Japans need for single seat , float equipped interceptor seaplanes prompted the Japanese Navy to initiate a development program in 1940.This highly imaginative and attractive design was started in that year.This aircraft retained the same armament as the A6M2 and had a design feature to counter the torque-induced swing swing on takeoff.The wing mounted floats, though not intended as such ,were fixed due to problems.

Name this aircraft. Answer by PM only. Do not answer " Was It ". Answer will be posted Tue 11 / 07
