How Much Did SpaceX Spend to Develop Falcon 9?

David Senra, reading Max Olson, says a NASA study found SpaceX developed Falcon 9 for roughly $440 million. The same work with traditional contractors would have cost 3 to 10 times that amount.

SpaceX concluded that atoms were cheap and process was expensive, so vertical integration followed. You cannot negotiate a 10X cost reduction with suppliers who have profits baked in at every tier. By building 80% of its hardware internally, engines, structures, avionics, software, and key ground systems, SpaceX collapsed the traditional aerospace stack and kept only raw materials and commodity parts outside. When several tiers each add 15% margin, total cost multiplies through the layers. Suppliers kept quoting prices and timelines incompatible with SpaceX cost targets. An engineer who needs to change a bracket, weld, or circuit board works in the same building as the manufacturing engineer, so materials, jigs, and processes can evolve on the scale of weeks instead of multi-year supplier retooling.

Vertical integration concentrates fixed costs. Owning the factory, the machines, and the staff means losing money every second they are not building something. At the traditional launch cadence of two to four vehicles per year, in-house manufacturing is a liability.
