History:

In September 1941 ordered the command of the imperial army air force (大日本帝国陸軍航空本部 Dai-Nippon Teikoku Rikugun Kōkū Hombu) for the company 川崎航空工機業株式会社 - Kawasaki Kōkūki Kōgyō Kabushiki Kaisha (hereinafter Kawasaki) the development and construction of six prototypes, specialized in dive bombing. Army air force for the first time, have shown interest in this category of aircraft, naval air force dive bombers in its arsenal, but it tried to their existence a secret, at least to elude the title of "dive bomber", more Aichi D1A.

Command of the army air forces also closely followed the war events in Europe from the very beginning, and so the relevant intelligence notice also the initial great successes of the German bombers Junkers Ju 87. Some of were the Japanese certainly influenced even the German propaganda. For us it is important, however, that the command of the army air force was required after the company Kawasaki dive bomber. The technical department of the air force, however, on the basis of their analyses requested a twin-engine aircraft, carrying a bomb load in fuselage bomb bay. It was a relatively small weight of bombs (even on japanese standards), the new aircraft had carried away only 300-500 kg of bombs, the weight of the bombing of the cargo depended on the planned range. The effect of the raid was to be raised postřelováním targets fixed machine guns.

Design work on the project, indicated in the system Kitai as the Ki-66, took the experienced designer engineer Takeo Doi. As a basis for the new machine chose a twin-engine light bomber Kawasaki Ki 48. The whole design of the light bomber had to be firm, to withstand high loads when picking a dive, the crew would be sufficient two-piece, in front of it was no longer a gunner/bombardier, the front part has already been glazed, neprosklenou bow can be better aerodynamically sculpt and soften the blow. In the bow is so freed up enough space for the installation of two fixed velkorážových machine guns the Ho-103, for the defense of the aircraft towards the rear, were carried by two machine guns the Type 89 model 1, one was installed in the dorsal střelišti and the second shooter in a considerably limited range to shoot výstřelnou slit in the back under the plane (bomber Ki-48 here bore the tipping range in prosazeném hull). Outside the engines were, on the front of the beam wing, tilting aerodynamic braking bars. Their flip against the direction of flight, eased the speed of the aircraft. When the exact altitude of the raid drop rate to allow a better controllability of the airplane, and also the collection of this flight was for crew more bearable.

The prototypes were produced from October 1942 to April 1943, and all six involved in the trials, the results of the tests were quite positive and the military test, the commission found no major shortcomings and so it would seem that nothing prevents the introduction of dive bombers in the arsenal. Unfortunately, the new bombers, the Ki-66 in the series production ends. To blame it was the older sibling in its latest version Ki-48-IIb, which in the meantime came into production. This new version was able to meet the requirements of the army air force because it was able to carry out, inter alia, also dive air raid and the performances were similar.

A promising type of Ki-66, so in the end he stayed only for the mentioned six built prototypes and Rikugun Kōkū Hombu in October 1943, the entire project stopped. Even before the stoppage of work was one of the aircraft tested with the more powerful engines Nakajima Ha-315-I capacity of 1 360 horsepower, marked was as the Kawasaki Ki-66b.

There were several other projects with more powerful engines - Ki-66c had to get the engines Nakajima Ha-39 with a capacity of 2 100 hp and Ki-66d was to be powered by engines Nakajima Ha-45-11 Homar about the performance of the 1 825 horses. The drawing stage beat even a heavy fighter Kawasaki Ki-66-II.
