Introduction
急降下も可能な多用途水上偵察機「瑞雲」。
伊勢型航空戦艦等での艦隊運用を前提に編成・錬成した、六三四航空部隊所属の瑞雲飛行隊です。
A multirole float recce plane, Zuiun was designed to carry out dive-bombing as well.
This Zuiun belongs to 634th Air Group, grouped and trained for practical application on aircraft-carrying battleships such as Ise and Hyuuga.
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 Imp.
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 Anti-Air Resistance.
- 0.6 Ship AA Modifier
Notes
Not to be confused with other aircraft of this family (see here).

Trivia
The 634th Air Group was a sort of carrier aircraft division, which belonged to aircraft-carrying battleships Ise and Hyuga (they were to carry 14 and 8 Zuiun's respectively) in the latter half of the war in the Pacific. The air group was initially trained to be catapulted off battleships, but later transferred to ground bases in the Philippines, and Taiwan as well as Japan mainland after October 1944, thus never seeing an action they initially intended. 634th Air Group's mission was dive-bombing and strafing toward American vessels during nighttime, and they kept themselves clear of so-called Kamikaze suicidal attack until the very end of the war (hence the higher stats, reflecting the Air Group's high skill level).
