Mitsubishi's Ki-46 series was code-named "Dinah" by the Allies.
The prototype of this sleek, multi-purpose Japanese aircraft flew in November 1939. It was originally specified as a 600kph replacement for the Ki-15, and although the prototype did not quite meet this performance requirement it was still faster than any contemporary Japanese aircraft.
The original production version was the Ki-46-I Army Type 100 Command Reconnaissance Aircraft. This first version was quickly replaced by the Ki-46-II with the more powerful Ha-102 engine. These engines were equipped with a two-stage supercharger. The additional power finally allowed this version to exceed 600kph.
The streamlined perspex nose can identifies the Reconnaissance versions. Over 1,000 of the Ki-46-II were produced.
The ultimate Dinah, the Ki-46-III, was powered by the Ha-112-II.
The fighter version was a development of the Ki-46-III Reconnaisance Aircraft. Investigations commenced in June 1943 and the "step nosed" fighter entered service by November 1944. Sluggish climbing characteristics meant that this speedster was not as effective in the fighter role as hoped, but production continued. Over 600 Ki-46-IIIs were eventually produced.
Tamiya produce both the Reconnaissance version of the Dinah (Ki-46-II) and the fighter (Ki-46-III KAI) in 1/48 scale. The kits do justice to the graceful lines of these aircraft, while the detail and ease of construction are exactly what one would expect from Tamiya in the 1990s - close to perfect!
Chris built his Dinah fighter almost out of the box. It is painted with Tamiya acrylics. Another superb job.

The Cosford Aviation Museum in England has restored a Ki-46-II. Museum staff have carefully reproduced the structure and appearance of the aircraft, using paint samples to match the new colours wherever possible. The result is stunning.
