The French President has just announced an investment of 15 million euros in the Prometheus program to accelerate the project by one year.https://twitter.com/Elysee/status/1348976537262043137
If my interpretation is correct the 15mln is for the following:At the Vernon engine test (/product qualification) site, ArianeGroup is going to test a LOxLH2 version of Prometheus in 2021. I wonder how similar this is to the Vulcan 2.2 or 2.3 rocket engines proposed in the past?The LOxCH4 version will most likely still be tested at the Lampoldshausen test site.
Pretty interesting to think they will reuse that old Diamant complex abandonned since, what, September 1975 ? a bit sad the old place had to be razed to the ground, but c'est la vie.
