An Overview of the Effectiveness ToolBox (ETB)

ETB is a weapon effectiveness model developed by the Lethality and Weapons Effectiveness Branch (H32) of the Naval Surface Warfare Center Dahlgren Division (NSWCDD).  ETB is a time-based, Monte Carlo simulation in which objects move in a 3-D virtual world and interact using analytical, numerical, and empirical methodologies. ETB allows the user to model scenarios of varying complexity – from a simple target vulnerability analysis involving a single fragment interacting with a target to a highly complex effectiveness analysis involving multiple weapons and multiple targets.  ETB uses a graphical toolkit to visualize the underlying calculations of the model.  This visualization capability greatly simplifies the setup and understanding of the model results.  The graphics toolkit is combined with various methodologies for modeling target vulnerability and weapons effectiveness.  ETB has evolved to support a number of different weapon types, including blast-fragmentation warheads, gun systems, and high-energy laser systems.  Methodologies have been added to address damage due to direct hit, blast, fragment impact, projectile impact, and laser beam energy.
