I'm grateful to Peter Zanella for alerting me to the release of this 1/72 Ki-93 kit from Kora, available in prototype (shown above) as kit KPK72133 and three projected variants. It is injection moulded rather than resin but comes at a 'resin price' of no less than €66. The Ki-93 was bigger than a DH Mosquito though, eight feet wider in wingspan and five and a half feet longer, and only slightly smaller than a Junkers 88. The parts layout shown below looks good but more anon. The three other projected variant kits are KPK72134 Ki-93-1a Heavy Fighter, KPK72135 Ki-93-1b Anti-Shipping Aircraft and KPK72136 Ki-93-1c Ground Attack Aircraft.
The first prototype was damaged in a landing accident and subsequently destroyed in its hangar during a B-29 raid on the Army Air Arsenal at Tachikawa on 19 May 1945 (US Strategic Bombing Survey* report states the raid was on 9 June 1945). A total of 29 B-29s from 313th BW, 6th BG targeted the facility, 18 bombing visually and 11 by radar (according to US Strategic Bombing Survey - but a mission listing states 30 up and 25 bombed**). Damage was light but included two of its four aircraft hangars including that containing the repaired Ki-93. Tachikawa was also the location of the Tachikawa Hikoki K K factory as well as the Army Air Arsenal and the Army's Technical Research Institute, the proximity of all three causing some confusion for writers describing the Ki-93 (and other developments). The Army Air Arsenal had been manufacturing the Ki-51 'Sonia' at the rate of about 22 a month during 1944 and had also produced 49 Ki-43 'Oscars' as well as a single Ki-67 'Peggy', production being curbed by the transfer of personnel to Mitsubishi and plans for dispersal against the threat of bombing raids. It had also been busy producing aircraft engines for the Ki-45 'Nick' and the Ki-84 'Frank'.
The second prototype Ki-93 was moved to Takahagi where it fell into US hands intact during the occupation. That machine was given the designation FE-152, later T2-152, and transported to the USA where it was recorded at Middletown Air Depot on 10 March 1946. No photographs seem to exist or have surfaced and although recorded as being restored during September 1946 for inclusion at the proposed Air Museum at Park Ridge sadly it disappeared from the record after 1949.
The original colour scheme is uncertain. Kora opt for orange on the box art whilst other depictions include a grey green or light green finish. Monochrome photographs suggest an overall mid-toned colour scheme with the wing leading edge IFF strips showing lighter against it, and a distinctive, darker colour swept around the cockpit and over the nose. The tone of the main airframe is similar to that seen in some photographs of the Ki-46 interceptor variant so could possibly be a khaki colour. If that darker segment was intended as anti-glare it did not extend to the engine cowlings. Tonally the dark area on the nose appears similar to the spinners and prop blades. There is no hint of a lighter under surface colour but recently two contemporaneous reports were encountered describing Army aircraft in an overall blue grey finish but with a lighter tone on the under surfaces. Whether that was deliberate or simply resulted from a darkening of the more exposed upper surfaces contrary to conventional wisdom about paint fading is unknown. If the design had proceeded into service it would probably have been finished in the late war # 7 olive brown colour or the blackish-brown # 43 earth colour. A modeller has plenty of leeway in deciding colours.
