The original of this one was quite bad, though in the game I recall it being a ground hugging nightmare to to eliminate. For open space flight, it really needs an engine on the upper rear, but I couldn't come up with anything that looked good. The bump on top is for mounting a turret.
I suppose it could be a cargo container carrier now- or bring those "legs" up to bring the engines up to the sides. Give it a look from the top and it has a menacing silhouette.
