Kawanishi E13K

The Kawanishi E13K, company designation AM-19, was an experimental Japanese three-seat reconnaissance floatplane of the 1930s, of which two prototypes were produced. In 1937 the Imperial Japanese Navy asked Kawanishi and Aichi to design a replacement for the Navy E7K seaplanes, and Kawanishi answered with an all-metal, single-float seaplane armed with one Type 92 machine gun and a bomb load carried under the fuselage or wings, powered by a Mitsubishi Kinsei radial piston engine. The first prototype flew on 28 September 1938. Although it outperformed the Aichi E13A except in maximum speed, it was difficult to operate, so the Navy chose the Aichi design; one prototype was lost to vibration and the other vanished on a test flight.
