NATO Interoperability

▸Spain is treated as a NATO member-state profile with full Alliance political status and integrated planning relevance.

▸The profile emphasizes coalition interoperability, command-and-control compatibility, equipment commonality, and theatre-specific contribution rather than national threat assessment.

▸Registry-linked systems are drawn from the local Equipment Registry where a representative platform entry exists; non-linked systems remain listed as country equipment references.
