| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Stainless Steel (stainless_steel) | enabling | 68% | expert_inference | Stainless Steel provides a capability that enables this technology without being the only possible path. |
|
| Advanced Chemistry (advanced_chemistry) | enabling | 68% | expert_inference | Advanced Chemistry provides a capability that enables this technology without being the only possible path. |
|
| Jet Aircraft (High-Speed Flight) (jet_aircraft_high_speed_flight) | commercial_or_scaling_dependency | 74% | review | Jet-engine and gas-turbine demand drove superalloy improvement and deployment; aircraft are an application and scaling context, not a material prerequisite. |
