Introduction
※ 本土防空の切り札、局地戦闘機「紫電改」の艦載機型、その改良型です。
大馬力エンジンと空戦フラップの採用などによる優れた空戦能力で、実戦化の遅れた次期主力艦上戦闘機「烈風」の穴を埋めるべく開発された
「紫電改」の発動機を中心に改良を施した性能向上型です。
※ This is an improved model of the carrier-based version of the interceptor aircraft "Shiden Kai", our trump card when it comes to our country's air defense.
It is an upgraded version that improved upon the Shiden Kai's engine, featured excellent dogfighting capabilities due to high-horsepower engines and the use of flaps,
and was developed to fill in the spot that was reserved for its successor, the main fighter aircraft "Reppū", as its deployment got delayed.
Mechanics
Fighters
/
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" 
stat being the most important factor in this regard. Fighters are additionally needed for Aircraft Carrier Cut-Ins (CVCI) during the day Shelling.
- They can be used in Land Bases to serve the same role as Interceptors.
Notes
Not to be confused with other aircraft of this family (see here).
