Mechanics
Seaplanes are the main aircraft type used by non-carrier ships (mainly battleships, cruisers, and auxiliaries).
- They are notably required to trigger Artillery Spotting.
Bomber Seaplane Bombers additionally act like Dive Bombers, taking part in the same air phases and sharing the same damage formulas. Additionally, they:
- Play some minor Anti-Installation role.
- Bring an accuracy bonus against PT boats.
Zuiuns are additionaly required for the Ise-class Kai Ni
to perform special Zuiun cut-in attack (see Artillery Spotting for more details).
Notes
Not to be confused with other aircraft of this family (see here).
