Known as "Dinah" to the Allies, this elegant two-engine plane was the best high-altitude long-range reconnaissance plane that the Japanese put into the field in World War II. Its high speed allowed it to frequently avoid Allied interceptors for most of the war, making it a well-respected thorn in the Allies' side. The Ki-46 was kept in production continually from July, 1941 until the end of the war. A total of 1,742 aircraft were built. Mitsubishi began the Ki-46 project in December, 1937 at the request of the Japanese army authorities. The first prototype began flight tests in November, 1939. The first version was known as the Ki-46-I, which was superseded by the Ki-46-II (the main difference being more powerful engines). The next version, which came out in December 1942, was the Ki-46-III, and had markedly improved speed and performance, as well as a noticeable external design change that extended the pilot's canopy from the stepped version shown in the drawing above all the way to the tip of the nose (see the color drawings page for examples). Additional versions were designed, including the Ki-46-III Kai which was armed for the role of a home defense interceptor. Results for this version were disappointing, however, and despite further enhancements in the Ki-46-IV versions (one as a Command Reconnaissance plane, and one as an interceptor) both versions were eventually deleted from the production priority lists. All in all, the Dinah earned its place in aviation history as one of the more graceful looking and one of the fastest planes of its type during the war.
