The Navy’s New Attack Submarine Program Office (PMS 351) is seeking industry interest in SSN(X) concept design ahead of a planned competition.[1]

The Navy’s Oct. 30 pre-solicitation says the formal Area of Interest notice could launch as early as next week under Other Transaction authority.[1] The forthcoming opportunity will seek competitive industry concepts to advance a novel SSN(X) System Arrangement Concept Design.[1]

The Navy aims to reduce the technical risk of integrating that arrangement into the submarine’s overall design, described as a hydrostatically balanced Whole-Ship Submarine Concept Design.[1] The scope calls for using “Super Intelligence,” a term the notice does not define.[1]

Responses are due at midnight Eastern Time at the start of Nov. 6, 2026.[2] The request carries no government commitment, and respondents will not be reimbursed for submitted information.[1]

## Why it matters

The request gives traditional and non-traditional defense contractors an early opportunity to flag capabilities for SSN(X) concept work.[1] Skipping this response does not preclude participation in the forthcoming Area of Interest or future engagements.[1]
