This is a very key point.
The Falcon 9 isn’t cheap because of reuse (yet). It’s cheap because of mass manufacturing. The Rs-25 engine costs over $100m each, Ariansoace Vulcains around $20M, typical large rocket engines over $10M.
SoaceX Merlin costs about $200,000 each to make. The Raptor will be close to that. Thats why SpaceX can pursue the large number of redundant smaller engines design strategy so successfully.
Reuse has lowered Falcon 9 costs internally, and increased its private discounts, but not it’s public pricing. When the cost benefits of reuse finally cascade through public pricing and through the entire stack with Starship, you have a SuperHeavy launch system putting 150 tons in orbit even cheaper than a single Falcon 9 launch.
For comparison, the Shuttle was over $40,000 per pound to Orbit. The SLS will be around $10,000/lb to orbit if you don’t count developmental costs at least 3x that.
The Falcon 9 is $1,500/lb to orbit, and Falcon Heavy $1,100/lb to orbit. Starship will lift more payload to orbit than the SLS, and 4x as much as the Shuttle, for between $100 and $300 per pound.
- mschuster91 6y ago> Reuse has lowered Falcon 9 costs internally, and increased its private discounts, but not it’s public pricing It's not just a discount - it is the reversed equivalent of banks charging interest for a loan due to failure risk. Private customers getting discounts accept the increased risk that some re-used part fails. Essentially SpaceX has managed to have their r&d subsidized by paying customers instead of having to borrow money, launch dummy payloads and pay the money back.
