Design
The K6K was a two-seat, twin-float biplane with a welded steel-tube fuselage, covered in fabric, light alloy, a steel wing covered in fabric, and monocoque floats built from light alloy. It was conceived in response to an Imperial Japanese Navy requirement for an intermediate-level training seaplane. The first flight of the K6K occurred on 30 April 1938, but flight tests revealed poor alighting characteristics, so the K6K was not ordered into production.[1]
