Introduction

時代はオートジャイロから、ヘリコプターへ。
あの時代に原型機が既に初飛行を実現、哨戒や連絡などを中心に実用化が始まっていた回転翼機、初期のヘリコプターです。
戦後、海上自衛隊にも導入された同機のif対潜哨戒型の艦載ヘリです。

The autogyro has now evolved into the helicopter.
his is an early helicopter, whose prototype had already flown, and had begun to be used for patrol and communication purposes.
This is a what-if version that might have been introduced to the Maritime Self-Defense Force after the war.

Notes

Rotorcraft are ASW Aircraft, being used to trigger some OASW and Land-based ASW attacks.

As they do not have any Dive Bombing stat, they do not participate to Phases 2 & 3 of Aerial Combat and are immune to shootdown. They:

• Will launch during aerial battle if other planes are launched, but cannot start an aerial battle on their own.
• Allow BBV, CAV, AV, and LHA to perform ASW attacks.
• CVL and Kaga Kai Ni Go equipped with them will still require a Dive Bomber or a Torpedo Bomber to attack submarines, as they are unable to attack anything without a bomber.
• AS, AR, and some CVB can equip them, but the former cannot attack SS, and the latter has a carrying capacity of 0 so they do not function.
• AO can equip them, but their attack animation will still be a depth charge animation.

Their LBAS Combat Radius cannot be extended.
