What good would 360 degrees of weapon coverage be? With people above and below you you'd still need to turn to line things up and if you're firing so many guns you're going to stick out like a sore thumb allowing anyone with a stealthier ship and just one big cannon to punch you full of holes while you beat up some unmanned drones or whatnot.

[Heron TSG]

You don't need to turn to line things up if your gun turrets (with at least a moderate swivel capability) cover every access point to your ship.

Perhaps, but it's nice to be able to conentrate firepower into a broadside by making the turret coverage somewhat lopsided and compensating for it with maneuevering thrusters.

Anyway, spaceship are illogical: swarm of robot or just plain old missiles are much more efficient.

Yeah but there's no reason to say but there. I was already talking about how you want lopsided turret coverage and to turn, you know, in response to the claim that the design was good because they covered 360 degrees.

What I was actually interested in though was not so much guns but what the internal structure is like. On a space ship it is easy to image guns scaling to practically any size but so this 500 meter claim doesn't mean anything in regards to that but living quarters, the bridge, and so forth- well those have to be scaled to humans and thus the size is really about how those fit into the ship's design.
How big are the engines and how much fuel storage space is there? How long could this fly around based on that, how much more fuel is used during combat maneuvering...

Kinda, that's why military vessels are so often flat or diamond shaped (remember that Star Wars Imperial ship? Too much random junk sticking out, but a well chosen shape), and have decreasing height as you go from the back end to the front end; so they get one direction where they can use all their guns, and can use half their guns in all side directions. This does, however, often put such ships at a disadvantage from behind, but the fact that they always want such monstrous, quaking engines makes this already the case. (Heh, I remember exploiting exactly that in the ICP.)

Predit: I was "ninja'd" so easily.

Are you sure you didn't read a certain design document and are making this for something specific? :⌡

I recall just getting bored and extruding faces from a box, no design document. I'm just bored.
Also, I had in mind my previous ship which I didn't post:

The engines are fusion plasma based and are a derivative of the VASIMR engines. I guess the ship could fly around for as long as it wants as long as there's a viable source of fuel around, though it could last six months cruising around and a week or two of combat maneuvering.

Also, the ship's geared towards broadsides with an opening punch from its spine mounted main gun.
ED:
Since when did a modeling thread become a science thread?

[Rysith]

Since when did a modeling thread become a science thread?

Since you admitted that you were trying to make a spaceship that was trying to be realistic, rather than a more space-opera-y battleship-in-space, and then moreso when you started mentioning things like VASIMR.

As a side note, that's an enormous amount of fuel. Remember that most 'realistic' spaceflight is spent drifting, especially since you've got the spinal gun and thus you'll want to be able to approach a target to within firing range[1], engage it, and only then rotate to decelerate. I remember Atomic Rockets (http://www.projectrho.com/rocket/) being a decent resource for working out as many of the realistic space flight issues as you care to (and I also fully support handwaving at least some).

[1] Firing range is going to be dependent on whether it's a beam weapon or a projectile weapon, but is basically defined as the point when the target cannot shift itself enough to avoid a hit in the time that it takes your sensors to find them and then your projectile to reach them. Lasers are a bit more complicated because, although they are faster, they also have focus issues, but the principle is the same as long as you aren't shooting at large and/or low-acceleration things.

[Sheb]

Also, I don't know how you intend your starship to be used, but some sort of bombing bay would be nice also.

[rarborman]

I just figured out why your ship looked familar to me...

It looks very similar to this ship, although you can say that about many of the long blockish ships out there...

Looks good though dont get me wrong.

[Bien]

Spoiler (click to show/hide)

Well, if you do a barrel roll. It looks a lot like that ship from beneath. Note that the thing with windows isn't the bridge, it's the recreation deck.
Also, the weapon's an ion beam cannon (like the one from Homeworld).

[rarborman]

Ok, now I want to see a, at least basic, diagram of the internals, cut top down to view at least one deck with outline of total ship...standard would be blueprints for ship building, but without all that  technical stuff like realistic plumbing and wiring. 

[Shoku]

Oh so it's a 99% firepower straight forward thing with just some short range stuff in all directions to deal with little fighter type things that might swarm it?

Not at all. I'm still making the primary turrets and their mounts. But those little holes are VLS arrays.
ED:
Question: Is this large enough for a heavy gun battery? The cylinder is 1 meter in height by 1 meter in radius.

[Heron TSG]

The barrels seem a tad undersized for a weapon that shape, but I suppose you could justify that by wanting to reduce the 'kick' as much as possible. Is there a reason that the turret is shaped like that in particular, though? One meter tall doesn't allow anyone to be inside, so it's probably unmanned. If that's the case, why add the details and not just make the whole thing one big armored block?

Just trying to help with 'realism'.
