TeraFab files
Silicon is the other half of the stack.
TeraFab is not a side factory. It is the compute loop that has to close with Starship, ice, and power — radiation-hard chips in orbit, edge silicon for the machines that build the city, wafers that match the catcher tower.
The loop
Published loads

- 1,000,000 t hardware to orbit
- Wafer starts
- 1M / month at Grimes County
- Rule
- Land the booster or there is no server

Papers on this desk
Two notes hold the TeraFab argument. The backbone is why a terawatt fab exists. The unified machine is why the tower, the wafer, and the robot are one loop.

One Unified Physical Machine
If you cannot land the booster, you cannot launch the server. If you cannot package the chip, you cannot power the robot.

TeraFab Is the Silicon Backbone
Stainless steel makes return impossible until you close the ISRU and compute loop. A terawatt fab is not a chip factory. It is the bridge off Earth’s gravity well.
The same numbers sit in the dossier, next to ice and watts.
