Engine Government Reference Architecture (eGRA) RFI
The U.S. Air Force is seeking industry feedback on its Engine Government Reference Architecture (eGRA) Release 2, a model-based tool for standardizing propulsion system requirements and sustainment. This is a Request for Information (RFI) only, not a solicitation for proposals, and the government will not pay for response costs. Interested parties can access the eGRA and Digital Engineering Style Guide, but must have active USAF contracts and systems for handling Controlled Unclassified Information. Responses, including a white paper or in-person presentation, are due by August 24, 2026, with an eGRA workshop and one-on-one engagements scheduled at the Turbine Engine Technology Symposium (TETS) 2026. No budget or performance location is specified.
