This is a Justification and Approval (J&A) document for the U.S. Department of the Navy, Naval Sea Systems Command, Shipbuilding Contracts Division. The document seeks to modify Contract No. N00024-19-C-2216 with Thomas-Sea Marine Constructors, LLC (TMC) to add approximately [redacted] hours for Special Studies and Additional Government Requirements (AGR) for the design and construction of NAV Class ships. The contract modification will extend performance from January 2025 through September 2026.

The justification emphasizes that TMC is the only qualified source capable of performing these efforts due to their extensive knowledge of the NAV Class ship design and construction. The document explains that qualifying another source would require approximately one and a half years of additional time, increase costs, and potentially disrupt current construction schedules. The Naval Sea Systems Command has determined that using a sole source approach with TMC is the most efficient method to meet the agency's requirements, with the Contracting Officer certifying that the anticipated costs will be fair and reasonable.
