Aha. Yes, the ship is 130km. But it's using systems far more advanced than those found in star wars. It is highly maneuverable, much more maneuverable than most of the Gahennas ships of a smaller classification. But I understand what you mean.
The interior of the ship is made out of energy, while the exterior is made out of a stone-like crystal from the inner circles of Hell. Although it has a tremendous amount of mass, its energy output is absurd. It can achieve higher speeds faster than virtually any kind of jump system fielded by mortal races. Its turning speed isn't so quick, but it is still capable of fairly ridiculous maneuverability. At least, in transit mode, anyway. Once it enters full combat state, it powers up a quantum energy barrier and the engines dis-engage to become Destroyers. Then it loses the majority of its speed and maneuverability, and acts as a Command and Control.
The side engines are the key to the ship's speed and maneuverability. They are Destroyers, coupled to the ship through an energy bond. The Destroyers themselves are specially-designed for this link, and their energy output is largely directed towards thrust by emitting elemental energy. Smaller ships, like the Gahennas Battlecruiser and the Gahennas Eradicator, don't possess special drives like this, and aren't nearly as maneuverable. (Well, the Eradicator is only 20km, so it is comparatively maneuverable, but not as fast. The Battlecruiser is much slower and more built to range down its opponents)
But I agree when the ship launches it should be a bit slower and more dramatic. I'm going to touch up the scene after I finish the first scene, the explosion scene I showed before. I'm making headway in my understanding of Afterburn.
And here's another render.
As you can see, I found someone to skin my Dreadnaught.
