  • Tachikawa Ki-70 reconaissance prototype

 

Design

The Koku Hombu order Tachikawa Hikoki K.K., in March 1939, to design a replacement for the Mitsubishi Ki-46 but the Ki-70 never surpassed the performance of the advanced Ki-46s.

Construction

The Ki-70 was of an all metal construction with control surfaces covered by fabric.

Prototype

The first prototype Ki-70 was finished in February 1943. Flights tests showed that the Ki-70 was very inadequate and performed very poorly. Take offs and landings were unstable.

After the third prototype was still overweight the design was cancelled.

Production

  • Tachikawa Ki-70 prototypes: 3
    • Manufacturer: Tachikawa Hikoki K.K.
    • Production: 1943
