The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support Mechanics, is seeking to procure five circuit card assemblies for repair and modification purposes. The procurement involves a specific National Stock Number (NSN 7H-5998-016153119-VN) and is limited to a single source due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive procurement. This circuit card assembly is critical for maintaining operational capabilities within the Navy's electronic systems. Interested parties are encouraged to express their interest and capability to fulfill this requirement within 45 days of the notice, with all inquiries directed to Christian D. Spangenberg at the provided contact information.
