Industry Day: Future Submarine Digital Backbone Registration Required by October 16, 2026 Director, Submarine Programs (DSP) seeks industry input regarding the future submarine digital backbone. The Director, Design & Construction (D,D&C) within Direct Reporting Portfolio Manager, Submarines (DRPM Subs) will host a one-day classified Industry Day on November 18, 2026 (9:00 AM EST) at Systems Planning and Analysis (SPA), 2001 N Beauregard St., Alexandria, VA 22311. This event will focus on using digital design in submarine acquisition. Industry input and engagement is needed to turn this plan into executable tasking. The meeting will be held at the SECRET level. Future submarines need a digital backbone that enables maximum system interconnectivity, centralized data storage, and future extensibility. Sustainment, operations, logistics, and condition-based maintenance must be enabled by the Common Computing Environment (CCE). Future submarines require state-of-the-art Data Center technology in a submarine environment, accounting for space, weight, power, and cooling constraints as well as militarization of the technology. This future state also includes connectivity of systems that have not previously been networked. DSP is seeking specific technical solutions and concepts from industry to support the following areas: Software Defined Architecture Common Computing Environment / Data Center Technology Modular Open Systems Architecture (MOSA) Submarine Systems User Needs Hull, Mechanical, & Electrical (HM&E) Systems Agenda Morning Session: The first half of the day will consist of the Government briefing attendees on SSN(X) objectives, schedule, and requirements development, the drivers for a future submarine digital backbone, user needs, and the vision for a submarine platform-wide common computing environment. Afternoon Session: The second half of the day will consist of scheduled one-on-one sessions with the Government, shipbuilders, and UARCs present, allowing Industry to present technical solutions and ideas for the future submarine digital backbone. Note: Do not submit generic capability statements. DSP is only seeking specific technical solutions and ideas for future submarine digital backbone solutions.
