''This design began as a land-based fighter under the New High-Altitude Fighter development plan, it then continued development as the No.18 Prototype Armored Fighter under the Navy's state-of-the-art next-generation mainstay fighter plan.<br>Due to the deteriorating situation, the plans were abandoned in favor of the relatively more realistic "[[Shiden|Shiden Kai]]" development plan and "[[Reppuu]]" program, with plane being a what-if trial mass-production model of that discontinued plan.
