Aichi H9A

The Aichi H9A (二式練習飛行艇, Navy Type 2 Training Flying Boat) was an Imperial Japanese Navy Air Service flying boat used during the first years of World War II for crew training.

[1][2] The H9A was a twin-engined, parasol-wing flying boat, designated by Aichi as their AM-21 design,[3] and it was designed in response to an Imperial Japanese Navy requirement for an advanced seaplane trainer for future crew members of the four-engined Kawanishi H8K "Emily" flying boat.

Design work started in January 1940, and the first of three prototypes was flown in September 1940.

[1] From May – June 1942, the Aichi H9A was employed in a variety of second-line roles, including anti-submarine missions along the Japanese coasts, transport, paratroop training, and liaison.
