What is thrust of your Navier engine? Is pressure fed or turbopump. I'm guessing electric if turbo given its smaller than Rutherford.

Its definitive thrust is still being evaluated at the moment to optimize our launcher performances.
We are happy to announce that we have doubled Zephyr's payload capacity in LEO and SSO ! With this performance improvement, Zephyr will be able to respond more efficiently to our customers' needs. #Zephyr #LaunchingPioneers
Are these new capability numbers still accurate?80kg to 550km LEO70kg to 550km SSO
And a second question; any news on funding (for engine development/qualification)?
Too much bureaucracy and dawdling in the Flag of European Union Space industry?Flag of Germany startup @isaraerospace asked DLR Lampoldshausen to test their rocket engine. Nine (!) months later they got "vague reply".So they went to Flag of Sweden Esrange instead, which was much more forthcoming
... in line with ESA’s Agenda 2025 vision of developing an increasingly autonomous and commercially robust European space capability, ESA is also assessing opportunities to exploit so-called microlauncher services currently under development by private companies in Europe.“We are requesting European companies working on microlaunchers to give us robust technical information about the state of their developments” says Mr Neuenschwander.The objective, he adds, is to make sound proposals about their potential to support European institutional missions to the ESA Council at Ministerial level, to be held in November 2022. Those proposals may include a request to initiate a competitive selection process for a prize of a microlauncher service to launch an ESA mission, potentially in 2024.“With a realistic view of development milestones and associated launch dates, we allow European microlauncher services companies to qualify and compete for this individual launch of an ESA mission,” says Mr Neuenschwander.He adds: "ESA's Space Transportation role is to safeguard Europe’s independent access to space, enable activities in space and soon, offer return-to-Earth capability.”
1000kg class LVs could handle most of Soyzu payloads as it does lot ride share for smallsats. Smaller LV maybe slightly dear per Kg but give customer more flexibility.
Pleas God no micro launcher based on Vega it adds no industrial knowledge I would prefer two micro launcher in HER One using methane the other using propane so people get experience using the fuels .
Over the weekend, Belgian business news outlet L'Echo published a revealing conversation with ArianeGroup CEO André-Hubert Roussel. It should be noted upfront that my version of the article has been Google translated from the original French. This obviously does mean that there may be subtleties lost in translation.In the article, the ArianeGroup boss took aim at the numerous launch startups around Europe, decrying the fact that these companies were pulling resources away from Ariane. Roussel took aim at the German microlauncher companies Rocket Factory Augsburg, Isar Aerospace, and HyImpulse in particular, although he did not name them directly.
ESA Boost! for RFA One Launch ServicesQuoteRocket Factory Augsburg (RFA), a German startup developing the three-stage RFA One orbital launch vehicle designed to operate at a high cadence, has received a contract worth €11.72 m from ESA's Boost! commercial space transportation services programme.

Slight update to my European launch vehicle graphic. I have added @Avio_Group's unnamed next-gen launch vehicle and the @PangeaAerospace aerospace Meso launch vehicle. I may make a version of the graphic available in my soon-to-be-launched European Spaceflight store.
