The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure the repair and modification of circuit card assemblies. The requirement involves the repair of 12 units of circuit card assembly, identified by part number 63E917089G14, with a delivery term of FOB Origin. These assemblies are critical components in various defense systems, and the government has determined that it is uneconomical to acquire the data or rights necessary to source these repairs from alternative suppliers. Interested parties should direct inquiries to Leo Dougherty at (717) 605-4614 or via email at LEO.T.DOUGHERTY3.CIV@US.NAVY.MIL, with proposals due within 45 days of the notice publication. The government intends to award a sole-source contract to Lockheed Martin Corp under Basic Ordering Agreement N0010422GZW01.
