Statement
Demonstrate isolated power trains, black start, representative heat rejection, local repair, and stable operation through injected failures.
Evidence dimensions
- Basis
- normative
- Readiness
- early research
- Confidence
- supported
Assessment rationale
The proposed gate combines demonstrated terrestrial black-start methods, a bounded small-fission ground demonstration, current spacecraft power and thermal practice, and safety-aware operational-technology recovery. It is a GShips test requirement, not a claim that the integrated capability already exists.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
An independently reviewed assurance protocol that demonstrates equal or stronger coverage of isolated generation, representative heat rejection, passive survival, black start, local repair, cyber fault recovery, and repeated injected failures could replace or satisfy this gate.
