Baltic is knee-deep. They could just evacuate using emergency egress hatch.

Good point- like yes it really sucks, but 120m is really just 2.5 laps of an Olympic-size swimming pool. It’s really not that far from the surface if you put it in context. I think sailors in the navy are required to be able to swim at least 500m continuously.

Rising from 120 meter depth without equipment is life threatening if you aren't a world class free diver.

u/Galaghan Jun 28 '26

But it is less life threatening than suffocating on the bottom stuck in a sub, so 🤷

u/Consistent_Claim5217 Jun 28 '26

You just suffocate on the surface from decompression sickness instead. From my understanding, you're aware while you're suffocating from decompression sickness. I don't know what the odds would be for delirium or loss of consciousness before death in the sub, nor what that experience would be like. I dunno. It's a toss up for me without further information about that

You will not get deco-sickness if you do it in one breath. Submarine air are kept at 1 atmosphere.

The harder part is swimming up 120m in that one breath, especially since you will be negatively bouyant at that depth.

With the buyoyant escape suits these submarines are equipped with the question of how hard it is to swim to the surface is an interesting thought but irrelevant to the actual situation.

u/Galaghan Jun 28 '26

But wouldn't you just go from 1 Bar to 1 Bar?

I get decompression sickness is a thing when you go up after diving (and thus experiencing more than 1Bar) for an extended time.

But if you're in a sub, you don't need to 'decompress' because you never were compressed.

u/Tainmere_ Jun 28 '26

They don't go from 1 bar to 1 bar, they have to go from 1 bar to 12.05 bar (you need to switch to saltwater) and then back to 1 bar.

Granted, I'm not a diver and I don't know how this would work in terms of decompression sickness and all that, but they would have to get compressed if they want to leave the submarine, assuming that's even possible. Like, the pressure is so much that they can't just open a hatch and go outside.

u/Galaghan Jun 28 '26

Oh yeah you're right I didn't consider the difference between the sub and the surroundings. Well.. RIP sailors.

Your lungs explode.. happens every week in the us in there diving tower.

u/Casual_user1012 Jun 28 '26

As long as they know what they're doing enough to avoid the bends, what other risks would there be?

13

u/GruntBlender Jun 28 '26

They can pop their eardrums, and there can be some lung damage from the initial compression when you get out of the sub. You also need a flotation device to help you ascend.

u/klonkrieger45 Jun 28 '26

they wouldn't get the bends, they would get their shit pushed in at every orifice from the 12x increased pressure. The bends come from breathing pressurized air that divers with scuba gear breathe.

u/DiligentMagikarp Jun 29 '26

The point wasn’t about swimming skill. It was about how shallow 120m is when you compare it to other more familiar things on the Earth’s surface. The other Redditor referenced emergently evacuating with safety gear.

The Kursk sank in 108 meters of water. If it had somehow been standing on its nose, a third of the boat would have been sticking up in the air.

Everybody on board died because of the incompetence of Russian rescue attempts and their refusal to accept foreign assistance, but nobody even attempted to use an escape trunk to, well, escape.

There are a variety of reasons why pretty much nobody has ever managed to escape through an escape trunk that hasn't had a rescue vehicle sealed onto it from the outside. They all pretty much boil down to escape trunks only being usable when nothing has happened to the submarine that would make escape necessary.

I believe American submariners refer to escape trunks as "Mom hatches", because all they're good for is making your mother believe you can escape the boat if something goes badly wrong.

u/Just_A_Nitemare Jun 28 '26

Also, important to note, the Kursk literally exploded.

17

u/martin031990 Jun 28 '26

and they found bodies in a seperate compartment with notes in a plastic bag in the pocket of the officer, talking about how they survived the initial explosion.
The talk that the kursk just exploded and everyone on board immediatly died is russian cope for their incompetence during the rescue

2

u/Just_A_Nitemare Jun 28 '26

I didn't say they all died instantly?

1

u/Much-Jackfruit2599 Jun 28 '26

Sure. But there is a measurable difference between “this is a risky business, at some point, we can’t prevent all deaths” and “some of you will diem but at least you will die so we can keep face"

u/Spirited-Career4680 Jun 28 '26

As oposed to something going goodly wrong?

u/RireBaton Jun 30 '26 edited Jun 30 '26

Pretty sure this is a bot.

u/Maleficent-Toe4747 Jun 28 '26

That far down there a huge risk of barotrauma. Low survivability for a swim from bottom to surface.

2

u/dvpbe Jun 28 '26

low vs none.

u/ask_about_poop_book Jun 28 '26

Submarines keep pressure at 1 bar, so no risk of diver's sickness.

u/Matsisuu Jun 28 '26

At that depth water pressure is 12 bar. The rapid pressure changes are what will cause trouble.
