Introduction

高性能多用途水上偵察機「瑞雲」の改良型「瑞雲12型」。
同機によって編成された「伊勢」型航空戦艦などでの艦隊運用を担う六三四航空隊所属の「瑞雲12型」飛行隊です。

The "Zuiun Model 12" is an improved, high-performance version of the "Zuiun" reconnaissance seaplane.
This is the "Zuiun Model 12", belonging to the 634th Air Group, responsible for fleet operations of those seaplanes on the "Ise-class" aviation battleships.

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).

This plane has strong Anti-Air Resistance.

0.7 Fleet AA Modifier
