The LV-N Atomic Rocket Motor is a low-thrust, high-efficiency rocket engine which is powered by liquid fuel and oxidizer as of 0.18.1. This will likely change to a more realistic fuel source in later versions.


  • The LV-N provides less thrust than almost every other liquid fuel engine (the LV-909 being the main engine with less power). However, it has a vacuum ISP of 800 s, the best in the game of any liquid-fueled engine (only the ion engine is higher). This remarkable efficiency makes it quite popular for transfer and injection stages, where high thrust is unneeded and no atmospheres are present.


Despite the big scary trefoil painted onto the side of this engine, its radioactive exhaust, and tendency to overheat, the LV-N Atomic Rocket Motor is harmless. Mostly.

Yes, I know this is wrong. NTRs don't actually burn fuel and oxidizer, but we don't want to jump into making separate tanks for the two yet.
