AI Contract Overview

The U.S. Navy, through NAVSEA, is conducting market research under a sources sought notice to identify qualified contractors capable of providing emergent submarine repair services for nuclear-powered submarines, special mission submersibles, nuclear-powered moored training ships, and associated support facilities. This notice is not a solicitation and does not obligate the government to issue a contract or order; no payment will be made for responses or work performed in anticipation of future procurement. The requirement, anticipated to be fulfilled via a Basic Ordering Agreement with an ordering period from May 2027 to May 2032, demands specialized technical, engineering, and nuclear-related labor with unique capabilities not widely available in the commercial market. Due to the sensitive nature of the work, contractors must be capable of handling, processing, and storing Controlled Unclassified Information and must demonstrate compliance with Cybersecurity Maturity Model Certification Level 2. Respondents must provide basic company information including name, physical address, CAGE code, Unique Entity Identifier, business size status under NAICS code 336611, small business classification if applicable, approximate employee count, and contact details. Crucially, all submissions must include details on current CMMC Level 2 compliance and nuclear qualification or certification status to demonstrate the ability to safeguard sensitive data and perform nuclear-related tasks. Responses must be submitted electronically by June 5, 2026, and will become government property; proprietary markings must be applied to any sensitive information, though submission does not guarantee protection from disclosure. NAVSEA is particularly seeking to identify small business interest, though the requirement may ultimately be awarded as a limited competition between only two nuclear-qualified shipyards: General Dynamics Electric Boat and Huntington Ingalls Industries Newport News. Subcontracting opportunities are not administered through this notice and must be pursued directly with those two entities.
