Strategic Bottlenecks in Electro-Optical and SAR Supply Chains

The strategic environment of European defence is entering a phase in which space-based intelligence has become a structural requirement rather than a technical enhancement. The rapid shift toward electro-optical and SAR constellations reflects a broader realignment: NATO and EU planners now treat orbital sensing as the backbone of situational awareness, operational autonomy and crisis responsiveness.

Recent conflicts exposed how fragile this backbone remains, revealing gaps in imaging capacity, dependencies in upstream supply chains and constraints in launch, processing and exploitation.

This analysis answers: Why has space-based electro-optical and SAR intelligence become a structural requirement rather than a technical enhancement for European defence? Where are the strategic bottlenecks in imaging capacity, upstream supply chains, launch, processing and exploitation of EO and SAR constellations? How do NATO and EU planners treat orbital sensing as the backbone of situational awareness and operational autonomy? What dependencies and constraints revealed by recent conflicts threaten Europe's electro-optical and SAR supply chains?
