From the Overview: "The Defense Production Act (DPA) Title III program is dedicated to ensuring the timely availability of essential domestic industrial resources to support national defense and homeland security requirements. The program works in partnership with the Uniformed services, other government agencies, and industry to identify areas where critical industrial capacity is lagging or non-existent. Once an area is identified, the program engages with domestic companies to mitigate these risks using grants, purchase commitments, loans, or loan guarantees. By executing its mission, the DPA Title III program reduces the nation's reliance on foreign supply chains and ensures the integrity of materials supplied to the American Warfighter. [...] The DPA Title III has three broad focus areas: ' Sustain Critical Production'[:] Programs addressing Industrial Base capability and capacity, whose primary focus is generating and sustaining Material Availability, Reliability, Maintainability, Mobility, Commonality, or Affordability.  'Commercialize Research & Development Investments'[:] Advanced Component or System Development and Demonstration capabilities may require investments to retain a qualitative edge in capabilities and establish commercial viability or scale up. Typical programs may begin with a technology proven capable of producing prototype components or systems in a production relevant environment.  'Scale Emerging Technologies'[:] Emerging Technology Investments enable the rapid and affordable introduction of new capabilities into the organic or commercial marketplace. The technologies may be developed to respond to an emerging threat, a capability gap, or may enhance interoperability or service of existing systems or platforms. The interest in these projects may be the result of revolutionary RD&D [research, development and demonstration] capabilities."
