The Department of War (DoW) Office of Industrial Base Growth (IBG) in conjunction with its marketplace manager, the Applied Research Institute (ARI), and supported by the Washington Headquarters Services Acquisition Directorate (WHS/AD), is initiating this long-term, open call for solutions to support the DoW in advancing the development, demonstration, scaling, testing, procurement, production, fielding, and sustainment of hardware, software, systems, subsystems, components, materials, manufacturing capabilities, workforce development, and service solutions that strengthen the defense industrial base and deliver critical capabilities to the Warfighter.

This initiative, entitled the “APEX Arsenal Solutions Marketplace (AASM)” will solicit, collect, assess, and curate solutions supporting critical production and sustainment, commercialization and scaling of emerging technologies, domestic workforce development, critical materials and components, weapon and space systems, and broader industrial base readiness, and make those solutions available for procurement through rapid acquisition pathways.
