GDIT is leading the effort of developing the Joint Effect Model (JEM) for the Space and Naval Warfare Systems Command (SPAWAR). JEM is a web-based software application that supplies the Department of Defense (DoD) with a single accredited tool to effectively model and simulate the effects of chemical, biological, radiological and nuclear (CBRN) weapon strikes and incidents. JEM can provide warfighters with the ability to accurately model and predict the time-phased impact of CBRN and Toxic Industrial Chemical/Material (TIC/TIM) events and effects.
