 | | Kawanishi replied with a new design, the "Type S", that had been evolved from the two earlier submissions. |
 | | The Type S was accepted, and the first of four prototypes of the "H6K1", as the IJN referred to it, performed its initial flight on 14 July 1936, with Katsuji Kondo at the controls. |
 | | The 18th H8K flying boat was built with uprated MK4Q Kasei 22 engines, each with 1,380 kW (1,850 HP), plus a modified tailfin and increased fuel capacity, and was given the new designation "H8K2 Type 2 Model 12". |
