Let me know when you want to revisit the pre-1919 period (perhaps in another thread). The English language resources for French development programs and tactical doctrines are pretty poor.

Hi,
For 1919 there were specifications for 11 categories, including four categories for fighter aircraft:
- C.1 single-seat, high altitude, 240 km/h at 7000 m, ceiling 9000 m
- C.1 single-seat, medium altitude, 270 km/h at 4000 m, ceiling 6500 m
- Cap.2 two-seat fighter and reconnaissance ("chasse et grande reconnaissance"), 200 km/h at 7000 m, ceiling 8500 m
- Can.2 two-seat fighter and night reconnaissance ("chasse et reconnaissance de nuit"), 190 km/h at 3000 m, ceiling 5000 m
Flight range 2h30 in each category. Armament was two front-firing Vickers machine guns on C.1, and additional two turret-mounted Lewis on two-seaters.
C.1 high-altitude and Cap.2 specifications implied the use of the Rateau supercharger, which proved unreliable.

Results of the 1919 fighter programs:
- C.1 medium-altitude: the Spad 20 (already ordered in 1918) and the NiD.29 were selected
- C.1 high-altitude and Cap.2 were cancelled because of the failure of the Rateau supercharger
- Can.2: no prototype was ordered in 1919.

Technical specifications were renewed in 1921, in seven categories (instead of eleven), including two for fighters:

- C.1, any altitude, 240 km/h at 7000 m, ceiling 8500 m, range 3 h.

Numerous prototypes: Bernard AB.10, Buscaylet-De Monge 5.2, De Marçay 4, Dewoitine D.1, Gourdou-Leseurre 30, 31, 40, Hanriot HD.26, HD.27, Letord-Béchereau, Lioré-et-Olivier LeO.9, Nieuport-Delage NiD.37, Spad 81, Wibault 3, Wibault 5
The Spad 81 and Dewoitine D.1 were selected in late 1923.

- Can.2, 200 km/h at 3000 m, ceiling 5500 m

One prototype only: Lioré-et-Olivier LeO.8. It is said that the aircraft manufacturers showed little interest because of the limited production expected.

The category Cap.2 was abandoned but several prototypes were ordered in 1921 for experiments with the Rateau supercharger: Gourdou-Leseurre F (later GL.50), H (later GL.51), Hanriot HD.15, Potez 11, Spad 36.

Thank you for this more extended list.

About the Dewoitine D.1, its early design was based on the 1919 C.1 medium-altitude specifications, but it was ordered by the Army in 1924, answering the 1921 program. The D.8 was a high-altitude version with Rateau.

About the NiD.40 C1, it was originally planned with a Rateau, then built without it. It was modified as the NiD.40 R for altitude records.

About the Hanriot HD.12, I think it was not built to Army C.1 specifications. I have it as a seaborne fighter, competing with a Spad (unsure which) and the NiD.32 for a different 1919 Navy program, asking for a fighter trainer able to take off and land on short platforms. The NiD.32 was retained.

Finally, the Potez XVI remained a project only.
