As the naval battlespace evolves, ship self-defense systems must adapt to new, asymmetric threats including fast attack craft, UAV swarms and anti-ship missiles. The Directed Energy Weapon (DEW) program is one such effort that aims to combat these threats while operating at a significantly reduced cost per shot. Evaluating the performance of this system from the ship-level perspective is critical to progressing toward this goal. Therefore, a new modeling environment is required that will enable such analysis. This project focuses on developing agent-based weapons and sensor models for the DEW system and integrating them into a modeling & simulation environment. Selected arsenal options are run through engagement scenarios that include geography, atmospheric conditions, and threat types to evaluate mission effectiveness and cost. The weapon models include the Navy's Laser Weapon System (LaWS), conventional Close-In weapon systems (CIWS) and missile systems, allowing for comparison between engagement methods. The laser is unique in its dependence on atmospheric conditions and required time on target, which necessitates its pairing with a high-fidelity sensor model. Composed of radar and electro-optical/infrared packages, the sensor model handles detection and tracking of targets within the engagement scenario. This environment allows for analysis of new threat scenarios to better inform the design and integration of DEWs into future fleet architectures.
