Episode notes
Atoms Are Cheap Process Is Pricey
- SpaceX targeted launch cost itself, treating it as a variable rather than a fixed aerospace constraint.
- Elon Musk traced rocket prices to 2% materials and 98% process, markup, custom work, and expendability.
How SpaceX Crushed Supplier Prices In House
- SpaceX rebuilt overpriced parts from scratch instead of accepting vendor timelines and prices.
- A Falcon 1 actuator quoted at $120,000 and 18 months was built in-house for $3,900; Mueller’s team also made a critical valve themselves.
Vertical Integration Turned Cost Goals Into Reality
- Vertical integration let SpaceX capture savings that suppliers would absorb through stacked margins and slow handoffs.
- By making 80% of hardware internally, it developed Falcon 9 for about $440 million versus NASA’s estimate of 3 to 10 times more traditionally.
