The X-4 "Raitoningu" was forced off the line before it was 100% complete. Tho it was supposed to have a 20mm automatic Jagger cannon the first one had a 30mm.
It was heavly based on the X-3 yandere high speed and highly dependant on it missles. The gun was added so it could more aporpitly attack ground targets that are on thier own.
It was made after a A-10 worthog shot down a x-3. During its maiden flight the first one went head to head with the ME-898 "Vulfrost". Made to do the same job but in different ways. The Vulfrost was highly dependant on its guns. The high speed fighting ended with a head to head crash that ended with them crashing in Israel occupied territory. They went 5603 miles from the crash point. Crashing just outside Gaza when they were fighting near new York City.
The pilot Sigurd Dämon leader of Russia was dead by the time he hit the ground from the stabilization bar impaling him.
