Expending the second stage would almost certainly be cheaper per kg than Falcon 9, but I doubt this is still true if you have to expend the booster.
Keep in mind we would have to compare it to the ~20M marginal cost of a F9 launch, not the $70M sticker price that a customer would pay.
- bryanlarsen 3y agoIt might actually be cheaper even if the booster is expended. Falcon9 is estimated to cost about $30M/launch. $20M to build the upper stage, and $10M to launch. Starship is estimated to cost about $100M to build both the booster and the second stage. Add $10M to launch. So 17t/$30M vs 150t/$110M.

- bryanlarsen 3y ago$110M is insane. Anything under $1B seems unfathomable. $25M for a 2MN full flow staged combustion engine seems cheap. SpaceX plans on building them for $250K a piece. They're not there yet, but current estimates of $1M a piece are just as insane.
