Yokosuka E5Y

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

Development
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. By 1932, the Aichi AB-6 was under development to replace the seaplane.

Operational history
On 25 May 1932 the IJN Seaplane Tender-Oiler NOTORO Re-equipped with Type 90 No. 3 Kawanishi E5K/E5Y three-seat reconnaissance floatplanes. The Japanese seaplane tender Kamoi carried a complement of 12 E5Y aircraft.
