There is confusion. In the U.S When something is given a numerical addition, it indicates a completely new airframe (or "weapons system" as the military likes to call them). The F-35 (Lightning II) is in no way shape or form an advanced version of the P-38 (Lightning)!!You know, the kilrathi did that too with the dralthi.
Yep - the image of Kilrathi engineers frantically revising the Dralthi and trying to make it less of a deathtrap over the course of WC1, 2, Armada, and Privateer always makes me smile.You know, the kilrathi did that too with the dralthi.
