Does Star Wars have some of the largest spaceships in sci-fi?

Does Star Wars have some of the largest spaceships(and some of the most powerful) in sci-fi?

Maybe I just haven't seen/read/played enough of sci-fi, but in the vast majority of fiction I've encountered, even the largest of capital ships are usually limited to a few kilometers in length and/or width.

Some of the ships in Star Wars, on the other hand, are pretty damn huge. Those Super Star Destroyers/Dreadnoughts can be up to around 20 kilometers in length! And then there's the really big stuff like the Death Stars and that Sun Crusher thing. On top of it all, all of them seem to have the firepower to match their impressive size.

So what are your thoughts? Maybe some of you more knowledgeable types know of fiction where starships are consistently bigger(and more powerful) than those in Star Wars.

Well the Suncrusher wasn't a big ship it was a single seater, it was just invinceable, and could make stars go supernova. Oh and

"Small" Ships.

"Medium" Ships

"Large" Ships

"Huge" Ships.

Probably outdated.

Now I'm not sure if this counts as "sci fi", but Galactus has a space ship the size of a solar system...

Star Trek seems to take the cake, there.

Um... DEF STAR!!!

Spoiler:
that's no moon

Death Star II, 900 km diameter. Though it's not really a "ship".

Sticking to that vein, a plethora of science-fiction works have used a Dyson sphere, including Star Trek I believe.

If you check the site they came from one of the questions on the FAQ is "Why isn't the Death Star there" "Because we don't have a chart big enough, even scaled down." Oh and technically the Death Star is a battlestation, but it can move and it's equipped with a hyperdrive, so what does it have that a normal ship doesn't, Lucien?

STAR TREK WINS!

All Hail Star Trek!

Heh. I never watched Star Trek or Babylon 5, but then again, they never aired here either.

EDIT: But does it have anything to rival the size of a Death Star?

Then you and the Death Star have something in common, a lack of style.

So after viewing the charts SW wins with the Death Star, interesting.

Apparently bigger than anything in Star Trek, Stargate or Babylon 5, but I'm sure not the biggest in sci-fi.

Again, not sure if this is "sci fi", but Galactus's ship is the size of a STAR SYSTEM, and is speculated to be the greatest source of energy in the Marvel Universe.

Magog world ship.

As someone already mentioned. ST has utilised a type of Dyson's sphere. It's a structure that completely envelopes a star and so captures all it's energy. Civilisations would live on the inside surface of it.

The following Space entities are among the largest yet known:

1. Cetadel (Mass Effect)
2. Alien Mothership (Independence Day)
3. Death Star I (Star Wars)
4. Death Star II (Star Wars)
5. Star Forge (Star Wars)
6. Unicron - The Planet Eater (Transformers)

However, if the Galactus Ship is as huge as Hewhoknowsall asserts than it is perhaps the largest space entity yet introduced in the Sci-Fi genre.

What characterizes a ship? All the big ones we're naming are more like stations.
