what is it?
The Aichi H9A was a flying boat trainer designed and produced by the Japanese aircraft manufacturer Aichi. It was operated by the Imperial Japanese Navy Air Service (IJAAS) during World War II for crew training, receiving the designation "Type 2 Training Flying Boat" (二式練習飛行艇, Ni-shiki renshū hikō-tei). Being an relatively uncommon type, it was not encountered by Allied forces until Spring 1945 and thus was never assigned an Allied reporting name.
How to recognise it: 2 piston engines with propellers · 24 m wingspan
