Can a bolter work underwater?

im retarded , google autocorrected it to Aeronautica. Thought there was an article about the Aquanautica imperialis

Yes, but it requires special ammo.
On worlds that are mostly/entirely covered by ocean, that you wish to conquer. There are many aquatic worlds where huge fleets of ships sail the surface and dome-cities litter the sea bed. They are often used as agri-worlds, herding vast shoals of edible fish around in breeding cycles, then harvesting and exporting the protein.

Power armour functions perfectly well underwater since it's pressurised and contains it's own air supply. Though if you want to swim rather than walk, you need an attachment rather similar to a jump-pack. During the Great Crusade, marines fought to liberate aquatic worlds from xenos regularly. The Death Guard were known to be rather good at it, because the ponderous nature of battle underwater suited their tactics.

Land Raiders are also completely amphibious, capable of driving along the seabed. Many a warlord has been surprised when a column of tanks rose from the waves along an unguarded flank. Other (non-titan) vehicles in the Imperial arsenal are in general only moderately amphibious, capable of fording small lakes and rivers. Of noticeable exception is the Chimera, which (after preparation by the mechanicus) can float and is perfectly capable of crossing a sea on the surface.

The PDF on such worlds are often very accomplished sailors, and will often tithe a Navy to the Imperium, to do battle on the seas of other worlds. A Naval (space) transport carrying a Navy (water) is a thing to behold, with frigates stacked up like wood while they await releasing in the enemy ocean.

There was a battle where the space Wolves fought the tau in their undersea bases by using modified land raiders and terminator armor. Didn't mention if they used bolters but isn't the whole point of the bolters being the primary weapon that they are extremely versatile and able to be used in just about any environment?

Any watercraft used in war is probably under the local PDF's service.

There was that time some black templars walked across a ocean floor to fuck up some algae farms or something

Bolter rounds are already self propelled.

Yes. and depending on the source it even gets fired like a normal bullet, leaving a shell.

Yes.

In the recent SW codex is stated how a great company fought the tau in the depths of an oceanic world, pitching terminators against crisis suits in both ranged and melee desperate combat

It ends with the SW smashing the frail underwater domes of the tau, flooding evrything and forcing the xeno to retreat

Bolters have been wholly firing 2 step ammunition for decades now. Not shitting on you in particular but it's really mental how many people that are into 40k don't understand how its most iconic firearm works. It's even one of the few that actually make sense based on modern science.

Man, this thread made me wish for chaos space marines wearing old diving suit-like power armor and showing octopus mutations

SA armor is based on old diving suits.

Heretics pls purge self

I knew it. I had the hunch that such thing already existed, but I forgot where

It's because a ton of 40k fans, especially those who primarily only play the TT, learned the lore in whatever edition they started playing in and have not looked at the lore since.

I imagine there are certain patterns which do, employed by civilian enthusiasts and certain marine chapters who specialize in water ops.

I knew i was forgetting something.

I'm making a SA regiment that is from an ocean world. Some people probably have heard me talk about Mariana III already.

I can confirm that there are specialist underwater marines, as seen in this technical document.

My first guess would be no, since gyrojets aren't self aerating and their squat, wide rounds are pretty much an object lesson on how not to do hydrodynamics. In space, the internally aerated pusher charge would at least allow them to be as effective as a modern firearm, even if the jet doesn't function, but underwater that thing's going sideways before it's gone ten yards. I doubt it'd even spin long enough to arm the charge.

If the Emperor wills it

I love this game so much

No the question is can water work around a bolter?

Not at an imperial wide scale. Local pdf forces would have them for defence.
But the Space navy renders a wet navy obsolete.

Guns don't work underwater, user. It floods the chamber so there's no spark.

...This is a troll, right? People aren't really this goddamn dumb, are they?

Yes bolters would work underwater. Because regular guns can work underwater.

I would assume they'll be using a modified ammo though, instead of a Adamantium tip they'll probably use a version with a Adamantium nose cone designed to vent some of the gas expansion from the jet part of the bolt into a enveloping air bubble to minimize water contact so the bolt can still travel at extreme velocities.

So essentially a supercavitating .75 calibre torpedo.

Swag as fuck.

>So essentially a supercavitating .75 calibre torpedo.

I imagine there are modifications that make them reliably usable in water. The problem is the fluid would interfere with the weapon's feed. It would fire one bolt shell and then the resistance from the water would cause the casing to eject improperly, jamming the gun.

Everything had swag back in the days before the Heresy.

>will the gyrojet work under water?
bolts aren't gyrojets

A few times. I bet you didn't know that landraiders have complete underwater functionality, and have been used in underwater facility raids in the fluff.

...

>one of these reliable weapons that you can drop into water and use afterwards.
That's las weapons. Bolters break all the time, and require tons of maintenance on a constant basis.

What are you basing that on? I mean yeah, las weapons are always going to be many times more reliable than anything gunpowder based, but I've not seen anything in the fluff that depicts the standard, common or garden bolter as anything but reliable. Plus even then when it does come to maintenance, it's hard to say how much of that is superstition and how much is actually necessary.

>Bolters break all the time
no they don't

Chaos marines still use the things, and they've taken them through hell and back. It's the ammunition that's more of a problem.

Yes but only in a round vacum

Yes, due to the round being propelled by a rocket motor, however you would be best off using specialized ammunition.

If rockets do then yes.

Bolt shells have no casing you mongoloid

>bolts aren't gyrojets
How so?

>Literally retarded:The post

...

Bolts are a hybrid projectile. They are started with an explosive charge and are continued by an on board motor.

Which by definition means they're gyrojets, just adapted to remove their biggest design flaw, low initial speed.

STFU OP.
