...but it must've been before I got here. Anyway, a friend and I were having a discussion and I was just wondering.

At some point the IoM decides to invade the galaxy far far away at the height of the Galactic Empire's power. For the purposes of the debate assume that anyone else in the galaxy won't bother the Imperium while their armies are away. How would they do:

1) in space
2) in planetary assaults

For an added twist, how would the IoM do pre-heresy?

Xort · Sep 7th 2004, 9:11pm

On the ground the IoM wins, just beats the hell out of the GE.

In space, the IoM inflicts massive damage on the GE but in the end can't beat them.

Which Galactic Empire are we talking about?

PainRack · Sep 7th 2004, 9:19pm

Name how the IOM gets to the Empire first.

The problem with any IOM invasion of the Empire always boils down to one thing. The Empire can inflict more damage to the IOM, faster than the IOM can inflict damage to the Empire.

Hyperdrive gives the Empire superior mobility, the use of super-weapons means that by the time the IOM captures or destroy two planets, the Empire could had wiped out entire regions.

Are you forgetting that the standard IOM cruiser is 3km long and has more than enough firepower to waste an ISD?

Long it is firepower it is not.

In this case you should listen to Yoda: "Size matters not."

SW ships simply have more firepower per volume... combined with the advantages of instant communication and reliable FTL engines they can beat the IoM in space.

Given that (as per the OP), nobody's bothering the Imperium, it can bring its massive strategic reserves to bear, as they won't be needed against its typical foes.

Which doesn't really help them a lot... it just make the war a little bit longer.

Those reserves consist of (at least) ten thousand ships, including four hundred battleships and "thousands" of heavy battlecruisers.

And besides, its not like an ISD's heavy guns can hit an IoM battleship strafing it at upwards of .75-cee (the captain who gave tht number explicitly stated that was his lowest estimate for it).

Grand_Admiral · Sep 8th 2004, 2:03pm

Couple things here:

1. How many ships does the IoM have in all, including reserves?

2. What era Empire?

3. What are the firepower calcs for an IoM ship?

Some other things:

1. An ISD won't be by itself, so the likely hood of just one ISD trying to hit an IoM ship is minimal.

2. The Empire has at least 10 millions ships to fight, note that those are very conservative. Mid ranges are 300 million ships, and the way high end are 1+ billion.

Dunno. Likely a large amount, since the ones lost in Eye of Terror (300+ Retribution-class BBs and most of their escorting ships) weren't considered crippling losses.

High gigaton to low teraton range, with some weapons reaching into the petaton-range (Nova cannon shells' KE).

Not enough for the GE... even to local sector fleets have a total minimum of 25000 ISDs... we don't even know how many millions of smaller ships ( and a lot of larger ones, Vaders SSD is not a very uncommon ship for the GE ).

Speed doesn't matter in space, it's acceleration what's important... and the acceleration of SW ships is pretty good.

The thing is, those were the forces tht two commanders could pull together for a quiet (relatively speaking) incursion into the Eye that they didn't want the High Lords to know about. Now, moving large chunks of the fleet about isn't conductive to that goal, is it?

Not much compared to mere fighters in 40K, since Lightnings (converted air-breathing fighters, basically) can accelerate up to .75-cee within IIRC 750km. Sabbat Martyr gives their distance from the inbound Chaos ships, I'll have to check that.

MJ12 Commando · Sep 8th 2004, 3:18pm

WHAT THE FUCK? Accelerate to .75 c in 750 km? Again, why do they even bother with weapons? The sheer energies the drive must be putting out should be enough to destroy planets...

Remember, this IS 40K we're dealing with. It may not make sense, but its there.

MJ12 Commando · Sep 8th 2004, 3:28pm

Ah. Yes. In 40K, painting something red makes it go faster. Why should it make any sense?

It's the psionic powers of the Ork people that make the stuff go faster... so it makes sense.

Just "stupid green mind over matter"...

Vanquisher221 · Sep 9th 2004, 1:50pm

As per the OP, this happens during the height of the GEs power. Whenever that might be.

WTF? The estimates *I've* seen were mid-gigaton at most.

I remember 600 Gigaton shells...

then that was not wh40k

Captain Orsai · Sep 9th 2004, 2:34pm

610GT per torpedo low end, and scaled from there, plus the KE of a shell the size of a WWII destroyer being fired at damn-near lightspeed.

I remember that 610 gigatons WAS inclusive KE... and the speed was .3 c

You're misremembering things. Necronlord came up with the calcs, but he 614 TTs low end, using the velocity of the much less powerful bombardment cannon.
