The Defense Plant Corporation,(DPC), was subsidiary of the Reconstruction Finance Corporation, a government corporation run by the United States Federal Government between 1940 and 1945. To win World War II the United States and its Allied Nations needed massive war production. Many private companies did not have the capital funds to meet the wartime demand for buildings and equipment. Defense Plant Corporation provided financial support to state and local governments. Defense Plant Corporation also made loans to banks, railroads, mortgage associations, and other businesses supporting the war efforts.
