# SAM #WA2026 F-22 Next-Generation Hydrogenated Dielectric Coolant Fluid Market Research **Buyer:** AFLCMC F-22 Division **Posted:** October 19, 2026 **Respond By:** November 03, 2026 **Identifier:** WA2026 **NAICS:** 336411, 325998 The Air Force is researching synthetic hydrocarbon dielectric coolant options to improve heat transfer in the F-22. - **Government buyer:** Department of the Air Force; Air Force Life Cycle Management Center (AFLCMC), Fighters & Advanced Aircraft Directorate, F-22 Division, Modernization Branch (AFLCMC/WAR), Wright-Patterson Air Force Base. - **Request:** Market information on next-generation hydrogenated dielectric coolant fluid for the F-22. The desired fluid should use a synthetic hydrocarbon base oil, with suitable additives as needed. - **Performance goals:** Improve one or more heat-transfer-related properties, including density, thermal conductivity, specific heat, and coefficient of thermal expansion. The RFI provides current-coolant benchmarks for comparison. - **Products and quantities:** One coolant-fluid category is described; no part number or quantity is specified. - **OEMs and vendors:** No product manufacturers, OEMs, or vendors are named in the materials. - **Opportunity context:** This is market research, not a solicitation or commitment to purchase. ### Description

The Modernization Branch of the F-22 Division (AFLCMC/WAR) is exploring the market for qualified firms to provide next-generation hydrogenated, dielectric cooling fluid. The material shall consist of a synthetic, hydrocarbon base oil with suitable additives as needed. This Sources Sought/RFI is looking for information on improved heat transfer capability. While calculating exact forced convection heat transfer requires parameters outside of fluid properties (e.g. velocity, pipe diameter, etc.), the F-22 Division seeks to improve one or more fluid properties that correlate to improved heat transfer capability. Current coolant density, thermal conductivity, specific heat values, and coefficient of thermal expansion are listed within the attachment to this RFI.
