This is a market research notice to identify potential manufacturers for an Input Output Concentrator part for the KC-135 aircraft, not a solicitation for bids. The work involves manufacturing, testing, and supply chain management, with performance linked to having a current license or agreement with the Original Equipment Manufacturer. Interested companies must have manufactured the item or a similar one within the past 36 months and should submit details of their OEM license or agreement, company information, and small business status. Responses are for planning purposes only, and no funds are available for the information requested. The government is interested in all business types, including various small business classifications.
