Design and development
In 1937, the Imperial Japanese Navy requested the Kawanishi Aircraft Company and Aichi Kokuki to design a replacement for the Navy's E7K seaplanes.[2] Kawanishi's design, given the short designation E13K and long designation Kawanishi Navy 12-Shi Three-seat Reconnaissance Seaplane, was an all-metal, single-float seaplane armed with one Type 92 machine gun and either one bomb under the fuselage or four bombs under the wings.[3]
The first of two E13K prototypes flew on 28 September 1938. In October 1938, the aircraft was transferred to the fleet base for testing, and, even though the E13K outperformed the Aichi E13A except in maximum speed, it was difficult to operate, so the Navy chose the E13A to be the replacement for the E7K.[3][4] The first prototype suffered an accident due to excessive vibration, and the second vanished during a test flight and was not recovered.[1]
