M&S LevelsOperationalEmploymentUNCLASSIFIEDBuilder Overview

Operational Employment• Use Statistical Probabilities to Populate Discrete EventSimulation– Allow Accurate Assessment of Improvements in Loss of LifeDuring Campaign Due to New DoD EW Technology• Campaign and Mission– Discrete EventSimulation– Represent ComplexTactical Problems– Simulate Multiple MissionsWhere Individual EventSimulations at Mission LevelProvide Probability of Effectiveness• Potential Models– Joint Integration Mission Model (JIMM)– EADSIM– Naval Simulation System (NSS)JIMM SnapshotJuly 2009UNCLASSIFIEDEW M&S – Engineering Builder to Campaign Overview

• Bottom Up V&VVerification & Validation– Employ V&V From Component to Campaign Predictions• Components with Specific Lab Tests– Important to Validate Components to Ensure Engagement Modeldoesn’t have Multiple Component Models Offsetting Each Other– Example» Optimistic Antenna Pattern – More Gain than Reality» Pessimistic EW System Model – Less Power Out than Reality• Engagement with Lab and Open Air– Development Test (DT) Events• Mission with Lab and Open Air– Operational Test (OT) Events• Campaign with Open Air• Must Engage Test Leads to Ensure Proper Data isCollected During EventsJuly 2009UNCLASSIFIEDEW M&S – Engineering Builder to Campaign Overview

Recommendations• Standardize on Modeling Framework• Provide Funding for Maintenance of Models andFramework• Mandate Future EW System Model DevelopmentDuring and after System Design and Development(SDD) Phase of DoD Acquisition– Needs to be Developed to Adopted StandardJuly 2009UNCLASSIFIEDEW M&S – Engineering Builder to Campaign Overview

Conclusions• Current M&S Tools Meet the Need at Each Levelbut Require Some Additional Integration at theMission to Campaign Level• Will Provide More Accurate Assessment of FutureEW Systems to the BattlefieldJuly 2009UNCLASSIFIEDEW M&S – Engineering Builder to Campaign Overview
