"Are impressing more than DARPA (of what we know)."
Actually, there is one DARPA program that might interest you, it's called DRACO.
The Demonstration Rocket for Agile Cislunar Operations (DRACO) is an under-development spacecraft by Lockheed Martin in partnership with BWX Technologies as part of a DARPA program to be demonstrated in space in 2027. The experimental vehicle is planned to be reusable and will utilize next-generation nuclear thermal propulsion technology and low-enriched uranium.
