The U.S. Navy intends to award a sole-source, one-year repair contract to Lockheed Martin for a digital-to-digital converter (NIIN 014139136), as they are the original equipment manufacturer and the only known source with the necessary data. No drawings or technical data are available for other suppliers. Interested firms not already approved must submit a Source Approval Request, but the procurement will not be delayed for approval. Responses to this notice must be submitted within 15 days to express interest in providing a commercial item, and all proposals received within 45 days will be considered. The location for performance is not specified, and no budget amount is provided.
