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.
Due to the deteriorating situation, the plans were abandoned in favor of the relatively more realistic "Shiden Kai" development plan and "Reppuu" program, with plane being a what-if trial mass-production model of that discontinued plan.


FightersFighterNight Fighter/Night Fighter are one of the main types of plane used by CV(B/L). Their main role is to bring Air Power during the 1st Aerial Stage, with their "Fighter Power" Anti-Air stat being the most important factor in this regard. Fighters are additionally needed for Aircraft Carrier Cut-Ins (CVCI) during the day Shelling.
