This is my favorite ship in Star Wars. It really shows the evolution over time. First the Acclamator in Episode II, It has a long tail (hyperdrive), it's engines stick out a lot and it has a small bridge tower. Then by Episode III, we have the Venator. It's tail is cropped shorter, it's engines are bigger but are more recessed and the tower expands and doubles it's protrusion. Til finally the Imperial class, It's the largest; it's engines are almost entirely sunk in. It's tower expands and is completely recessed to the back and it's tail is gone.
