The Engineering, Propulsion Plant and Ship Systems – COLUMBIA is an engineering and design organization that leads innovative development of propulsion plant systems, ship systems, structures, arrangements, and shielding for the COLUMBIA Class. The directorate continuously improves its products and processes to deliver high‑quality engineering solutions that meet or exceed customer needs, while providing on and off-site support to the shipyard throughout submarine construction. Interns within this organization contribute to both design-focused and waterfront-focused engineering activities, supporting construction, technical troubleshooting, and fleet readiness.
This directorate is responsible for developing and analyzing propulsion plant fluid systems, structures, and arrangements, as well as delivering timely, accurate, construction‑support engineering products that increase shipyard productivity and prevent unnecessary work or rework. Engineers and designers also provide fleet support to commissioned COLUMBIA Class submarines and work directly with shipyard personnel, vendors, and Navy stakeholders to resolve technical issues across all construction and testing phases.
