The Yokosuka E5Y Type 90-3 was a single-engine Japanese seaplane used for reconnaissance.


The Yokosuka Type 80 Model A seaplane was the first in a series of seaplanes developed at the Yokosuka Naval Arsenal in Kanagawa Prefecture. The E5Y was a second-generation seaplane with a 540 hp engine based on an updated Yokosuka E1Y. The biplane featured two externally mounted floats. The Japanese Navy designated it as the Yokosuka Type 14-2 Kai-1 Reconnaissance Seaplane.[1] [2] By 1932, the Aichi AB-6 was under development to replace the seaplane.
