I love how the Emperor named his flagship after Alexander the Great's personal war horse, Bucephelus. It fits perfectly. I've always seen more inspiration from Alexander in the Emperor than any other leader in human history.

Me: "A starship can _never_ be too big, too good-looking or have too many weapons."
Imperium of Man: "Check this out!"

Scale is always difficult, but the Speranza is definitely continent sized in Lore and the Phalanx is moonsized. Our moon has a radius of 1700 kilometres. So it's really, really BiG!

[HardlyGaming]

It's a common misconception that the Legions received only one Gloriana, the Dark Angels for example had I think 3, the Alpha Legion had 2, one for both Alpharius and Omegon and some other legions got more than one. It's one of the biggest holes in the lore that so many of them are never mentioned again, these ships were powerful enough to destroy entire fleets on their own without much effort, you think we'd have heard some lore about them..

The Bucephalus was only a Battlebarge. It would stand to reason that would landed on Mars with it's own gravitic field was, in fact, the Imperator Somnium.

Any source for the 12km figures for the Emperor class etc? I've never heard of them being a different size than the Retribution.

[OFODRUMS]

I feel like these numbers are whack. Look at the Speranza. A single gun on that thing would have a calibre of at least a couple of kilometers, judging by image. A single shot would be the size of a Vanquisher class batteship. I just don't get it .

[locomastero]

I always thought the Flag Ship of the Emperor was the biggest, guess I was wrong.

Videos about each races fleets would defiantly get a watch and like from me.

Now witness the firepower of this fully armed and operational battle station!

[Willehable]

Great video! There are some questions and inconsistencies in here though they are a bit nit-picky as the video is informational and entertaining.

I do wonder about the Gloriana-class. I wonder where you get the information that the Macragge's Honour was the second largest one, after the Invincible Reason. From what I've heard the biggest one is the Iron Warrior's Iron Blood. This is supported by the Lexicanum, where it is described as among the biggest Glorianas, with the Luna Wolves'/Sons of Horus' Vengeful Spirit, Space Wolves Hrafnkel and the World Eater's Conqueror. So neither the Macragge's Honour nor the Invincible Reason are even in this list. Second, it is a bit strange to have two entries for the Gloriana class but with three different versions? The "generic" one, IR and MH? Just include the biggest, the Iron Blood, maybe the generic one too but that's enough.

Also I wonder about the omission of the Abyss-class battleship. They're described as huge, rivals to even the Phalanx (which, you know, take as you will) but aren't mentioned here? I understand fidning specific sizes for them could be difficult but that's true for many entries on this list?

[Oliver-qzkf]

Can someone explain why the Mechanicus, full of many the most genius minds in the galaxy, can't simply take one of the nova cannons or lance turrets off a ship, strip it down and reverse engineer the technology? Are we seriously saying they're smart enough to upload copies of their brains to backup disks, but too stupid to figure out the science behind a large cannon?

[thorshammer]

I wonder how these ships would compare to endgame Stellaris ships and even the Gigastructures mod's ships. The Stellarborne tech would be stuff which can probably surpass many of the things the War In Heaven era had.

Weaponized Quasar beams which will damage hyperdimensional structures of the Blokkats are no jokes. Even to the Necrons this would be insane.

[tjm]

You left out the 3 Abyss class ships built in secret for the Horus Heresy. Yes, they were built by Lorgar in secret, but I think they should still count, seems how that one was able to set fire to Ultramar, and two are still missing.

[quazarKiragon]

The speranza also contains time and void manipulation weapons, being able to yeet a black hole at its target

[muhrichard]

Ramilies are like 40km across actually

[hitjarjarwithacarcar]

You forgot about the broadsword.... the grey knights battle station above Titan. It is supposed to have made the phalanx look small

[Bullet_Tooth]

Where is the Furious Abyss or its two sister ships?

[osloomortan]

Man you forgot Mars. Yes the planet count as a ship, it can move around. They literally build a planet size teleporter. And the canon, the canon ! How many of them did they fit in that ring ?

[girlgarde]

If one were to tell the Imperium of Man that battleships are outdated hunks of metal and that the way to go are aircraft carrier centered fleets, they'd shoot you for heresy after laughing in your face.
