Directed Energy Lethality and Collateral Effects Modeling

"The BMDO core Modeling & Simulation software Post-Engagement Ground Effects Model (PEGEM) will be modified to facilitate the study of collateral effects resulting from Directed Energy (DE) weapon engagements of threat missiles. This provides a criticaltool for DE weapon lethality and vulnerability analysis and the associated military utility assessment. While maintaining PEGEM configuration control, modularity, and HLA compliance, the code will be modified to provide new capabilities for the analysisof ascending threats (particularly boost-phase missiles), tracking of damaged reentry vehicles (providing options for fuze and arming condition, degraded ballistic behavior, etc.), slow release of chemical/biological agent or submunitions from damagedwarheads, and tracking cruise missiles that follow prescribed non-ballistic flight paths. This modification of PEGEM will greatly enhance the capability of DE weapon analysts (SBL, ABL, etc.) to gauge the military utility of their weapon systems byanalysis of the unintended ground effects resulting from threat missile intercept. This issue has proven to be of very high importance for KE interceptor programs, critical to continued progress through acquisition decisions and review, but the capabilityis presently entirely lacking from the tool kit of the DE weapons analyst.The improved PEGEM tool will support all the armed services, including their industrial contractors, and those civil gove
