Last thread I could find on the FLPP is 9 years old!

The European Space Agency has published a tender aimed at beginning the development of a very high-thrust rocket engine for future heavy-lift launch vehicles.

Raptor class engine, probably intended for EHLL designs?

Here's the actual tender:

https://esastar-publication-ext.sso.esa.int/ESATenderActions/details/71553

"for the heavy liftcapability" implies that this tender is, indeed, to power something like EHLL.

However, it could also serve for other purposes. It's similar in thrust to DLR's "SpaceLiner Main Engine", which they proposed would power a large winged RLV. It's also about twice the thrust of a Vulcain or Prometheus engine, so it could power a future upgrade of Ariane 6.

In any case, the tender serves "to elaborate further the concept and de-risk the enablingtechnologies and infrastructures at the basis of such a very high thrust propulsion building block". In other words, "write a few papers". Don't expect any actual hardware until money is allocated at the 2025 ministerial council..

"Open To Tenderers From
BE+CH+ES+FR+IT"

That seems to be missing some big countries, is it normal?

Although right now, I don't know any other 250t thrust class engine development in Europe beside the current CNES-Arianegroup projects ("Upscaled Prometheus" and Staged combustion projects, the later being supposed to have a subscale demonstrator firing... by 2025) which are in France.

Not sure where such projects would be tested, the PF50 is supposed to be modified later this decade to handle 250t thrust engines, but that's NET 2028. Are there other large test benches in construction?
