| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Orbital Launch Vehicles (orbital_launch_vehicles) | enabling | 68% | expert_inference | Orbital Launch Vehicles provides a capability that enables this technology without being the only possible path. |
|
| Computers (Mainframe/Early) (computers_early) | historical_predecessor | 75% | expert_inference | Computers (Mainframe/Early) is an earlier historical predecessor or foundation, not a one-to-one engineering dependency. |
|
| Process Control Instrumentation (process_control_instrumentation) | enabling | 68% | expert_inference | Process Control Instrumentation provides a capability that enables this technology without being the only possible path. |
