The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure circuit card assemblies and similar replacement parts for repair and modification purposes. The procurement involves a quantity of four units of National Stock Number (NSN) 7H-5998-015190914, with delivery terms set as FOB Origin. These components are critical for maintaining operational readiness and are not available for competitive procurement due to the government's determination that it is uneconomical to acquire the necessary data or rights for alternative sourcing. Interested parties should contact Julie Smith at (717) 605-5805 or via email at JULIE.SMITH2@NAVY.MIL for further details, with proposals due within 45 days of the notice publication.
