the AUI-21X was a big succes to the AUI corps, but since it have high radar detection, the AUI corps upgrade and rebuild it, as a result the 42x was born. 42X meets several errors, like the Inverse-rotation, low speed, and lack of electronic warfare systems. the 42X upgraded into the 84X, but the inverse-rotation was still there, so, we take our old 21X design, and rebuild it with new materials, and adding an electronic warfare system, the 101X was born, as a STOL stealth interceptor, it wasn't that good because of it's stability in pitch. after long seconds of research, we got a new idea, a canard jet fighter capable of mach 5, but it was to bigh that the wings explode, so we make it smaller and slower, to mach 3, and the result: THE 121X, A TALENTED FIGHTER WITH LIQUID NITROGEN POWERED JET ENGINE, THE BEST FROM THE AUI-[NUMBER] SERIES
