Design and development

The Aichi E16A originated from a 1939 specification for a replacement for the Aichi E13A, which at that time had yet to be accepted by the Imperial Japanese Navy Air Service (IJNAS).[2] Disagreements about the requirements in the 14-Shi specification prevented most manufacturers from submitting designs, but in 1941 a new 16-Shi specification was drafted by the IJNAS around the Aichi AM-22 design which had already been made by Aichi engineers Kishiro Matsuo and Yasuhiro Ozawa.[2] The first AM-22, which first got the experimental designation Navy Experimental 16-Shi Reconnaissance Seaplane and later the short designation E16A1, was completed by May 1942 and was a conventional, low-wing monoplane equipped with two floats and had the unusual (for a seaplane) feature of being equipped with dive brakes, located in the front legs of the float struts, to allow it to operate in a secondary role as a dive bomber.

Die Aichi E16A Zuiun (jap. 瑞雲, dt. „günstige Wolke“; alliierter Codename Paul) war ein Aufklärer und Sturzkampfflugzeug der japanischen Marineluftwaffe im Zweiten Weltkrieg. Ungewöhnlich für ein Wasserflugzeug war die Rolle als Sturzkampfflugzeug und die in diesem Zusammenhang in den vorderen Schwimmerstreben eingebauten Sturzflugbremsen, die sich seitlich öffnen ließen. Sie löste die Aichi E13A ab.
