The Iceland Air Defense System: state-of-the-art C4I communications for a changing world

Three separate and distinct types of change are occurring which affect C⁴I communications. These are: (1) a moderation of US attitudes toward eastern Europe, (2) a shrinking defense budget, and (3) rapidly changing technology. The Iceland Air Defense System (IADS) telecommunications system (ITS) responds to each of these rapidly changing arenas. The ITS transports and manages three general types of circuits: off-island circuits, long-haul interconnectivity circuits among IADS facilities, and intra-southwest area circuits. The ARC design of the IADS communications system has been based on the maximum use of state-of-the-art commercial-off-the-shelf equipment and subsystems integrated to meet the IADS requirements. The IADS communications subsystem processes three distinct circuit types: ground-to-ground voice, ground-air-ground voice, and various types of data circuits
