or fails
Why windows create acoustic signatures that enemy sonar can detect
The real difference between tourist subs (which have windows) and military subs (which don't)
How a Confederate Civil War submarine from 1863 set the design culture still used today
Why at 300 meters depth, a window would show you absolutely nothing anyway
This same engineering logic explains why airplane windows have rounded corners, why space capsules have tiny portholes, and why your car tires are round.
