Who had the Biggest Ship...

[3D Master]

Everyone knows that the biggest was Balok's ship The Fesarius from The Corbomite Maneuever! -- RR

I'm not so sure, a Borg Cube is the same size order, it's corners might just push it over the edge.

However, there is one ship bigger.

The biggest ship was the city ship of the species descendant from Earth dinosaurs in Distant Origin.

The V'Ger cloud was enormous...the actual "vessel" within was about the same size as DS9.

The D'Deridex-class Warbird is notably larger than the Scimitar. In fact, at its design length of 4,440 feet, it rather dwarfs any of the ships that, like it, we've seen more than once.

Well, whaddaya know... I suppose the Scimitar's impressive wingspan is what gives the impression of mass. I never knew the Scimitar was actually shorter.

Then again, with all that empty space inside the D'Deridex, is mass the same as the "bigger" ship?

Yeah, Scimitar has wide wings, but aside from the main body, she is sorta spindly when it comes down to it. While the unusual double-hulled design of the D'Deridex class does make it tough to model accurately, volumetrically, it still seems to be something like 30 or 32 million cubic meters at the design length. That'd make it a little more than five times the size of a Galaxy-class starship (we don't know quite what it masses, but there's no especial reason to think it would be dramatically more or less dense than multipurpose starships of similar tech level). That's kookily big for sure; Romulans seem to try really hard at everything they do, even if we aren't always sure why.

The Valdore type seems to be just shy of five million cubic meters in volume itself, so while she is downright trim compared to her big sis D'Deridex, she is still larger than any known Federation starship except for the Galaxy class ships. Food for thought.

Thanks! that was most helpful. I suppose the camera angles of Nemesis, where the Scimitar was clearly painted as huge compared to the Enterprise, and the often inconsistent scaling of most D'Deridex episodes led to a bit of confusion there.

The V'Ger cloud was enormous...the actual "vessel" within was about the same size as DS9.

Judging by the length of the Enterprise's flight by the actual physical ship, I'd say V'Ger's ship was a *lot* bigger than DS9.

You're right that the D'Deridex was scaled somewhat inconsistently, and I probably should have mentioned that. I tend to give credence to the design size because 1.) I wrote directly to Andrew Probert to find out just how big the darn thing was meant to be and he was kind enough to answer and 2.) I think most, if not all, scenes allow for this size; we probably got the best look at her in "The Neutral Zone" and there she is as Probert intended, and in later episodes she is usually seen from a distance and could easily still be this size. Offhand, I can't think of any close comparisons that disturb this intended scale too greatly. At a 1200 meter length, she would still be more than 25 million cubic meters in volume, or around ten Enterprise-Es!

Now I was looking at the script of Star Trek: The Motion Picture and noticed the following:

(V'GER THEME MUSIC UP) The Cloud "Aurora" EFFECT
rapidly thinning -- in the "eye of the hurricane"
center of the Cloud is the object which has stunned
the entire bridge crew.

Incredible dimensions, Sir!
... I make it as seventy-eight
kilometers in length...

I don't have the movie handy and am not sure this line made it in (didn't ring a bell), but it is interesting to think that V'ger was intended to be this big. Seventy-eight kilometers would have made it it the winner by a pretty wide margin
