Introduction

艦載用対空ロケットランチャー「12cm30連装噴進砲」をさらに戦訓によって改良した強化改修型です。
後方ブラスト対策や再装填、さらに射撃装置にも改良を加え、噴進式対空焼霰弾連続発射の弾幕により、肉薄する敵機から味方艦を護る能力はさらに向上しました。
「伊勢改」及び「日向改」では、さらに高い防空効果を発揮します。

An improved variant of the ship-based anti-air rocket launcher, the "12cm 30-tube Rocket Launcher", further refined by lessons learned in combat.
With improvements to backblast countermeasures, reloading, and even fire control, the ability of the launcher's continuous rocket barrage of incendiary anti-air shrapnel to shield friendly ships from thinly armored enemy aircraft has further improved.
"Ise Kai" and "Hyuuga Kai" high anti-air effectiveness stands out further with this.

Mechanics

• Are notably required in most AACI.
• Trigger a tracer-fire effect during air combat.
• Bring an accuracy bonus against PT boats.
• Is required for AACI n° 25, 27, 28.
• Enables Anti-Air Rocket Barrage on BBV, CAV, CV(L/B), and AV.
