The Aichi E16A Zuiun (瑞雲 "Auspicious Cloud", Allied reporting name Paul) was a two-seat reconnaissance seaplane operated by the Imperial Japanese Navy during World War II.

[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.

It 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.
