The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure circuit card assemblies for repair and modification purposes. The procurement involves a quantity of three circuit card assemblies, identified by NSN 7H-5998-014708739-VN, which are critical components in various defense applications. This opportunity is set aside for small businesses under the Total Small Business Set-Aside (FAR 19.5) and is intended to be negotiated with a single source due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive procurement. Interested parties should contact Leigh E. Catchings at (717) 605-2864 or via email at Leigh.Catchings@navy.mil for further details, with proposals due within 45 days of the notice publication.
