The Department of Defense, specifically the U.S. Army Combat Capabilities Development Command Chemical Biological Center (DEVCOM CBC), is soliciting proposals through a Broad Agency Announcement (BAA) for innovative solutions in chemical, biological, radiological, nuclear, and explosive (CBRNE) defense capabilities. The BAA invites participation from a wide range of eligible sources, including educational institutions, nonprofit organizations, and private industry, to develop technologies such as sensor systems, aerosol technologies, and decontamination methods. This initiative is crucial for enhancing national defense capabilities and ensuring the Joint Warfighters' effectiveness on the battlefield and in homeland defense.
