Airlift Efficiency Commercial Solutions Opening (CSO)

The Air Force Operational Energy Office (SAF/IE) is issuing Commercial Solutions Opening FA4452‑25‑S‑C001 to obtain innovative, dual‑use propulsion concepts that improve airlift efficiency for both military and commercial transport aircraft, including blended‑wing‑body platforms. Offerors must submit an unclassified Solution Brief that describes a turbofan engine (35,000‑50,000 lb thrust, sea‑level static) incorporating new materials, designs, or manufacturing techniques to reduce cost, increase efficiency, and enhance performance. The brief must identify the technical approach, anticipated results, ancillary issues (certifications, algorithms, development methodologies), and a high‑level cost and schedule estimate, and must demonstrate that non‑federal sources will fund at least one‑third of the prototype effort. Solution briefs are evaluated equally on technical merit, importance to the agency, and price by scientific and subject‑matter experts; they will be classified as “Selectable” (advancing to Step Two) or “Not Selectable.” Selected offerors will be invited to submit a full Detailed Approach (Step Two), which must include: (1) Section A – company information, point‑of‑contact details, subcontractors, and an abstract; (2) Section B – a comprehensive technical solution, Statement of Work, deliverables, detailed project schedule, required government support, and a total price proposal with supporting cost data. Detailed Approaches are evaluated on the same three factors and categorized as Acceptable or Not Acceptable, with acceptance contingent on available funding. The solicitation is governed by FAR 52.212‑4/‑5 and may be awarded under an Other Transaction authority (10 U.S.C. 4022). All submissions remain valid for 180 days, and the AOI(s) remain open until 26 February 2026.
