The Defense Logistics Agency-Aberdeen is seeking sources to manufacture three Circuit Card Assemblies (CCAs) supporting the AN/ARN-149 Automatic Direction Finder, with NSNs covering both older and newer production variants. The government does not possess the technical data package for these parts, so interested parties must demonstrate their capability through evidence of prior manufacturing contracts, test results, and data rights. This is a Sources Sought notice for planning and market research only, not a request for quote, and no contract will be awarded based on responses. The information gathered will help determine if a competitive procurement or small business set-aside is feasible. Responses must be submitted via email to the designated points of contact, with no phone inquiries accepted.
