The Defense Logistics Agency-Aberdeen, on behalf of the Army Integrated Logistics Supply Center, is seeking sources able to manufacture specific parts for the Common AN/APX Transponder, including a Circuit Card Assembly and a Crypto Card. The government does not possess specifications or detailed drawings, so interested parties must demonstrate their manufacturing capability by submitting documentation such as questionnaires, drawings, test results, and prior contract or data rights information. This is a sources sought announcement for market research and planning purposes only, not a request for quote or proposal, and no contract will be awarded based on it. Interested companies must respond via email to the listed technical and small business points of contact, including their company name, CAGE code, and a technical point of contact with contact information. No phone inquiries will be accepted.
