What happens when a submarine implodes?

[CaptainMattJ.]

your death would be instantaneous. You usually are more imploded then you are incinerated

however its often that submarines lose control and sink, in which case the crew would see it coming. they just wouldnt know it when it hits though.

When a normal boat sinks, the water entering the boat would pressurize the hull, causing minimal hull collapse.


Its like a balloon. if you let the air escape naturally, the balloon will deflate, but wont explode. If you sit on the balloon, the pressure would cause it to explode almost instantly, leaving you with no recognizable balloon shape and just bits and pieces.

Except balloons dont come under enough sudden pressure from all directions in such a magnitude to cause it to implode.

Because pressure is all around the submarine, and the submarine is hollow, theres room for matter to implode. if the submarine was one long metal tube it wouldnt implode, or stress at all because theres no forces acting against the pressure.

its actually a pretty simple concept when applied to everyday things. Your more likely to crush a soda can into a very small object then you are to crush a solid cylinder of aluminum.

The reason a vessel doesnt implode when filled with water is because water is the force thats applying stress. Water cannot destroy itself. that, and the vessel now has a lot more backing up the inside in terms of matter
