四式ロケット式焼霰弾(ロサ弾)を30連発で連続発射する脅威の弾幕は、肉薄する敵艦載機から味方艦を護ります。
ぜひ、改装した伊勢・日向に満載して、敵空母の猛攻を突破してください!

The 12cm 30-tube launcher is an anti-aircraft rocket launcher for ships.

Trivia

  • The name (ロサ弾), "RoSa Shell" is an abbreviated name for "Rocket Shousan Shell". As the name suggests, this is also an incendiary shrapnel shell.
