New Japanese Type 2 Single-Engine Fighter, TOJO
1. Informational Intelligence Summaries No. 43-49 of 10 November and No. 43-51 of 30 November contained certain previously known details of the Type 2 single-engine fighter TOJO. A recent report has been received that includes sketches and drawings of this aircraft, these being reproduced in Fig. 6. Data supplementary to that given in the Summaries mentioned above follows:
a. Wing is constructed in six sections. It is joined by bolted-type joints at the centerline, and at points 6 1/2 ft., and 12 ft. 11 in. outboard from the centerline, the last-named being the tip attachment. Each wing, therefore, is composed of sections 6 1/2 ft., 6 ft. 5 in. and 2 ft. 8 in. long. No protective or de-icing devices are on or in wing leading edge.

b. Fowler type flaps are operated hydraulically as well as the engine cowl flaps. A hand hydraulic pump is incorporated in the system as well as the engine-driven pump.
c. Cockpit is high-set over wing, with little streamlining.
