Concerns about the financial solvency of the Defense Industrial Base (DIB) and the stability of supply chains that are key to national security prompted the U.S. government and Department of Defense (DoD) to make policy changes and investments to support the DIB during the coronavirus disease 2019 (COVID-19) pandemic. The health of small businesses was of particular concern because these companies can have limited visibility in supply chains and are often more vulnerable to financial disruptions. In this exploratory analysis of Paycheck Protection Program (PPP) data, the authors summarize investments in DIB businesses that received assistance during the early months of the pandemic (through mid-2020). Descriptive analytics of open source data revealed that the PPP offered financial assistance that reached many small businesses in the manufacturing industry, an important sector for national security supply chains whose production was especially hard hit by the COVID-19 crisis.
