Starship, but with a third stage…
Powered by the SpaceX Raptor, this huge upper stage will help send over 340t to Low Earth Orbit, 125t to the Moon, and 20t beyond Pluto with a single launch!
Launch simulation by @Phrankensteyn below and specs in the thread.
Design pt.1:
- forward and common dome makes up methane tank, aft dome placed after 3 subsequent ring segments
- holds 540t of superchilled methalox propellant, with tank mass at ~16t
- a large third stage optimizes for heavier payloads, while still being very high energy capable
