What exactly IS a "Deep Dive" sub?

[CrazyEight]

I get the idea of Scout, Attack, Transport. But what defines the "Deep Dive" class exactly? What sets them apart?

Last I checked hull upgrades are most of it and deep diver vessel can go 25% farther down then the rest.

In Barotrauma, the Abyss is defined as the layer of the ocean from 1600m depth and deeper, until the bottom of the levels. The pressure there is such that diving suits offer no adequate protection, and even the hull of the submarine take continual damage while in this zone; the deeper the submarine is in the abyss, the faster it breaks. It should be noted, with adequate protection of the hull, most submarines can survive up to depths of ~2000m before flooding. Past these depths multiple walls on the outer layers are advised, and all windows should be replaced with walls. Additionally, heavy ordinance such as Nuclear Shells should be brought in high quantity, preferably filled with explosives.

For obvious reasons, it is recommended to avoid going to these depths at all, much less diving in them.

Critical Depth
Depths below ~2500 are commonly referred to as "Critical Depth", where at any moment, the submarine may spontaneously implode, destroying nearly all structures in the sub and killing most of the crew. The most notable sign that you are approaching critical depth is when all the exterior lights on the submarine begin to flicker, then shatter. For this reason, submarines designed for deep-Abyss travel should always be fitted with exterior lights, as well as extra layers of hull. If intending to explore critical depth, players are advised to move the submarine slowly, as hull breaches occur more often when moving quickly.

Contrary to popular belief, the Abyss does have a bottom - if a submarine goes far down enough, it'll encounter the barren sea floor. However, there is nothing to be found here. The sea floor is mostly useless, as it lies far beyond critical depth, further than any ship will be able to survive unharmed.

While most maps' abyssal depths and critical depths are at 1600-2500m, the actual depth of these varies on the size of the map - if a map forces you to navigate lots of vertical caverns, the abyssal depths and critical depths will be deeper than usual (usually 2500-3500m); whereas if a map forces you to navigate long, horizontal caverns, the abyssal and critical depths will be higher.

That doesn't seem right, me and some friends are at 2300 right now without issue. Did the Abyss Depth change with updates?

[KnEe_GrOw]

If you have gotten any hull upgrades that will allow you to go deeper safely.

[Captain Bart]

Did you bought any sub upgrades?

[CrazyEight]

The rest of the crew says No

[CrazyEight]

We are in the MOD sub CSS Palestar 2 for reference.

[Captain Bart]

Well wierd, possibly update added something new to "deep diver" class

[CrazyEight]

That, or maybe were were on a very vertical map and the critical depth got moved? That last mission we reached 2500 without issue.

[CrazyEight]

ANYWAYS! Back on track.

Deep Dive get a Depth Bonus?
Does that mean other ship classes get buffs too or are those just based on way they are designed?

Because this whole time I thought most Scouts were fast, Attackers had big/many guns and Transports had a weight problem.

[Captain Bart]

Try getting out and in from sub in normal diving siut and tell us if there was presure.

[Captain Bart]

Other ship classes get buffs too, if I remember right, attack subs get more damage for guns, scouts, have buffed engine, cargo have more money for transport missions.

[CrazyEight]

For the longest time I thought they were just designations based on what job the ship was supposed to do. This is good to know.

The wiki article says "This article is outdated".

How accurate are the information from this wiki page?

[Captain Bart]

More or less, but most are accurate enough.

I don't think these have been implemented yet, so far I've only seen patch notes saying the deep divers get a flat class based buff. The vanilla transport class subs have mineral scanners installed but that's the only bonus they have right now. It looks like[trello.com] transport subs being able to get more money from cargo missions may be implemented soon though!

I hope you are enjoying it!
