The Department of Defense, specifically the Department of the Navy, is seeking to procure eight units of the Probe-Lead Assembly under a presolicitation notice. This procurement is for a specific National Stock Number (NSN 1H-6625-015390892-X3) and is intended for delivery to designated Defense Logistics Agency distribution centers in Pennsylvania and California. The goods are critical for electrical and electronic properties measuring and testing, and the government intends to negotiate with only one source due to the proprietary nature of the data required for the assembly. Interested parties must express their interest and capability within 45 days of the notice, and all inquiries should be directed to Haylea E. Winand at HAYLEA.E.WINAND.CIV@US.NAVY.MIL.
