SSN(X) Concept Design Expression of Interest

The U.S. Navy’s Submarine Programs office is seeking non‑proprietary expressions of interest (EOI) from qualified vendors to submit concept designs that leverage advanced “Super Intelligence” for the upcoming SSN(X) system arrangement. This pre‑solicitation notice invites companies to demonstrate capability in innovative submarine design, risk reduction, and integration within a hydrostatically balanced whole‑ship concept. Interested firms must submit a brief EOI that includes company details, capability summary, and status as a traditional or non‑traditional defense contractor. The deadline is midnight Eastern Time on 6 Nov 2026, after which the Navy will issue a formal Area‑of‑Interest (AOI) notice. • Required EOI content: company name & CAGE, point‑of‑contact, short interest statement, contractor type, and capability description (3‑5 sentences). • Submission method: email to the Government Points of Contact (David Radell and Kathleen Dwyer). • No commitment or reimbursement for submitted information; participation is voluntary. • This is an “Other Transaction” under 10 U.S.C. § 4022, not a traditional procurement.
