From what I've been able to learn about this extraordinary machine, there were no plans to operate the crft om ramjet power alone, but simply allow that excess air beyond the needs, and "swallowing" capacity, of the turbojet to feed the ramjet at high Mach numbers, (i.e. M2+), the two operating together. What I don't understand is the progressive use of a LOWER(!!)-powered ATAR turbojet as a sustainer, unless the descending thrust figures are a "typo". Another question that has intrigued me is the controllability of the ramjet unit itself, which was a major, if not insurmountable, problem for contemporary Leduc in his 022.

I would like to know if the Griffon II ever completed transition from turbojet to ramjet and, if so, what Mach number was reached in tests.

The aircraft was not experimental it was a prototype fighter

The highest mach number achieved by the Griffon II was 2.19

27 October 1958 pilot Andre Turcat set closed circuit speed record of 1,638 kmh.
