Introduction

12cm30連装噴進砲は、艦載用対空ロケットランチャーです。
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 12 cm 30-tube launcher is an anti-aircraft rocket launcher for ships.
The threatening barrage that fires 30 consecutive rocket-type shrapnel shells (RoSa shells) protects allies from fragile enemy carrier-based aircraft.
By all means, pack these onto the refurbished Ise and Hyuuga and break through the onslaught of enemy aircraft carriers!
