NASA's Armstrong Flight Research Center is seeking information from potential sources for the production of Jet Propellant Thermally Stable (JPTS) jet fuel to support its ER-2 Airborne Science Program aircraft. The fuel must comply with the draft Military Detail Specification (MIL-DTL)-25524H(USAF) dated October 8, 2025, which outlines the chemical and physical requirements, including necessary additives and testing methods for qualification and conformance inspections. This procurement is crucial for ensuring the operational readiness of military weapon systems that utilize JPTS fuel, with an estimated annual production of 125,000 gallons over a ten-year period. Interested firms are encouraged to submit capability statements, including anticipated subcontracting goals for various socioeconomic categories, by January 5, 2025, to Jenni Schnarr at jennifer.schnarr@nasa.gov, referencing notice number 80AFRC26SS0001.
