Design & Analysis Alternatives Generation Modeling & Analysis Decision Making Problem Definition Alternative Scoring Needs Analysis Decision Objectives Analysis Implementation Planning for Action Execution Assessment & Control Systems Engineering Design Process Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  3. SEA-8 Problem Statement • SEA-8 .. design a system that denies enemy undersea forces (submarine and UUV) effective employment against friendly forces within the littorals during the 2025 timeframe. Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  4. Problem Definition Phase Problem Definition Needs Analysis Objectives Analysis • Needs Analysis • Primitive Need • Stakeholder Acknowledgements • System Decomposition • Input-Output Modeling • Functional Analysis • Requirements Generation • Effective Need Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  5. ASW Timeline 3/10/30 30 Days Denial sustained for follow-on actions 10 Days Seize the Initiative 72hrs Begin ASW Operations 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  6. Objectives Analysis Phase Problem Definition Needs Analysis Objectives Analysis • Objectives Analysis • Functional Objectives • Measures of Effectiveness • Measures of Performance • Performance Goals Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  7. Scenario Building Coastal Choke Point Passage Defense of Island Nation Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  8. SEA-8 Defined Alternatives • Littoral Action Group (LAG) • DD(X), LCS, SSN, MH-60 • Total Ship Systems Engineering (TSSE) – Sea TENTACLE • Host ship, UUV, USV, UAV, Stationary Bottom Sensors • Tripwire • UUV, Rapidly Deployable Stationary Bottom Sensors • War of Machines • UUV, Recharging Stations • Floating Sensors Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  9. High-level Model Development OUTPUT DATA Reliability discrete event simulation models Logistics analytical models OVERALL SYSTEM PERFORMANCE High-level Entity Based Model C4ISR analytical models Sensors physics based models Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  10. ASW Results, Insights and Recommendations NO PERFECT SYSTEM • Scenario variables were the key factors • Each alternative studied had weaknesses • Differences between alternatives were significant • “Best” solution might be a tailored mix Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  11. ASW Results, Insights and Recommendations REACTION TIME • Enemy submarines are vulnerable in restricted waterways • Enemy timelines are unpredictable • Quick reaction systems hedge uncertainty • Strategic air least sensitive to enemy initiative Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  12. ASW Results, Insights and Recommendations PRESENCE • Pervasive persistence is the goal • Traditional methods • Non-traditional methods Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  13. ASW Results, Insights and Recommendations KILL-CHAIN TIMELINE (KCT) TRADEOFFS • Traditional methods require short KCTs • Non-traditional methods afford longer KCTs • Standoff weapons systems more easily used if longer KCT are allowed Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  14. ASW Results, Insights and Recommendations UNDERSEA JOINT ENGAGEMENT ZONE (UJEZ) • Cooperative mix of assets unlocks future ASW force capabilities • Future ASW forces may require the establishment of the UJEZ • Low false positive and low fratricide rates are required Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  15. ASW Results, Insights and Recommendations RECOMMENDATIONS • Research • Follow on study • Development • UUVs • Rapidly deployable sensing grids • Common undersea picture • Autonomous recharge/replenishment systems Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions

  16. ASW Results, Insights and Recommendations RECOMMENDATIONS • Tactics • Strategic air • JSOW like systems to deliver ASW assets • Doctrine • Evolution from waterspace management and PMI to UJEZ Needs Analysis Obj Analysis Alt Generation Modeling Analysis Conclusions
