The U.S. Government is conducting market research to identify potential sources with the expertise, capabilities, and experience needed for qualification and production of X-Band Receive Microwave Assemblies. The security clearance level and foreign participation have not been determined, but the contractor should anticipate working with military, civilian, national partner, and contract personnel from various services and agencies. This Sources Sought is for informational purposes only and is not an RFP, RFQ, or IFB, and it does not constitute a commitment by the Government. Interested parties may review documents containing the RMA requirements, technical data package, and Contractor Capability Survey, with both large and small businesses encouraged to participate, including through teaming, joint ventures, or subcontracting arrangements. Small business respondents should note that no set-aside decision has been made, may identify work areas they believe should be broken out exclusively for Small Businesses, and should submit questions in writing to the listed contracting and technical contacts.
