>> No.13408835

Orks have an instinctive understanding of technology and engineering, and a psychic gestalt mind that improves their technology's function just by the fact they believe it should work that way.

The imperium cannot build new suits of terminator armor, but a mekboy can produce mega armor in a cave with a pile of scrap.

Tau can make rail-guns that use electromagnetic forces to fire ferrous slugs with the force to liquify land raiders. Orks can make a gun that shoots a hole in the universe, obliterating anything it touches.

I never understood the logic behind this. Orks reproduce via spores shed during the Ork's life, culminating in a large "spore-splosion" when he dies. Necron weapons dissamble the target at the molecular level. Furthermore, Necrons have shown no hesitation in scouring planets completely of life down to the microbial level. Admittedly, this may be a tactic developed to counter the Ork's reproductive strategy, but we don't know for sure.

>Grim Darkness? Good thing I brought my flashlight!.jpg
A better comparison would be railguns to lascannons, and rail rifles to sniper rifles, Pulse rifle/carbine to lasgun
In each case, I would go ahead and say tau have the edge, but they cost way more than guardsmen on the tabletop, and in the fluff imperium has way more resources to throw around.
If the imperium didn't have bigger problems(eldar, orks, chaos, nids) the tau wouldn't be around right now.
i play tau and orks, but seriously, these arguments are dumb. The Tau and Imperium have different goals. Tau want efficiency, Imperium wants power. Thats why Tau don't have gets hot! on their plasma, but are also not as strong.

>Why doesn't the imperium use railguns? They're obviously better than anything they currently use for punching through armor.

Is that why the Tau had to be saved from Hivefleet Gorgon by the Dark Eldar, a Cadian Regiment and a Necron fleet?

>> No.13409019


An enginseer attached to an armoured battalion can repair, replace and maintain a typical battle cannon fairly easy under combat conditions. The battle cannon does not require a dedicated power supply (other than the tank) to function, and does not have many moving parts.

A railgun is complex, delicate and expensive (for the imperium) and generally not worth it. Also doesn't fit the established method of 'blast everything with high explosive and fill the air with shrapnel'

There's a load more reasons, but other than those the main one is aiming; you have to be pretty damn accurate with a railgun and that's not something the imperium is too good at in terms of optics (and would also prevent indirect fire).

>> No.13409037


>They are highly temperamental and dangerous to operate and Executioner crews are often seen as foolhardy or insane.

You do know that Leman Russes don't have ghosts inside them controlling them right and that the weapon isn't unstable at all and it's just imperial gossip?

Also the Imperium usses bigger plasma weapons on super heavy tanks and Titans, they don't explode either because unlike hand carried plasma weapons they have bigger and better cooling mechanisms.

I seem to remember hearing that the Orks killed off their Brainboyz, and were left with the crazy homicidal Orks. That is to say, the normal ones.

>> No.13409105


It's actually not heresy. The reason lasguns are so heavily used (as are autoguns, mind you. Autoguns see similar usage in Imperial hands) is because lasguns are FUCKEASY to both make and maintain. They're absurdly accurate, and actually do pack a hell of a punch.

A laspistol can cook an organ at 200m with a single round through light armor. A hellgun at that range can bore a hole straight through a man and kill the guy behind him. Long las have been known to one shot chaos marines.

You're going to have to define "nearby"

Also how the MBT stops the crew inside from cooking

>> No.13409122

A railgun needs ammo and power. A lascannon just power. Since you can leave a lascannon power pack next to a fire overnight and get a few shots out of it and the lascannon is well understood enough that the average enginseer can fix anything wrong with one that isn't totaly destroyed it's better for the imperium.

The tau like shiney experimental tech, the Imperium solid tech that won't keel over due to bad conditions or usage.

>> No.13409128

That's what I meant, wouldn't it be easier to master railguns before lasers?

>> No.13409151

If they find a STC maybe.

But their ships already use massive railguns for their weaponry. Lasguns have their advantages over railguns for ground combat, while in orbit, they use a combination of lasers and railguns and gauss cannons.

Only the tank mounted version.

Which is another point. 2 Bozos can fire a lascannon. We ahve yet to see a railgun that does not require a heavy suit or tank.

The imperium has a lot of bozos to give lascannons to.

>> No.13409186

I don,t think anyone tested that(and published results).
But the fact is nuclear proof tank designs were around in 50s (Obyekt 279 or something like that).

I thought it was? Well, it's entirely possible I'm wrong.

>> No.13409207

How something that goes a couple dozen km/s can even be indirect fire?
How can a shotgun be indirect fire?

>> No.13409269

"Indirect fire" is a technical term. Indirect fire means aiming and firing a gun without relying on a direct line of sight between the gun and its target, as in the case of direct fire. Aiming is performed by calculating azimuth and elevation angles, and may include correcting the fall of shot by observing it and calculating new angles.

>> No.13409291

Regular tanks are effectively nuke proof. The heat and blast wave doesn't effectively disable tanks or kill tank crews.
So the U.S. developed neutron bombs. Relativistic neutrons would spray out of those and penetrate tank armor. The tank would be fine. The crew would receive senselessly massive doses of radiation poisoning. They would get a few days to live after the neutron bomb went off in their vicinity.

>> No.13409314

Yep, since the Tau develop technology rather than just recovering and preserving it, they quickly found a way on how to produce plasma weapons with a reliable cooling device.

The imperial plasma guns are actualy more powerfull than the Tau plasma weapons of the same size, but the cooling element is not as effective. Possibly because the adeptmechs mixed up parts in their attempts to preserve plasma weapons.

The result is the often dreaded overheat effect.

By the way there is also a perfectly sensible reason why the Imperium gives lasguns to their soldiers rather than compareable powerfull weapons as the Tau give their basic soldiers.

There are around a few million Tau fire warriors compared to the few billion Imperial Guard soldiers. Equiping them all with more complicated weapons like the Tau is simply impossible to achieve with the human level of technology/production power.

Likewise a Lasgun is far more reliable than the pulse rifle, it's easier to repair, harder to malfunction and ammo can be restocked by putting their energy cells into the sun or next to a heat source. Pulse rifle ammo requires carefull recharging and the weapon needs to be in top conditions all the time.

So lasguns are simply better for the size of the Imperial army and the areas they are used in.

Heck, Gue'vesa are actualy capable of building themself Lasguns out of farming tools the Tau gave them and these are weapons which have the fire power between a M-16 and a Anti-Material rifle.

Read the damn thread. They DO use railguns. Bombardment cannons are giant railguns, and they have a dozen of them per side. The MAC gun is a peashooter compared to these things. A single bombardment cannon can sink continents

The Nova cannon is a Railgun that shoots rounds that has a blast radius of hundreds of kilometers

>> No.13409443

>The MAC gun is a peashooter compared to these things.
Not regular MAC cannons or emplacements, I'm talking about the Super MAC Cannon used on Orbital Defence Platforms. It fires a 3000-ton projectile at .4c, with a yield of ~5,000 gigatons. This dwarfs anything the Imperium has by an order of magnitude.

>> No.13409452

Except infinitely more entertaining to use.

Although, from my understanding, Orks excel the most at Personal Forcefield and Teleportation tech; with their Forcefields easily being the best in the Galaxy while their Teleportation second only to the Necrons.

>> No.13409506


Makes you wonder how they stay in orbit when that thing fires. Those numbers are a case of "MAKE UP NUMBERS EVERYWHERE TO MAKE IT SEEM AWESOME" Forgetting the energy required to fire a 3000 ton projectile at anywhere near a decent value of c, which would make the chaos gods themselves flabbergasted.

Its like how we treat forgeworld armor numbers (100mm of steel), its complete BS.

But if we're going that route. each bombardment cannon is supposed to have an output of around 500 gigtaons give or take. There are a dozen or moreof them on Imperial ships.

Also, its a danm good idea to have a unshielded stationary, gigantic target that can be disabled with a single salvo from light minutes away. And yes 40k space combat tends to be resolved from hundreds of thousands of kilometers away.

Not sure why the covenant thought that slow moving plasma would work well in space, but okay.

"Shot firedoooohh shit there goes Middle America"

Seriously, a thruster that could compensate that kind of momentum would probably be bad news for anyone on the planet.

Actually, the codices say that a Tau hammerhead railgun bores right through Imperial tanks and liquefies everything inside by pulling it right out the far hole.

Obviously if a railgun hits a weak point and penetrates through then it'll cause massive damage, but a hit from head on hitting a mass of steal at an angle or at a corner just rips out a chunk of armor.

A gauss weapon (coilgun) accelerates a magnetic projectile through a series of magnetic coils by simply turning those coils off as soon as the projectile passes through them.

A railgun accelerates a conductive, not necessarily magnetic projectile by creating an electric current through two rails and the projectile. The projectile experiences a Lorentz force because the current running through the rails generates an electric field and there are electric charges moving though the projectile. pic related.

Main difference is that a coilgun slug needs to be ferromagnetic while a railgun slug only has to be conductive.

At some rate, 40k tech makes more sense than Covy in terms of ship vs ship engagements.

I mean seriously, 20 Super Macs around a planet? How the hell do they ALL fire at a Covenant fleet that is approaching on a single vector. How do three or so several kilometer long ships act as a shield for an entire fleet? Did the covenant really just come in one direction and not spread out to rape them with plasma fire? If the covenant are so damn good and awesome at stuff, why not slipspace some corvetts right on top of the super macs, fire a round that slags a single capacitor which makes the entire thing useless and then suicide itself into the gun to blow it up for good measure?

Pinpoint slipsace jumps opens up a massive "why the fuck didn't they do this" hole.

IIRC, the gun sucks the matter of the target in molecule by molecule. It brings in the outer layer first, hence the flaying effect.

Not what the weapon does, but how it works. I recall reading (on a Wiki of some kind, long ago) that the only similarity with how the weapon actually worked was that it used energy/current to propel its "projectile."

>corvetts right on top of the super macs, fire a round that slags a single capacitor which makes the entire thing useless and then suicide itself into the gun to blow it up for good measure?

This was addressed to some extent, as they tried it: after a jump the ship appears to be powered down for a few seconds, meaning no shields/weapons etc and leaving it open.

How long these seconds are, no idea, but it gave the UNSC enough time to realign a Super-Mac (i think) and blow it away.

So then, why not rematerilize inside the MAC gun, they don't seem to have trouble sacrificing ships like that.

And aren't these super Macs supposed to be huge? How did they even aim at it so fast. And why for a corvette, should be aiming at more important targets.

Actually what they could do is accelerate a covenent ship as fast as they can right at a vector toward a mac gun. Even if it gets destroyed, its still a ton of debris heading toward a very delicate weapon at very high speeds

Mostly, economics. Lasguns don't need ammo, just power. Power cells can be recharged. Guardsmen are dirt cheap. It's just easier to give them lasguns logisticly.

>So then, why not rematerilize inside the MAC gun, they don't seem to have trouble sacrificing ships like that.

It's been somewhat stated that (somehow) something re-emerging from slipspace 'pushes' anything away from the co-ordinates before it emerges.

>And aren't these super Macs supposed to be huge? How did they even aim at it so fast. And why for a corvette, should be aiming at more important targets.

As I said, i'm not sure if it was the super mac that took it out, or if it was the Pillar as it flew past; they do have a stupendous rate of fire though (1 round every three second) and a huge amount of slugs, so they can essentially fill an area with metal. It helps that the slugs they fire can penetrate a cruiser and still have enough momentum to destroy other ships.

>Actually what they could do is accelerate a covenent ship as fast as they can right at a vector toward a mac gun. Even if it gets destroyed, its still a ton of debris heading toward a very delicate weapon at very high speeds

Wouldn't surprise me if it worked, but the sheer impact of a Super Mac on a corvette basically wipes it from existence, and I imagine this would overwhelm any existing inertia (and the resulting explosion would disperse them)

1. What. That is just dumb. And even so, considering they use "capacitors" to fire their plasma weaponry, they should just hold a charge and fire as soon as they get out. And doens't change the fact that if they shift the MAC gun the wrong way while its firing, it would rip itself in half. A very small disturbance can create a massive imbalance.

2. Good god, they much have captured Khorne himself, stuffed a tube up his ass, and started gathering the pure energy he shits out constantly to run something like that. What kind of material are they using that doesn't shatter and melt instantly upon impact.

3. Inertia overall maybe, but you still have the pieces flying that got ejected from the ship upon impact

No. They are manned by actual marines.

Land Raiders and Predators are manned by Marines. Space Marine ships are heavily automated and most of the non-servitor crew are Chapter Serfs. BFG Armada says:
"Unlike the vessels of the Imperial Navy, a Space
Marine ship has a relatively small crew. A Space
Marine is far too valuable to waste in manning a
gun or watching a surveyor screen, and so only
the officers aboard a vessel are likely to be
Space Marines, as well as the few Techmarines
who oversee the engines and perform other
mechanical duties. Almost all the ship’s systems
are run and monitored by servitors; half-human
cyborgs who are wired into the vessel’s
weapons, engines and communications
apparatus. There are also a few hundred
Chapter serfs to attend to other duties, such as
routine cleaning and maintenance, serving the
Space Marines during meal times and other
such honoured tasks. These serfs come from the
Chapter’s home planet or the enclave they
protect, many of them Novitiates or applicants
who have failed some part of the recruiting or
training process. These serfs are fanatically loyal
to their superhuman masters, and indoctrinated
into many of the lesser orders of the Chapter’s
Cult. Although human, they still benefit from
remarkable training and access to superior
weaponry than is usually found on a naval
vessel, making them a fearsome prospect in a
boarding action – even without the support of
their genetically modified lords."

Also, they have to worry about the rail round you know, from just torching everything inside the vehicle, not to mention the impact itself destroying key components of the vehicle. I mean, I mean, if you look at freeze frame of the Navy's railgun round, you can see that its trailing fire, because just the friction between the projectile and the air around it is causing it to spontaneously combust. And that's just Mach 7. Who knows how fast the Tau are able to push their railgun rounds.

Admech could make excellent plasma batteries and spaceship drives until M35 at least that was when Murder class cruiser production ended.

BFG fluff says that Murder's broadside batteries consist of finest plasma weaponry produced by Adeptus Mechanicus, and that it was the mainstay of Imperial fleet, the predecessor of Lunar class cruiser. The current long-range gunboat cruiser, Tyrant class, is a rare vessel (gamewise more expensive and slower than the Murder), utilizes different sort of technology and the fluff says it is often forced to utilize salvaged archeotech batteries from space hulks or renegade ships to achieve optimal effect.

In game terms it means that the Tyrant with its broadsides refitted to Murder-equivalent power is over 14% more expensive than the older cruiser and moves slower. The characteristic IN armored prow and ordnance weaponry like torpedoes that are less of an energy drain are how Mechanicus compensates for lost technology.

When they started using DPU rounds in Desert Storm, they thought that there were a whole lot of abandoned tanks and dozens of enemies behind the front lines.

Turns out that the DPU rounds passed through the tank, and the impact shockwave shockwave liquified the people in the tanks and dragged the liquified remains out the exit hole with the vacuum pull of the shell leaving the tank.

And that's just modern everyday tank ammunition.

Well that may be an exaggeration but typically a DU penetrator will bounce inside the compartment after penetration so the crew won't look good after that. DU also has incendiary properties so most hits end with a fire/ammo cooking off etc.

That's something of an urban legend.
Sometimes a T-72s ammo will cook off upon penetration resulting in a nicely charred tank. Sometimes it will even throw the turret a bit.
But sometimes the round will just pass through, burning the interior, but otherwise leave the tank intact. From a distance it will look functional.

Also it is toxic like lead is toxic due to it being a heavy metal. The radiation from it is on the level of cancer risk if you slept on it every night for 40-50 years.

Fluff wise the covenant actually did this, after realizing trying to take out a MAC with their ship's weapons (yes the MAC out ranged everything the covenant had) and the Spartans II were making too hard for the covenant to take down the Nuclear fusion generators powering the MACs they finally decided to use their damaged ships as battery rams to take out the MAC stations

Also according to Cortana the Covenant weapons even being more powerful than their human counterparts would be much more powerful if they actually had the Gauss Equations and formulas interpreted right, with the good mention that when Cortana seized on of the Covenant ships she altered their weapons in such manner it became so efficient it dwarfed all other covenant bigger ship weapons.

The T'au can have better gear because they understand their tech, claiming if they had a size comparable to the imperium they would be using lasguns esque weapons is a silly argument. Even china with its massive army isn't using super outdated gear even though it can't match US or Canada and most western powers in terms or tech.

If you know how your tech works and can manufacture them in a manner to arm an army reliably disregard of the numbers you won't be forced to use cheaper outdated shit to equip your army.
