One of the best-looking Japanese aircraft of World War II, the Mitsubishi Ki-46 was designed to meet an Imperial Japanese Army requirement of 1937 for a higher performance reconnaissance aircraft to supersede the Ki-15. A cantilever low-wing monoplane with retractable tailwheel landing gear, powered by two 671kW Mitsubishi Ha-21-l radial engines, the two-seat Ki-46 prototype was flown for the first time in late November 1939. Early testing showed that maximum speed of the Ki-46 was some 10% below specification, but as its speed and overall performance was better than in-service army and navy aircraft the type was ordered into production as the Army Type 100 Command Reconnaissance Plane Model 1 (Ki-46-l), later allocated the Allied codename 'Dinah'. Early operational problems with the Ki-46-l resulted in production of the improved Ki-46-ll with 805kW Mitsubishi Ha-102 engines, this powerplant giving a maximum speed slightly in excess of the original specification. The Ki-46-ll was the major production version, with more than 1,000 built, a number of which were converted later into three-seat radio/navigation trainers under the designation Ki-46-ll KAI. Subsequent variants included the faster and improved Ki-46-III of which 609 were built, a small number being converted later as Ki-46-lll KAI fighter interceptors and Ki-46lllb ground-attack aircraft. Ki-46-IV prototypes, with 1119kW Mitsubishi Ha-112-ll Ru turbocharged engines to give improved high altitude performance, were under test when the war ended.
In service from the beginning to the end of the Pacific war, the Ki-46 proved to be an important aircraft for the Japanese army, but the growing capability and number of Allied fighters resulted in unacceptably high losses of Ki-46-IIs. However, the improved performance of the Ki-46-lll meant that this
version was virtually free from interception until the final stage of the war. Production of all versions totalled 1,742, all built by Mitsubishi.

This plane was called "ShinShiTei" it did not have a fancy nickname like the other fighters. It meant "new commanding surveillance. Though it is called surveillance plane towards the end of the war it was also used for "kamikaze". Sad to see such a beautiful plane be handled in such way.

That is one seriously sleek airplane...it's almost mesmerizing

The Mitsubishi J2M3 was called the Raiden, translated 'Thunderbolt', the Kawanishi N1K1-J was called the Shiden, translated 'Violet Lightning'and the Aichi B7A was called the Ryusei, translated 'Shooting Star'. But what was the Mitsubishi Ki-46 called? I'm not referring to its Allied identification codename,'Dinah', either.

The last surviving 'dinah' is displayed at raf cosford, with the only complete ME410

I read someplace that the Luftwaffe was interested in this plane. Imagine if something had come of that!

Like the Italian SVA-5 of WW1, Dinah could elude interception in the recon role but failed all attempts to achieve a combat role, such as done by by the Mosquito. As such, it could only provide the news that Japan was losing the war. Sure was a looker, tho.
It is a beautiful aircraft...if there's one thing Japan knew, it was how to design a striking airframe (at least as much so as the Germans).
If tests of the turbo-equipped engine had been completed, the allies could have had problems...

This warbirds were extensively used over Malaya, the current Malaysia. It holds a significant degree in defining the todays Malaysia. It would be invaluable if any parts of the original 2 seaters Dinah can be obtained and displayed in the country. Any party with such information of such parts of Dinah is highly sought after by us, really. Regards
Do you have any comments about this aircraft ?
