SPECIAL NOTICE – CALL FOR PROPOSALS Department of the Air Force / Air Force Materiel Command (AFMC) Air Force Research Laboratory (AFRL) Rocket Propulsion Division – Edwards AFB, CA HERMES Broad Agency Announcement (BAA) FA9300-20-S-0001 CALL: Rotating Detonation Rocket Engine-Combined Cycle (RDRE-CC) Flight Demonstration Parent Solicitation Number: FA9300-20-S-0001 Call Identifier: FA9300-20-S-0001-CALL-RDRE-CC Prior Market Research Notice: RFIFA930026R0001 NAICS Code: 541715 – Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology) Product Service Code (PSC): AC11 – National Defense R&D Services; Department of Defense; Basic Research Response Date (Step 1 - White Papers): [16 NOV 2026] at 1600 PST Set-Aside: Full and Open Competition (under RFO 35.102) 1. Program Description The Air Force Research Laboratory, Rocket Propulsion Division (AFRL/RJP), located at Edwards AFB, CA, is issuing a formal Two-Step Call for Proposals under the overarching HERMES Broad Agency Announcement (BAA) FA9300-20-S-0001. This Call follows the market research previously conducted and publicized under RFI Notice ID RFIFA930026R0001. AFRL/RJP seeks innovative research and development approaches to mature advanced Rotating Detonation Rocket Engine-Combined Cycle (RDRE-CC) propulsion systems from Technology Readiness Level (TRL) 3 to TRL 6. This research effort is intended to culminate in a ground-launched, sounding-rocket-boosted flight demonstration to validate the system's operational viability for future High-Speed Affordable Mass Munitions (HAMM). The scope encompasses: Maturation and demonstration of RDRE-CC propulsion technology through RDRE development and test, integrated RDRE-CC direct-connect and freejet testing, vehicle development, and flight demonstration.The anticipated Period of Performance (PoP) for resultant award(s) is 36 to 48 months. 2. Acquisition Structure (Two-Step BAA Process) In accordance with RFO 35.102 and Section IV of the Hermes Master BAA, this Call utilizes a Two-Step solicitation process: Step 1: White Paper Submission Interested offerors are invited to submit a concise White Paper outlining their proposed technical architecture, compliance with the seven Specific Test Objectives (STOs), schedule milestones, and a Rough Order of Magnitude (ROM) cost. No contract awards will be made based solely upon Step 1 White Paper submissions. Step 2: Request for Proposals (RFP) The Government will evaluate White Papers using a Peer/Scientific Review process based on the criteria published in the Call. Only those offerors whose White Papers are evaluated as having high technical merit, relevance to HAMM objectives, and for which funding is available, will be formally invited to submit a full, high-fidelity Technical and Cost Proposal. The Government anticipates completing its Step 1 White Paper evaluations and issuing notifications within approximately six (6) to eight (8) weeks following the…
