elonmusk (7 May 2020). "Starship + Super Heavy propellant mass is 4800 tons (78% O2 & 22% CH4). I think we can get propellant cost down to ~$100/ton in volume, so ~$500k/flight. With high flight rate, probably below $1.5M fully burdened cost for 150 tons to orbit or ~$10/kg" (ทวีต) – โดยทาง ทวิตเตอร์.
"SpaceX Starship Super Heavy and Raptor Engine Evolution, Starship SN-6 Hop, Starlink, SAOCOM 1B" ที่ยูทูบ "Also mentioned was that the propellant for this was intended to be 78% liquid oxygen and 22% liquid methane from this point on."
Michael Sheetz on Twitter: Musk goes into a long explanation of the potential capabilities of the SpaceX Raptor rocket engine (which will power Starship), saying that the company thinks Raptor could achieve a thrust-to-weight ratio of 200.
Elon Musk on Twitter: Max thrust version of Raptor should achieve true T/W > 170. Target is 1.5 ton engine with >260 t-F. Max Isp version should achieve ~380 sec, but T/W probably <120 due to big nozzle. These are just guesses for now.

In a move that would have seemed crazy a few years ago, Mr. Musk stated that the goal of BFR is to make the Falcon 9 and the Falcon Heavy rockets and their crew/uncrewed Dragon spacecrafts redundant, thereby allowing the company to shift all resources and funding allocations from those vehicles to BFR. Making the Falcon 9, Falcon Heavy, and Dragon redundant would also allow BFR to perform the same Low Earth Orbit (LEO) and Beyond LEO satellite deployment missions as Falcon 9 and Falcon Heavy – just on a more economical scale as multiple satellites would be able to launch at the same time and on the same rocket thanks to BFR's immense size.
