I assume Scourge is intended to be a bigger jet that just looks a lot like the X-48. It is a bit amusing given how small the IRL plane is though. Still a good looking mold.
Actually, I'll be real, different "types" of Sweep would be cool as fuck. Maybe a ground Sweep that turns into a tank that looks like a blend of the classic soapdish spaceship and the AAT from SW.
