Looking for specific mod with engines

[Nezerroth]

I remember installing a mod quite some time ago, it had eigines and other parts, particulary two variations of nukes. One was fatter 2.5m nuke, I think it's called fat moon, and quad-nuke, sort of a nerva with spherical tanks bundled together. I liked the models, there were also huge engines and stages, and everything was well balanced for gameplay. Couldn't find it here or thorough googling. Anyone can help?

Modular Rocket Systems?

Sounds familiar, but I can't seem to find those. I also just found some old screenshots from 2014, the mod may be outdated or parts no longer supported.
