The Bottleneck Scorecard: the Full Ranking
Which parts are the chokepoints, ranked, and how robust is the ranking?
Chapter summary
on Setcoin's default weights five parts score as critical (75 or above): merchant optical terminals (83), solid rocket motors (81), launch slots (77), rad-hard processors and FPGAs (75) and III-V solar cells (75).
Key takeaways
- 1
Five more are serious (64–74): space-grade power switchgear, infrared focal planes, connectors, GaN and GaAs RF parts, and actuators and nozzles.
- 2
The remaining eight, from carbon fibre to hydrazine, are on watch.
- 3
Optical terminals and rad-hard processors stay in the top five under every weighting Setcoin tested; geography-heavy weights push gallium-dependent parts up and motors down.
