This is a Request for Information (RFI) and Sources Sought notice, not a solicitation, seeking market research on contractor capability. The Air Force Life Cycle Management Center seeks sources able to provide new, fully serviceable F100-229 augmentor modules in exchange for multiple F100-229 engines from the government, with no funding provided. The exchange is property-for-property only, and modules must be free of corrosion and physical damage. Interested parties are asked to submit company information and capabilities, with proprietary information clearly marked. This is an opportunity to express interest and provide feedback, but it does not constitute a commitment to contract.
