While its parent nation was ferociously developing the logistics to mass produce the new jet engine technology, their allies to the south acquired several SR-8s as part of an arms exchange program. They wasted no time in outfitting it with their own cannons and high octane fuel which boosted the engine's efficiency.

While these improvements were shared, the Mad Duck's nation of origin had already designed its facilities for the MK I originals. (messing around with a friend, DukeOfDetroit)
