How to bid on the Engine Government Reference Architecture (eGRA) RFI from the Air Force
What the Air Force is buying and why it matters
The Department of the Air Force is seeking industry feedback on its Engine Government Reference Architecture (eGRA). This is a digital model designed to support the requirements, architecture, acquisition, and sustainment of propulsion systems. The Air Force wants to understand industry approaches to propulsion system architecting and how to evolve its existing tools to complement these approaches.
This is a Request for Information (RFI), not a Request for Proposal (RFP). It is for planning purposes only and does not guarantee a future contract. Your feedback will help the Air Force develop a tool that adds value to both government and industry users in propulsion acquisition efforts.
Key dates and what happens at the deadline
This RFI was published on July 24, 2026. The deadline for initial coordination and responses is August 24, 2026, at 5:00 PM Eastern Time. All unclassified responses should be submitted by this date.
If you choose to provide an in-person oral presentation, it will be a 30-minute session tentatively scheduled for Thursday, September 3, 2026, at the Turbine Engine Technology Symposium (TETS) 2026.
Who this opportunity suits
This opportunity is suitable for companies with expertise in propulsion system architecting and digital engineering. Specifically, firms with active contracts with the USAF and appropriate systems for storing and processing Controlled Unclassified Information (CUI) will be able to access the eGRA Release 2 and related materials.
The Air Force is looking for feedback on how industry would incorporate the eGRA into their modeling practices, how it complements or conflicts with current practices, and how a model-based approach could link requirements to system architecture elements. This RFI is for companies involved in equipment and systems engineering for propulsion.
How to respond
To respond, you must first request access to the eGRA Release 2, introductory materials, and the Digital Engineering Style Guide (DESG). Contact Major Andrew Cottle, Mr. Jed Cox, and Captain Dustin Herridge, and include your CAGE code. You will need an active USAF contract and systems capable of handling Controlled Unclassified Information (CUI) to receive these materials.
You can provide feedback in one or both of the following ways: a white paper not exceeding 10 pages, or a 30-minute in-person oral presentation at the Turbine Engine Technology Symposium (TETS) 2026. Initial responses or coordination must be completed by August 24, 2026, at 5:00 PM Eastern Time. Unclassified responses should be submitted via secure email or secure website to the technical POC and the contracting officer. Clearly mark any proprietary information.
Practical tips for preparing a competitive response
When preparing your response, focus on addressing the specific questions outlined in the RFI. Describe how your company would integrate the eGRA into your existing modeling practices and highlight aspects that are complementary or in conflict. Explain how you would leverage a model-based approach to link requirements to system architecture elements.
Consider discussing how the eGRA attributes could enhance your processes for validating design satisfaction of requirements. Also, describe potential approaches and challenges in incorporating your standard work into a government-accessible model throughout the program lifecycle. Finally, offer recommendations for the continued development of the eGRA to ensure its usefulness in propulsion system acquisition and sustainment.
