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|Ise Kai]] and [[Hyuuga|Hyuuga Kai]]'s high anti-air effectiveness stands out further with this. | An improved variant of the ship-based anti-air rocket launcher, the [[12cm 30-tube Rocket Launcher]], further refined by lessons learned in combat.
