• Support development of Concept Plan (CONPLAN) materials, Table-Top Exercises (TTX), wargames, and select experimentation projects using AFSIM-based modeling and simulation (M&S) products.
• Align all scenarios with core mission areas, including representations of Golden Dome and Border missions.
• Develop realistic representations of space, air, land, and sea platforms, including sensors, communication links, and behavior models.
• Implement Behavior and Agent Modeling (BAM) techniques and utilize Monte Carlo methods for scenario execution.
• Save scenarios, platforms, and related objects in a data repository to ensure standardization and future reuse.
• Develop interfaces for import/export between AFSIM and other software entities
• Document interface designs and produce user instructions.
• Run AFSIM simulations in support of N&NC analysis tasks and overall M&S efforts.
• Build and execute AFSIM scenarios for CONPLAN development, TTXs, wargames, and experimentation projects as tasked.
• Prepare and deliver data outputs, written reports, and briefing products as required by the Government.
