The Department of Defense, through the Naval Surface Warfare Center Dahlgren Division (NSWC Dahlgren), is seeking proposals for the procurement of Data Cables, specifically the D1 EOD Receiver Data Cables (Manufacturer's Part Number: CBL-DATA-2005) from Persistent Systems LLC. This requirement is critical as the cables are currently in use, and introducing alternatives would necessitate extensive redesign and testing, potentially delaying operations by over a year. The contract will be awarded on a sole source basis, with a firm fixed-price arrangement for 50 units, and proposals are due by December 23, 2025, with an anticipated award date of January 23, 2026. Interested parties should contact Karen Major at karen.l.major7.civ@us.navy.mil or call 540-742-8863 for further details.
