Developed as the successor of the obsolete "Type 97 Torpedo Bomber", the new carrier-based attack aircraft "Tenzan".
When deployed in a mobile squadron, it is mainly responsible for fast-strike missions.
Together with the "Suisei" dive bomber, please operate it as part of your aircraft carrier mobile squadron.


Torpedo BombersTorpedo BomberNight Torpedo Bomber/Night Bomber are one of the main types of plane used by CV(B/L). Their main role is to do damage during the Airstrike, with their "Torpedo" Torpedo Attack stat being the most important factor in this regard. Torpedo Bombers are additionally needed for dealing damage during day Shelling, especially for Aircraft Carrier Cut-Ins (CVCI).


Not to be confused with other aircraft of this family (see here).
