During the failed 2001 continuation project to revive Battlestar Galactica conceptual artwork was once again drawn up by Guy Dyas of both the exterior and interior of a new Advanced Raider.
On the outside the basic shape and size remained the same but the new design had slightly extended wings and a more meanacing front.
The interior, however, was much more detailed than the original which was very sparce of instruments. The new interior design gives a more more realisic view of a space fighter.
The new shooting script also called for a dedicated "Pilot Cylon" which looked slightly different to the regular ones. It is unknown if all three seats were occupied by Pilot Cylons or just the main front seat would.
