I was thinking along the lines of a future Confed destroyer 
Although those massive turrets need to be chopped down quite a bit.
And if you decide to remove the engines, I want a copy beforehand... their perfectly designed for bussard intakes.
I'd agree with that

. And I'd like a copy of it at that stage, too

.
As to what you've done with it - I sort of miss the big side-mounted turrets, and also I'd rather have used WC2-style textures (because of the "bridge" it mostly reminds me of the Concordia...). But the extra detail does help it...
Oh, and what's that background of yours? Looks really good

.
And as for what I'd have done with it (not to say that I'd have been anywhere near as fast as Scooby_Doo), I'd say I could use it for sort of a strike-cruiser in FS - quick, heavy armed (some cap-beams on those turrets; or maybe sort of heavy plasma gun or even Helios launchers), but little anti-fighter defense and somewhat restricted arc of fire (as FlareBaffled said, just that I'd turn it into a feature instead of complaining about it

).
And it'd be best to use Deimos-like textures, in that case.
(Yup, I said it reminds me of Wing Commander - but then, I prefer the FS timeline and so tried to spot a place for it there

)
