Only four prototypes of this late-1940s French interceptor were built, and only this one survives. This was the third prototype SO.6020, which was modified as an SO.6025 (and hence re-serialled as 01 ?)
The Ki-79 advanced trainer was developed from the Ki-27 'Nate' fighter by the Mansyu company in Harbin, Manchukuo (Japanese-controlled Manchuria). At least nine Ki-79s ended up in the early Indonesian Air Force. The type was called Nishikoren by the Indonesians.
