This is a firm-fixed-price purchase order for $632,336.75 awarded by the Naval Supply Systems Command (NAVSUP) to Dewey Electronics Corporation, a small business manufacturer of military electronics and power systems. The contract is for the procurement of eight underwater sea valves under NSN 7H-6605-005408683, with an ultimate completion date of May 5, 2025. The original solicitation was a total small business set-aside, as the government determined it was uneconomical to obtain the technical data needed to facilitate competition. Dewey Electronics is a prime contractor for NAVSUP and holds multiple indefinite delivery contracts (IDCs) across the Defense Logistics Agency and Army Communications-Electronics Command, enabling streamlined ordering of specialized parts to support military systems sustainment.
