The purpose of this project was to explore the benefits of using a combination of additive manufacturing AM, Performance-Based Logistics PBL, and Open Systems Architecture OSA to mitigate the risks of limited key ship components for the Zumwalt-class destroyer DDG 1000 program. Specifically, this project was focused on current industrys capability for AM and the implementation of AM in the near future. Research was conducted in three phases. First, this research reviewed the problems and challenges within the defense industry. Next, this research reviewed the previous research on intellectual property IP concerns with AM particularly, insourcing versus outsourcing and the latest AM applications in the marketplace and defense industry. Finally, this research focused on DDG 1000 program documents, including the Acquisition Strategy AS, the Life-Cycle Sustainment Plan LCSP, and a Diminishing Manufacturing Sources and Material Shortages DMSMS analysis. By conducting a comparison of DDG 51 and DDG 1000 and analyzing an AM arrangement among Airbus, Systemanalyse and Programmentwicklung SAP, and United Parcel Service UPS, this research concludes that the government can use AM, with a properly structured PBL arrangement and OSA, to substantially mitigate risks, lower operation and support O and S costs, and effectively improve system readiness.
