Unsensored systems: what predictive maintenance changes for readiness

TL;DR: Decades-old military platforms still carry critical unsensored components that create readiness blind spots, prolong diagnostics and increase mission risk because traditional health monitoring only covers directly instrumented systems, according to Shift5. The operational lesson is that maintenance visibility must extend beyond what is natively sensed, or degradation will continue to surface only after failure.

Key questions

Q: What breaks when critical assets are monitored only through proxy telemetry?

A: Proxy telemetry can reveal drift, but it cannot guarantee that every failure mode is visible.

Q: Why do blind spots in operational monitoring increase mission or business risk?

A: Blind spots delay detection, which extends the time between deterioration and intervention.

Q: What are the signs that predictive maintenance is missing important failure modes?

A: Common signs include repeated surprise failures, long diagnostic cycles, and sensor data that looks healthy even as performance declines.

Practitioner guidance

• Define the monitored boundary for every critical system Inventory which components, identities or assets are directly sensed and which depend on proxy inference, then document the blind spots that remain outside native coverage.
• Use proxy telemetry to rank degradation risk Correlate surrounding sensor behaviour into a drift model so maintainers can prioritise inspection where the evidence suggests hidden deterioration is most likely.
• Tie anomaly thresholds to response workflows Convert near real-time alerts into named maintenance actions, ownership and escalation paths so a signal leads to repair, replacement or deeper forensic review.

Bottom line: The article shows that unsensored components create blind spots that can delay maintenance and increase mission risk.
