The U.S. Navy intends to award a sole source repair contract to Lockheed Martin for a Receiver Transmitter, as no technical data or rights are available to support competition. The work will be performed under an existing Basic Ordering Agreement, and the government will not delay the requirement for new source approval. Interested parties must submit a Source Approval Request if not already approved, but the timeline for this process will not be accommodated. All proposals must be received within 35 days of this synopsis for consideration. No budget amount or performance location is specified.
