This document discusses Thales' activities in integrated air and missile defense (IAMD) and proposes networked fire control sensor clusters as a potential European/transatlantic contribution to IAMD. It outlines Thales' IAMD systems and capabilities, the evolving threat, and examples of dual medium-range IAMD systems. It also reviews NATO studies on multifunction radars and sensor networking, technology trends, and how sensor clusters could enhance interoperability and system resilience by exchanging resources and services in real time below the NATO C4I level. The objective is to study local sensor/weapon clusters for additional netcentric missile defense data exchange.
