Title III of the DPA provides various financial measures, such as loans, loan guarantees, purchases, and purchase commitments, to improve, expand, and maintain domestic production capabilities needed to support national defense and homeland security procurement requirements. Title III also authorizes Federal Government procurement and installation of equipment in plants, factories, and other industrial facilities owned by the Government or private persons. A typical Title III project is focused on increasing production capacity and reducing production costs for new, state-of-the-art technologies needed for military and homeland security purposes.

DOD is the only federal agency with an active Title III Program, but, from time to time, other departments and agencies have partnered with DOD in sponsoring individual Title III projects. The authority to undertake Title III projects is delegated, in E.O. 13603, to federal agencies, including DHS, engaged in procurement for the national defense.
