Which one wins in a sublight race?

It did a barrel roll because it had like half an hour to pull off that dodge and "only" needed a few minutes.

40k's speeds have similarities with speed in the gundam universe: Things are portrayed as being ridiculously fast only because they're being compared to very very slow things.

A Lightning Fighter for example can hit 2400km/h in the air. For something 38000 years in the future, MACH 1.95 IS PRETTY FUCKING UNIMPRESSIVE. The mass-production R-9 Arrowhead in r-type has an *acceleration* of 208m/s (though it's too old a model to go FTL without something else to boost it in first)

That star destroyer, a giant fucking brick, is still doing something like 975 kph in an atmosphere.

Hell, the 40k tanks are the epitome of "wait that's not advanced at all", having worse armor and general performance than shit we had during the cold war.

How fast are star wars ships and star trek?

Quickest 40k vessel I have seen from any source was 1,600,000km an hour without them having to coax the ship to go faster with game maneuvers. Note that was cruising speed of a raider built for speed and with a history dedicated to speed.

>Hell, the 40k tanks are the epitome of "wait that's not advanced at all", having worse armor and general performance than shit we had during the cold war
I'm calling bullshit. Even ignoring superheavies like Baneblades, comparatively small tanks like the Leman Russ and Chimera are superior to modern tanks.

>Hell, the 40k tanks are the epitome of "wait that's not advanced at all", having worse armor and general performance than shit we had during the cold war.

Those stats have since been retconned. Nowadays they are described as acting as superior to modern tanks, especially when it comes to reliability. Leman Russes are considered "workhorses" because they can literally run on anything flammable and viscous enough to get in the fuel tank while also being durable enough to survive environmental hazards our world doesn't even have. Couple that with its incredible movability, and it's a fantastic tank.

Those old numbers are no longer canon.

*incredible modability, not movability.

According to the TNG technical manual aka shit taken straight from the series bible by the people in charge of the tech part of the show (and using TNG because it's actually fairly consistent compared to Voyager and so on):
In the impulse drive section:
"High impulse operations, specifically velocities above 0.75c,"

So in excess of 809,439,637 Kph/ 502,962,472Mph

"At times when warp propulsion is not available, impulse flight may be unavoidable, but will require lengthy recalibration of onboard computer clock systems even if contact is maintained with Starfleet navigation beacons. It is for this reason that normal impulse operations are
limited to a velocity of 0.25c."

Which is about 269,813,212 Kph/167,654,157 Mph for just pootling about.

Shits fast yo.

These values are totally meaningless because it's space we're talking about. Any ship can accelerate to a high fraction of the speed of light given sufficient time and unlimited fuel.

The relevant factor is their rate of acceleration and for how long they can accelerate.

So in the case of 40k, forever since they never discuss needing fuel.

The engine just needs to be installed and turned on and it runs until the ship is destroyed. Some ships have had their crews slain/kidnapped and they kept going until someone runs into them.

"During the early definition phase of the Ambassador
class, it was determined that the combined vehicle mass of
the prototype NX-10521 could reach at least 3.71 million
metric tons. The propulsive force available from the highest
specific-impulse (/s) fusion engines available or projected fell
far short of being able to achieve the 10 km/sec2 acceleration
required. This necessitated the inclusion of a compact spacetime
driver coil, similar to those standard in warp engine
nacelles, that would perform a low-level continuum distortion
without driving the vehicle across the warp threshold. The
driver coil was already into computer simulation trials during
the Ambassador class engineering phase and it was determined
that a fusion-driven engine could move a larger mass
than would normally be possible by reaction thrust alone,
even with exhaust products accelerated to near lightspeed."

So about 10 km/sec2, given they managed to build bigger, better impulse engines to move the overly fat brick that is the Galaxy Class.

>Some ships have had their crews slain/kidnapped and they kept going until someone runs into them.

Not just that, some of them literally continue their missions because their Machine Spirits are so old they're virtually alive. Most vessels have a "mind of their own" to a greater or lesser degree, given how incredibly complex their machinery is.

IIRC there was a frigate that literally pulled into port at a way station with no crew whatsoever, even though it completed all the necessary "handshaking" and docking procedures. The Navy had no idea what to do (because ships are "smart," but not THAT smart) so they disengaged it from port and blew it out of the fucking sky out of an entirely justifiable fear of Warp-fuckery.

You also have DeathWatch kill ships that are full sized battlcruisers that no one can detect, shooting rockets into system that wipe planets of life that can not be detected. All while being fully automated, warp jumps included with no corruption.

Can you imagine being the machine spirit of that ship? Like, holy shit that's depressing.

>Spend untold years slowly developing sentience/sapience/ego/whatever
>Know the personalities of the navigator, the captain, and the entire bridge crew
>Grow attached to the entire crew as you watch them go about doing their crewy things
>Get sent on mission, For_the_Emprar.mp3
>Watch helplessly as crew is slowly wiped out by threat you can't counter
>Beg the guy who's basically wired to the ship to turn around, knowing that it's in vain
>Pilot guy dies, all alone
>Fuck this shit, loop For_the_Emprar.mp3 because you're a good little machine spirit who loves the Emprar
>Come home after completing the crew's mission
>Get blown out of the sky

Just imagine if your are fighting something like the Stryxis as that machine spirit/ship.

You would feel a weird tingle as the humans freaking out right before you notice on one is left. Ghost weapons are fucking insane, bypassing all armor and just kill crew.

Yep.

Too be fair, though, it's also 100% possible that an Event Horizon scenario happens and it becomes possessed by Daemons, only to reveal its dark nature at the last minute.

In M41, you legitimately cannot be too careful.

Or Iron Men.
Or aliens, or alien influence.
There's so many horrifically fucked up things that could be behind it that a ship can encounter both in and outside the warp.

Guys

What about

You guys

What about Space Hulks?

How fast could you go if you were driving a warp-melted mess of ships and rocks a full astronomical unit in length?

As fast as the Daemons, Orks, or Genestealers driving the thing can make it go, and they have a nasty habit of dropping out of the Warp with little regard for speed limits.

There is a space hulk in Rogue Trader that travels fast enough it goes through a system in like a day and is also warp capable with some areas covered by WAAAAGH! fields and Gellar fields.

Orks control it and send out DEldar style raids on planets to have a murder spree vacation before coming back to WAAGH! it up some more.

The 40k ship wins the sublight speeds hard, as they practically move at light speeds when not at warp speed.

Star Wars ships however MASSIVELY outperform both Star Trek and Warhammer in terms of Faster than Light. The movies have characters crossing half the galaxy in a matter of fucking days.

They only have a single ship of that description, and it's smaller than a frigate; barely enough room to accommodate a few vehicles or drop pods in its deployment bays.

Depends on the setting.

Not even trolling It's all about whoever's GMing the battle, and which fandom they're most autistic about.

You could theoretically find someone with encyclopedic knowledge of all three canons' lore and fluff, who hates them all equally, and is willing to stat up all three ships in, I dunno, Traveller or some shit, and then actually run the battle.

But then the 40K fag would just flip the table when he lost, so fuck it, why bother?

>But then the 40K fag would just flip the table when he lost, so fuck it, why bother?
Butthurt warsie detected, tell me, how's that retcon feel bo?

Wonder how fast orks could make the Enterprise go?

>an ork with half a metal grate welded to his brow is busy down in engineering using two grots like defibrillator paddles trying to coax more power out of the antimatter warp core

>he becomes more and more frustrated until the red emergency lighting comes on, telling him the ship is moving faster

Read the final logs of Offensive Bias from Halo 3's Terminal 6 on Legendary mode. An AI's final battle report written after the extinction of its progenitor race, for those who may yet come after.

I'll have the Trekfaggot flip the table, the next time I post the copypasta. Thanks for the reply!

>Shit made up by writers with zero knowledge of physics.

Yeah, he really fell into your cunnin trap there eh brainanon?

>which wins

It's a "tonne of feathers" trick question. Since OP set the max speed, races will always end in a tie.

Have to kinda disagree there.

The Star Trek ships are capped at 25 or 50% c, depending on the writer, that's true. For the sake of argument I'll go with 25% now.

Earth is 8 lightminutes from the sun. That means the Enterprise could make that distance in 24 minutes, destruction by proximity to a star aside.

Pluto is 5,5 lighthours out from the sun. That's 22 hours of travel time for the fed ship. 44 hours from rim to rim, again ignoring the star in the middle.

That's still a good deal faster than anything I've ever read about WH40K craft. Although I have not read everything, and the material is notoriously inconsistent. And I have not ever read about 40K cruisers doing an infinite acceleration move, they generally seem to fly non-newtonian and require the drives to provide thrust to remsin in motion.

In short, the Mars doesn't even win a long race.

No argument about the Star Wars ships though. Even their fighters aren't faster than current sports cars.

In Shield of Baal, it was said that a C'tan shard flew in space in speeds were above the speed of any Imperial ship.

As we know, C'tan shards have no real way to acculturate. They have no thrusters, no engines, nothing, yet they beat Imperial ships in space travel.

What does that mean? Imperial ships are woefully slow outside of Warp travel.

alternatively, stargods with eldritch powers, up to and including manipulation of matter, space, and time, can go incredibly fucking fast because they want/need to

...

As and say, the old armour has long been retconned - they are far, far superior to anything we have.

Speed though, is another matter - 40k tanks are slow, though this matters less when you're supporting an advance with non-mounted infantry and artillery, or are city fighting, or have easy access to shuttles and aircraft that makes transporting tanks trivial.
Given that all of these are pretty common things, the incredibly slow speeds (about 55kph for a Land Raider, and that's faster than IG tanks) are somewhat more excusable

As for the ships, they all move at the speed they need to for the plot.

Somewhere a picture is floating around comparing Landraiders to Abrams
>inb4 'but muh spess metals!'

It's like you morons don't actually keep up with the fluff.

Mars is faster, Imperial cruisers have been directly stated to have a "combat speed" of 75% C.

And the hypespace/warp jump race too.

The Emperor Protects.

Their suspension is garbage though.

The Chimera really, REALLY isn't, considering it can be pierced by the .50 cal in-canon.

Leman Russes have the excuse that any Leman Russ that dies to something unlikely must have been a "Monkey model" made of standard steel as opposed to the ceramite/adamantine composites it is "supposed" to be made from (disregarding that a modern tank made of the same materials would outperform it.)

>disregarding that a modern tank made of the same materials would outperform i
thats kind of the whole point of the techno-barbarian thing the imperium has going on. They're backwards ideas that work because they can be combined with "relics" from the much more advanced past, in this case bad tank designs saved by crazy good materials science.

It's a perfectly good design for a tractor! Runs on anything, tough as all get out and can push shit around. It was only retrofitted into being a MBT on account of being a really tough and versatile vehicle they had designs for.

Leman Russ isn't a tractor.
You're probably thinking of the Seigfried Light Tank that the Death Korp used instead of sentinels in epic.

Nah, it's just a popular bit of fanon I like.I've heard it parroted enough and it fits the tone of 40k that I forget that there's no actual source for it.

>can be pierced by the .50 cal in-canon

Source?

First I saw of this meme was in an issue of Starlog, way back in the 70s: ANH Death Star vs. TOS Enterprise. The Trekfag writing it pretended the Death Star didn't have any shields at all, so he could have the fat Scottish guy beam a photon torpedo into the reactor.

It was fanboy shitposting then, it's fanboy shitposting now.

Gundams not that fast. The zaku 2 only moves something like 88 kph.

Can you direct me to the source on that?

One of the eisenhorn novels. Or execution hour. Can't remember exactly.

Then I suspect Execution Hour, can't remember any statement about ship velocities in Eisenhorn.
