4. 4 Advanced EHF (AEHF) Architecture AEHF and Milstar Will Operate as an Integrated Network for Users

5. 5 Provides secure, survivable anti-jam, anti-scintillation communications for strategic and tactical users 24-hour low, medium, and high data rate satellite connectivity from 65°N to 65°S latitude worldwide Assured mission-critical strategic networks Low Probability of Detection and Interception Successor to Milstar with greater capacity Backward compatible with legacy Milstar terminals Cooperative agreements with Canada, United Kingdom, and the Netherlands Advanced Extremely High Frequency (AEHF) Satellite Program AEHF-2 in Production

6. 6 AEHF New Capabilities AEHF is More Flexible and Faster than Legacy EHF Systems Increased Coverage, Capacity & Flexibility 10x Improvement in System Capacity 5x Increase in Data Rate 6x Number of Terminals 3x Number of Networks Legacy Terminal Compatible Satellite Command & Control 2x Capacity Backward Compatible for TT&C of Milstar Responsive Mission Planning Centralized Apportionment - Decentralized Control 4x Increase in number of fences Milstar: 100 fences at single level AEHF: 440 fences on three levels Resources assigned to a fence form a “virtual constellation” that cannot be co-opted UCCs have control over their assigned resources AEHF-1 in Acoustic Test

7. 7 Protected Communications - EHF Milstar I/II Survivable comm for strategic mission Up to 2.4 kbps (Anti-Scintillation) Protected comm for tactical users Up to 1.544 Mbps (Anti-Jamming) 40 Mbps capacity per satellite 2 Milstar I & 3 Milstar II on orbit Constellation has provided 50+ years of SATCOM to Warfighters  Advanced EHF(AEHF)  Expanded survivable comm capabilities  Up to 19.2 kbps (Anti-Scintillation)  Expanded protected comm capabilities  Up to 8 Mbps (Anti-Jamming)  430 Mbps capacity per satellite  Four satellites  International program: Canada, United Kingdom, the Netherlands  Backward compatible with Milstar I/II AF Terminals support Protected satellites/services; developing expanded capability through FAB-T Inc 1, GEMS, MMP Upgrade and SMART-T 12

8. 8 Future Technology: Advanced Concepts Group (ACG) 8 Initiates space/ground Capability Insertion Programs (CIPs) Terminals, networks, operations and user domains Leads Pre-Contract activities for all MILSATCOM Products Supports Industry Base Enterprise perspective across components Standards, usage concepts, product alignments Harvests TSAT technology Update/align residual artifacts supported by select supplier talent to new Capability Improvements Supports A5 requirements processes Projected FY10 AFSPC/A5-led Analysis of Alternatives (AoA) and MILSATCOM ICD CDD development - In FY11 More efficient enterprise alignment across MILSATCOM Enables Product Group focus on delivery
