    2. 2 Topics for Discussion Use of Submarine WGS SHF Capability with XTAR Use of IRIDIUM for Comms at Speed and Depth (CSD)

    3. 3 Submarine Operational Scenarios with Commercial SATCOM 4 simultaneous submarines operating dispersed in Med, CENTCOM, North Atlantic or other region covered by XTAR 24/7 coverage required Case 1: Four 2-way 256kbps Case 2: Two 2-way 256kbps Two 2-way 512kbps Case 3: Four 2-way 512 kbps

    4. 4 Notional WGS/XTAR Coverage

    5. 5 Notional Submarine XTAR Architecture

    6. 6 Submarine Current and Planned X-Band Equipment

    7. 7 Topics for Discussion Use of Submarine WGS SHF Capability with XTAR

    8. 8 CSD’s Incremental Capability RDC – Rapid Deployment Capability RTT – Rapid Technology Transition FCT – Foreign Comparative Test ACTD – Advanced Concept Technology Demonstration LBUCS – Low Band Universal Communication SystemRDC – Rapid Deployment Capability RTT – Rapid Technology Transition FCT – Foreign Comparative Test ACTD – Advanced Concept Technology Demonstration LBUCS – Low Band Universal Communication System

    9. 9 Tactical Paging Buoy (TPB) Buoy launched by a Submarine Buoy receives Iridium SATCOM broadcasts from shore site/ networks and converts signal to “Deep Siren” acoustic transmission, an acoustic coded pulse to relay information to submerged Sub TPB provides Buoy to Submarine communications only (one-way -- ship (or shore)-to-submarine)

    10. 10 Tethered Expendable Communications Buoy (TECB)- Iridium

    12. 12 Summary XTAR potential option to supplement submarine MILSATCOM Shore site requires additional investigation No XTAR specific inboard submarine modifications required IRIDIUM Provides a unique capability with world wide coverage and on-demand service Transition From IRIDIUM back to MILSATCOM (MUOS) as IRIDIUM reaches end-of-life
