Introduction

制空権を失った空でも強行偵察が可能な高性能水偵を目指して開発された、十四試高速水上偵察機「紫雲」です。
火星エンジンと二重反転プロペラの採用、投下可能フロート機構などで高速高性能な次世代艦載水偵となるはずでしたが、計画通りの高性能を発揮することは叶いませんでした。
就役直後の軽巡「大淀」などで、増加試作機が運用されています。

The "Shiun" was conceived as a high-performance seaplane intended to scout the enemy where air superiority is lost or unachievable.
A next-generation seaplane powered by the Mitsubishi Kasei engine with a pair of contra-rotating propellers and floats that could be jettisoned for higher speed performance, tests were inconclusive with these features.
Nonetheless, these aircraft saw service aboard the light cruiser, "Ooyodo".

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.

Reconnaissance Aircraft Sp LB Recon are planes that:

Can trigger Contact.

Does not contribute Fighter Power in Aerial Combat, and so cannot be shot down during it (can be shot down during Detection).
When equipped to a Land Base:
- Can extend the minimum Combat Radius in Sortie Mode.
- Add a bonus multiplier to the total Defense Fighter-Power of the base in Air Defense Mode.
- Can contribute Fighter Power (if it has any Proficiency or ), and can be shot down.

Notes

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