RFI-Universal Modular Mast (UMM) spare parts and cylinders

The Naval Sea Systems Command’s Naval Surface Warfare Center, Philadelphia Division, is pursuing a sole-source Firm-Fixed-Price Indefinite-Delivery Indefinite-Quantity contract with L3Harris Technologies for the procurement of Universal Modular Mast spare parts and cylinders, acting as a direct follow-on to Contract N64498-21-D-4022. This procurement is justified under FAR 6.302-1 due to the unique and proprietary technical expertise held by L3Harris Technologies, which enables the continued support of critical UMM systems on Virginia- and Columbia-class submarines without competition. The contract will span a 60-month ordering period following award, with delivery and performance occurring at the Philadelphia, Pennsylvania location, consistent with the contracting office’s physical presence and operational requirements. While no estimated contract value, pricing details, or specific line item numbers are provided in the presolicitation, the structure indicates a long-term framework for recurring demand with maximum quantities per part defined but not disclosed. The contractor is expected to supply non-commercial components with adherence to prior technical standards established under the predecessor contract, with acceptance performed by the government at the destination site. No explicit packaging, marking, inspection, or quality standards are detailed in the available documentation, though compliance with established defense procurement norms for sensitive submarine systems is implied; inspection responsibilities fall to the government, and delivery logistics are expected to align with common Department of Defense practices such as WAWF invoicing. Security clearances are implicitly required for personnel working on classified submarine platforms, and the contractor’s proprietary knowledge of UMM systems underpins the sole-source rationale, with no open competition anticipated. Administrative details including contracting officer representative, payment office, or accounting data are not provided, and the presolicitation excludes specific contract clauses, representations, certifications, evaluation factors, or attachment lists. All formal requirements will be defined in the subsequent solicitation, with submissions due by July 8, 2026, through the designated office in Philadelphia, PA. The procurement maintains continuity of capability, ensuring uninterrupted maintenance and operational readiness for the Navy’s strategic submarine fleet.
