ITT: /k/ makes a space gun

Regular rounds have an oxydizer included in the mix. Normal ammunition works in a vacuum. The real problem is recoil buildup and most importantly heat dispersion.

Any current effective gun with a decent cooling system to radiate all that heat.

There you go broseph.
Pic obviously not related.

>>30123448
Go look up how guns work, then come back. The only issues would be overheating, but even then, radiative in -271C would compensate.

Hypothetically let's pretend they don't, so we have to create a new form of ammunition that will work in space without overheating the gun

The discussion would be better if we focused on fixing the cooling issue instead of dropping something that already works because you don't like terran bulets.

Go with a gyrojet then, we just eliminated the cooling issues with the gun. Also it's been done already, awesome right? We Spacemuhreen now.

>>30123565
What about the issue of physics? Each time you fire a weapon it will push you backwards. We need to some how prevent newtons 3rd law from acting or I should say reacting upon us

>>30123603
Eh, something like this? >>30123480

>>30123603
Have the weapon linked to a thruster system on your back, once the weappn is fired the thrusters give an equal foward thrust

>>30123621

not enough in the budget for that, we'll need to rig some sort of reverse-gun to go off in the opposite direction

>>30123603
That issue does make sense but only on very specific situations that are most likely never going to happen, for example the space operator being literally floating in space without no cable or holding any of the handle bars of the structure he's operating in.

Also recoiless rifles are a thing which could be used, though as I said, as long as he's holding something with a huge mass, aka the space station for example, he's not really going to fly around by the recoil of a rifle.

>>30123448

modern ammunition contains it's own oxidizer and works just fine in space. not trying to be a dick, but you really should look stuff up before making a thread. heat dissipation is problematic too (as others already said).

>>30123642
Well when you fire the weapon on a low gravity planet like Pluto or something the recoil is still going to fuck with you, also is the gas giant flammable? Would we be able to create a second sun in our solar system by firing rockets at it? Would haf be the space equivalent of Hiroshima and Nagasaki?

>>30123473
Probably need to come up with a lube film to prevent vacuum welding of bare metal surfaces in contact with each other. A silicone base might work.

>>30123603
Gyrojet rounds are miniature rockets. You're not getting a lot of rearward impulse with those. Put a muzzle brake on the gun to compensate for the impulse you do get.

plasma
>wort wort wort

>>30123900
Doesn't plasma have to be gas that's heated up? How would that work in the sub zero temps of space

>>30123448

Magazines contain a charge of high pressure compressed gas and small tungsten darts or small hunting type pellets.

Gun contains mechanism for loading and discharging using the gas though valves or whatever.

the idea was to use lasers beams to burn holes in space suits.
Although we can always use compressed air or make cartridges airtight.

>>30124000
the density of particles in space (near perfect vacuum) is so low that radiation is the only real way for something to go down in temperature. in space theres almost nothing but radiation to "carry" heat, so even if its almost absolute zero in space, it doesnt really matter because theres almost no material there

that wouldnt work or wouldnt work well in environments with an atmosphere like a pressurized space station or earth

>>30124111
>poking a hoke in space suits

Better idea

>SPACE JOUSTING

We don't really have to worry about the recoil, just tape two guns together facing opposite directions and fire them at the same time so you don't go spinning off into who knows where. Problem solved.

Ejecting shells backward ? And make them flying fast enough.

What happens if you miss your target.

The bullet would fly indefinitely.
Perhaps some micro charge to disintegrate the bullet if it goes to far

>>30124447
why bother, it will just fly off into some random orbit with all the other craps that floating out there.


>>30123448

Regular small arms ammunition isn't going to be super dangerous to a space craft since they have to be designed for impacts with small asteroids moving at relative speeds of several kilometres per second.

You need to step up to artillery pieces at least to be effectual, unguided ammunition is stupid as well since you may as well just use a guided missile given the cost of transport to orbit is going to vastly outweigh the projectile cost.

In all seriousness a small (or not so small ) nuclear warhead would likely be the best bet for payload, orbital dynamics is actually pretty fucking retarded when you get down into it and getting close enough when your opposition is trying to avoid you is pretty hard.

>>30123546
Regular ammunition would work reasonably well, especially considering the brass case is a useful mechanism for removing significant amounts of heat and providing good insulation as the Krauts found out when making the G11.

Coil gun and 3mm flechetes

>>30124272
In that sense you would be shooting yourself

Actually I just looked it up, technically there is definitely enough hydrogen gas to create a blast on Jupiter that will creat a small star, however there wouldn't be enough oxygen to combust said hydrogen.

>>30125408
No there isn't, you are retarded. Also oxygen is irrelevant to stars as they rely on nuclear fusion not chemical reactions.

Guys, please stop being retarded.

The vast majority of sphess combat will probably be like a more autistic submarine warfare but with tac nuke missiles instead of torpedoes.

Actual combat between individuals will probably only occur inside space habitats and ships. For that subsonic rounds firing frangible projectiles will probably work.

Or, you know, nerve gas.

>>30125470
Ausfag, just government rape. Turn back the boats

Americans can't really talk though, they might win in gun laws and a few other areas but in all honesty it is like your government makes a national sport of violating your constitutional rights and then playing endless legal games to avoid ever having to stop.

>>30125484
I normally use /k/ when the Amerifat children are asleep, but work shift work so am currently awake early in the morning in my country. Honestly the really retarded shit only comes on during American children awake at home times (weekends and school holidays).

>regular small arms ineffective
If you're trying to kill ships, you would need more mass and velocity but killing astronauts would be simpler.

>use guided weapons
again probably against ships but guided weapons can always be spoofed, it would be nice to have a backup weapon for combat at < say 50 km. For antipersonnel, guided weapons become to complex and cumbersome.

>nukes
Nuclear weapons become largely ineffective outside of the atmosphere especially against ships hardened against radiation, which they all would be. Damage in space combat will most likely be all kinetic penetrators and lasers.

Space debris can be a real hazard. See Kessler Syndrome.
