「我ニ追イツク敵機無シ」有名な無電を発した俊足の艦上偵察機「彩雲」。敵戦闘機の追随を許さない高速性能を誇る、高性能な艦上偵察機です。悪化した戦況の中、敵情偵察に海上へと 飛び立ちました。その「彩雲」を航空機格納庫を持つ潜水艦空母に格納して輸送できるように分解しました。 "No Grumman could catch us" was the famous telegraph sent from this reconnaissance aircraft, "Saiun". This reconnaissance aircraft boasts high-speed performance no enemy fighter can overtake. As the war deteriorated, this aircraft monitored enemy movements at sea. This "Saiun" has been dismantled so it could be transported by being stored in the hangar of an Aircraft Carrying Submarine.
