French Space Rocket question

I never say it is a novel!

I thought you said the booklet on missiles was boring.

Excerpt from "Evolution of Liquid Rocket Propulsion in France in the Last 50 Years", J. Villain, IAC, 1989


Additional information :
Diamant-Hydrogene was to be Emeraude + stage with H2 engine + stage with H3 engine
Later replaced by
Diogene 1 : P16 + P10 + H3.5
Diogene 2 : P40 + P10 + H3.5
H3.5, also named Onyx (another gemstone), was to use an HM4 engine.

Thanks a lot! Structure seems probably inspired from P16/902.

From a purely technical point of view, October 1968 also represents the arrival of american tooling at Le Haillan's factories enabling far larger nozzle than before, nozzles were one of the more difficult aspect of the development of the booster stages of the M1 and S2 missiles (P16/P10 boosters) both from a structural and guiding (thrust vectoring) point of view, that larger tooling alongside the development of flex-seal bearing nozzles at around the same time (late 68 onward) were basic requirements for making far larger piloted solid rocket motors like that P40/P45.

"the deployment of ICBM on French soil would enable the French to "relate with their own defense"."
Hum, that's one way of saying "paint additional targets on continental France even the chinese can't ignore"
Love the certainty this speaks of the Mirage G4

very good paper, alongside the others by comaero, but since ballistic missile development don't have that many sources, this one is particularly needed; a bit sad there has not been more comprehensive books in 20 years;

Researching about the context behind early hydrogen propulsion, Ballistic missile derived launchers, early observation satellite projects is interesting. If France had , from the mid 60s to early 70s, a National and an European space effort, it looks like it could also have had a true Military space effort, it was not to be.
