About this opportunity
The Department of the Navy Naval Sea Systems Command, through Naval Surface Warfare Center (NSWC) Crane Division, is conducting market research to identify sources capable of providing Isolation Rings, critical components used in the TR-343 Transducer system that supports the AN/SQQ-89(V) Anti-Submarine Warfare combat system. These isolation rings provide essential electrical isolation for piezoelectric devices within the transducer assembly. The Government is issuing this Sources Sought announcement under DFARS procedures to assess the availability and technical capabilities of potential suppliers. Interested parties must demonstrate their capability to supply isolation rings and should provide information regarding performance on similar Government contracts. The due date for responses is January 9, 2026, and all interested parties must be properly registered in the System for Award Management (SAM) to participate in subsequent procurement activities.
This is a non-set-aside procurement; however, the Government actively encourages participation from small businesses, disadvantaged small businesses, HUBZone small businesses, woman-owned small businesses, veteran-owned small businesses, and historically black colleges and universities. The notice does not specify an incumbent contractor or provide an award value or budget range, as this is a pre-solicitation market research phase intended to gather information before formal solicitation. The correct Product and Service Code (PSC) for this procurement is 5845 (Underwater Sound Equipment), and the updated NAICS code is 325211 (Plastics Material and Resin Manufacturing), as corrected in Amendment 01. No specific quantity requirements, contract timeline, or performance metrics are detailed in this sources sought notice, as the primary objective is to establish a vendor base for future formal solicitation.
