A carrier-based torpedo bomber developed as the successor to the Type 97, the "Tenzan".
Its engine has been replaced and armament strengthened. This is an improved late-model "Tenzan" with improved specs.
Use them on carriers like Shoukaku, Zuikaku, and Taihou for improved results.


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).
