Austal USA launches Digital SEA secure additive manufacturing software platform hosted by US Navy

Austal USA has officially launched Digital SEA (Secure Exchange for Additive), a secure software platform designed to facilitate additive manufacturing (AM) data exchange across the maritime industrial base. Developed in collaboration with software partners Sabel Systems, C3 AI, and EdgeTI, the platform is hosted by the US Navy to support critical submarine and surface vessel programs. Austal USA interim president Gene Miller and Program Manager Madeleine Locke confirmed the platform aims to unify the digital supply chain, building upon the company's existing work in developing over 70 AM parts currently scheduled for fleet installation. The platform serves as a digital clearinghouse to manage the secure transfer of complex print files and technical data between the Navy and its distributed network of suppliers.

This launch addresses a critical bottleneck in the defense sector: the secure, high-speed distribution of digital manufacturing assets within a highly regulated and fragmented supply chain. While many AM software solutions focus on build preparation or machine monitoring, Digital SEA targets the organizational layer of the Industrial Internet of Things (IIoT) by providing a secure environment for multi-party collaboration. By integrating with the Navy's existing efforts to establish an AM Center of Excellence in Virginia, Austal USA is positioning itself as a central orchestrator of digital maritime manufacturing. This move moves the industry beyond isolated hardware deployments toward a networked, software-defined production model capable of supporting large-format AM and distributed redundancy for national security assets.

For the maritime industrial base, the success of Digital SEA depends on the seamless adoption of these protocols by tier-2 and tier-3 suppliers who may lack advanced digital maturity. Austal USA must now demonstrate that this platform can maintain rigorous cybersecurity standards while reducing the lead times for critical components in the Virginia- and Columbia-class submarine programs. The immediate focus will be on the platform's ability to scale the existing catalog of 70+ parts to a wider array of mission-critical components across the US Navy's surface and subsurface fleets.
