I know that the Enterprise-E was considered one of the largest ships the Federation ever built. And I know that Borg cubes are seemingly much larger than that. What are the largest ships constructed by the Federation and in the Star Trek Universe as a whole?

The largest Starfleet starship to appear anywhere on screen is the upgraded Enterprise-J briefly seen in the episode "Azati Prime". It's described as being "almost 2 miles" in length (e.g. 3.2 kilometers) as compared to Borg cubes which are approx 3 kilometers in length along each edge.

Enterprise-J

The single largest constructed vessel we see in the Trek TV show is the "Voth City Ship" which measures 9 kilometers from stem to stern. Other artefacts that could vie for the title of "biggest moving structure" would be the Whale Probe (70 kilometers in length), V'Ger (78 kilometers in length) or the Asteroid/Ship seen in For the World is Hollow which measures some 320 kilometers in length

As you can see, the interior of the City Ship is sufficiently large to accomodate hundreds of Sovereign Class ships.

Voth City Ship

Within the extended Trek (book) canon, the largest ship mentiones is a "Fury Ship". These are described in "The Final Fury" as being...

"approximately two hundred and eighty kilometers long, seventy kilometers in diameter, and the pylons supporting the pods extend some three hundred kilometers from the center".

Beat me to the Voth. I would venture that the Dyson Sphere from "Relics" would be larger, but am unsure if that could possibly be classed as a ship. I would say no, but others might say yes. –  James Sheridan Apr 20 at 8:44

@JamesSheridan - A Dyson sphere is a "megastructure", not a ship. It's the single largest structure we see in the show if we ignore Q's energy shield. –  Richard Apr 20 at 8:45

What about V'Ger? –  Ian Thompson Apr 20 at 12:50

I wonder if Borg cubes had increased in size by the time Ent-J was built. –  Xantec Apr 20 at 13:33

@sumbuddyx - That's the "energy cloud" around it; en.memory-alpha.org/wiki/V'Ger –  Richard Apr 20 at 13:44

The generation ship (spoilers) in For the World Is Hollow and I Have Touched the Sky is listed as being:

"an asteroid, 200 miles in diameter, that is not in any orbit but follows an independent course through the local star system"

Since the plot involves changing the course of the asteroid, I would say that that qualifies without reservation as a "ship".

Two other contender with less stellar (heh) provenance would be the pre-Director's Cut V'Ger, which was a ridiculous (and ultimately problematic) 82 AUs in diameter (this means that it spreads from Earth to many of our neighboring planets), or the Dyson sphere from Relics, which was two hundred million kilometers in diameter, but arguably not a ship.

In short, there are technological structures in Star Trek that are so large that they no longer resemble our conception of a "ship".

It was the 'energy cloud' around vger that was (variously) 82AU and 2AU wide. V'ger itself was never more than 78 kilometers long –  Richard Apr 20 at 20:08
    
Great answer and you are right that it seems once an object reaches a certain size it becomes a bigger definition than a ship. –  Amir Apr 21 at 20:14

Seems to me that the The Doomsday Machine of TOS is a contender here. Can't find exact numbers, if they exist, however Commodore Decker, from the first ship to be mauled by it says:

"Miles long, with a maw that could swallow a dozen starships," Decker explains that the planet killer uses a pure antiproton beam to carve planets up into rubble. He couldn't tell if it was a ship or a living organism

A cursory analysis ofthese two images would suggest that it's about two and a half miles long. It's not a ship though, it's a weapons system; en.memory-alpha.org/wiki/File:Planet_killer,_remastered.jpg + en.memory-alpha.org/wiki/… –  Richard Apr 20 at 18:11
    
One problem we may encounter is a proper definition of "ship" in the Star Trek universe. I tend to agree with you, but not all people will. –  James Sheridan Apr 20 at 23:31
    
@JamesSheridan - The Doomsday machine is clearly a machine otherwise the episode would have been called "The Doomsday Ship" ;-) –  Richard Apr 21 at 10:39

Are drones airplanes? Decker couldn't tell if it was a ship or a living organism, see quote. He didn't mention machine as a possibility. Of course, all ships are machines. –  Wayfaring Stranger Apr 21 at 11:52
    
@WayfaringStranger: not necessarily true. See the TNG episode "Tin Man" for an example. Hence my issue with defining a "ship" in the Star Trek universe. –  James Sheridan Apr 21 at 12:29

Balok's ship (the Fesarius) appears in "The Corbomite Maneuver"

Spock says;

SPOCK: Reading goes off my scale, Captain. Must be a mile in diameter.

but it looks a hell of a lot bigger than that when the TOS Enterprise is shown in the foreground.

It's difficult to judge scale but it's certainly huge. –  Richard Apr 21 at 10:38
    
That's what she said. It certainly appears larger than most Star Trek vessels. –  James Sheridan Apr 21 at 12:30
    
Given that the length of a constitution class vessel is 289 meters (~0.18 miles), I'd say Spock's figure seems fairly reasonable. –  ValekHalfHeart Aug 5 at 6:33
