With 6x more propellant and 4x the power of today’s Dragon spacecraft, SpaceX was selected to design and develop the U.S. Deorbit Vehicle for a precise, controlled deorbit of the @Space_Station
Looks like there will be 30 draco engines on the back of that thing. Pretty Kerbal!
Edit:
For $0.8 billion I’d design a new engine! (Would have to learn rocket science first but I’d be able to afford the best teachers, so doable.)
