The Department of Defense, specifically the Department of the Navy, is seeking to procure the repair and modification of circuit card assemblies, with a focus on five units identified by NSN 7H-5998-015288373-GL. The procurement is intended to be a sole-source contract with Lockheed Martin Corp, as the government does not own the necessary data or rights to purchase or contract the repair from other sources, making it uneconomical to reverse engineer the part. This circuit card assembly is critical for various defense applications, and the contract is expected to be awarded under a Basic Ordering Agreement (BOA) with a firm-fixed price or not-to-exceed structure. Interested parties may submit their interest and capability statements to the primary contact, Leo Dougherty, at LEO.T.DOUGHERTY3.CIV@US.NAVY.MIL, within 45 days of the notice publication.
