ww2dbaseThe N1K Kyofu ("Mighty Wind") fighters were offensive weapons designed to sit atop floats, providing capability to cover ground advances without needing airfields. The design work began in Sep 1940 as the Japanese Navy issued the request, with the intention to use such aircraft for the southward expansion. On 6 May 1942, the prototype flew atop of one primary float and two auxiliary ones. The response from the test pilot was positive, noting it was easy to fly and rather maneuverable. Service trials began in Aug 1942, and they were delivered to the Navy in Jul 1943 in extremely limited numbers. They were assigned the Allied codename "Rex".

ww2dbaseJapan had reached their greatest reach of offensives by 1943, however, and had fell into a defensive stance, and N1K fighters never had a chance to fill the offensive roles they were designed for. Instead, they were assigned as interceptors based out of Balikpapan, Borneo. Though capable as floatplane fighters, floatplanes were not meant to fly against fighters. Consequently, production on the N1K ceased in Mar 1944 after a limited production number of only 89.

ww2dbaseThe N1k was too solid a design to abandon, however. In early 1944, the N1K-J Shiden ("Violet Lightning") variants entered production. The floats were removed from the aircraft, replaced with long landing gears. Combat flaps that were automatically adjusted during different flight conditions were also installed, which were an innovative technological revolution at the time, allowing the pilots to deal with one less thing during stressful combat situations. Reborn as true fighters, aircraft of this new generation of the N1K design soon proved to be highly effective against American fighters. They deployed in the Philippines, Formosa, and Okinawa in an attempt to stop the American juggernaut, though reliability issues due to a rushed production time table haunted pilots and mechanics alike. Before the end of the Pacific War, 1007 N1K1-J and a handful of the upgraded N1K2-J fighters were produced.

The N1KI-J Shiden entered service with the J.N.A.F. early in 1944, and despite troubles with its Homare engine and shortcomings resulting from the inadequate development period, it soon proved itself a redoubtable warplane, and its pilots came to look upon the formidable Grumman Hellcat as a relatively easy kill.

Famous WW2 Quote
"All that silly talk about the advance of science and such leaves me cold. Give me peace and a retarded science."
