同機主翼を中翼から低翼配置に改め、さらに自動空戦フラップの改良や防御力向上など、各種改良を施しました。
大馬力エンジンと空戦フラップ、そして火力と防御力。
零戦を大きく凌ぐ優れた空戦能力を持つ、海軍本土防空最後の切り札となる名機「紫電改」、その初期型の誕生です。
The "Shiden" is a short-range fighter developed from the Kyoufuu seaplane fighter.

This is an early model of the "Shiden Kai" with abilities that surpassed the Type Zero fighter, it formed the cornerstone of the IJN's homeland air defenses.
