Why Do Submarines JUMP Out of the Water Like THIS?

追加: 2026-05-07

[00:00:00]A submarine is not supposed to launch out of the ocean like this. This is called an emergency blow. It is used when the crew needs to reach the [music] surface fast. A submarine dives by taking seawater into its ballast tanks.

[00:00:13]To rise, that water has to leave.

[00:00:15][music] During an emergency blow, high-pressure air blasts into those tanks. The air forces seawater out in seconds. The submarine loses weight [music] fast. Then, it starts rising hard. Not like a normal surfacing. More like the ocean is thrown back up. It can look out of control, but in that moment, control means getting back to the surface. Would you pull the emergency blow switch?
