The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure circuit card assemblies under a presolicitation notice. The requirement includes the acquisition of three units of NSN 7H-5998-015064159, with delivery terms set to FOB Origin, and the procurement is restricted to specified sources due to the lack of available technical data for alternative suppliers. These circuit card assemblies are critical components in various defense systems, and the government intends to negotiate with only one source under FAR 6.302-1, although all responsible parties may express their interest and capabilities within 45 days of the notice. Interested vendors should contact Aaron McFee at (717) 605-2706 or via email at AARON.MCFEE@NAVY.MIL for further details.
