When checking the description of the Hyperdrive engine in the research menu, I missed the Lunar Guardian. It uses the hyperdrive engine I think, but that's not mentioned in the description. So maybe you find some minutes to update this and add the Lunars to the text.

I think that's a good idea. Also I'd have to check, but I don't think it lists which engine impacts the Elite Recyclers.

That's correct, the Elite Recyclers are not listed. There should be a more specific descriptive writing for the combustion drive as it mentions the small and large cargos but only recyclers, not the elite ones.

Thx for the reference, SilverVixen.

By looking at the tech tree you will found which ship needs which engine and levels needed don't need to go in to any said engine description or for a need to list any ships

Yes, but then any description in the research menu would be obsolete. That's not the point. If the game includes such specific descriptions, these should be complete and correct. It's about a consistent overall appearance of the game.
