How to bid on Solutions to Enhance US Rocket-Based Combined Cycle (RBCC) Propulsion Technologies from the DEPT of the Air Force
What the Air Force is buying and why it matters
The Department of the Air Force is seeking information on technologies to improve Rocket-Based Combined Cycle (RBCC) propulsion for high-speed aircraft. They are particularly interested in Rotating Detonation Rocket Engines (RDRE) that use storable, non-cryogenic fuels like High Test Peroxide (HTP) or other liquid non-cryogenic oxidizers in combination with Rocket Propellant (RP) or Jet Fuel.
The goal is to identify current technologies, US industry capabilities, and government resources that can be leveraged, as well as areas needing further investment. The Air Force wants solutions that minimize weight, maximize scalability and mission utility, optimize propulsion-airframe integration, and minimize logistics. This RFI is for market research only and does not guarantee a future solicitation or contract award.
Key dates and what happens at the deadline
This Request for Information (RFI) was published on July 14, 2026. All responses must be submitted by August 10, 2026, at 1:00 PM ET. This is a firm deadline, and late submissions will not be considered.
The Air Force is not seeking proposals or white papers at this time, and this RFI does not commit the government to issue a future Request for Proposal (RFP) or award a contract. The government will not pay for any costs incurred in responding to this RFI. Responses will not be returned, and respondents will not be notified of the review results.
Who this opportunity suits
This opportunity is suitable for professional firms with expertise in advanced propulsion systems, particularly those with experience in Rocket-Based Combined Cycle (RBCC) technologies and Rotating Detonation Rocket Engines (RDRE). Companies specializing in aerospace engineering, materials science for high-temperature applications, and fuel systems for storable, non-cryogenic propellants would find this relevant.
The Air Force is looking for solutions that address specific aspects such as minimizing weight, maximizing scalability and mission utility, optimizing propulsion-airframe integration, and minimizing logistics. Firms that can demonstrate capabilities in these areas, especially with RDREs using HTP or similar liquid non-cryogenic oxidizers with RP or Jet Fuel, are encouraged to respond.
How to respond to this RFI
To respond, you need to submit your information electronically to the Contracting Officer. The primary contact is Alessandra Barzaghi-Martin at [email protected], and the secondary contact is Mathew Pierson at [email protected].
Your written response should be a maximum of five pages for each responsive scenario, using Microsoft Word and 11-point font, with a total response not exceeding 10 pages. Administrative information is not included in the page count. Include your company name, business size for the subject NAICS, Cage Code/SAM UEI, organization name, address, and the name and email of your designated point of contact. Submit your qualifications and any other pertinent information by the deadline.
Tips for preparing a competitive response
Focus your response on the specific technical areas outlined in the RFI, particularly regarding Rotating Detonation Rocket Engines (RDRE) and storable, non-cryogenic propellants. Clearly articulate how your proposed solutions address the Air Force's interest in minimizing weight, maximizing scalability, enhancing mission utility, improving propulsion-airframe integration, and minimizing logistics.
Even though this is an RFI, ensure your submission is well-organized and professional. Adhere strictly to the page limits and formatting requirements. Highlight your company's unique capabilities and any relevant past experience or research that aligns with the Air Force's stated goals. While proprietary information will be safeguarded, ensure it is clearly marked.
