The National Aeronautics and Space Administration (NASA) Ames Research Center is seeking to procure aviation services for the Phasa-35 High-Altitude Long Endurance (HALE) platform, aimed at supporting airborne science missions from April 10, 2025, to September 29, 2030. The procurement includes engineering analyses, payload integration, aircraft modifications, testing, and flight operations support, all of which must comply with NASA standards and airworthiness requirements to facilitate critical scientific data collection. This opportunity is particularly significant as it involves a sole source contract with BAE Systems, the platform's developer and sole operator, due to their unique technical expertise and operational capabilities. Interested organizations are invited to submit their qualifications to Joshua Taggart via email by 5:00 p.m. CT on March 26, 2025, for consideration in determining the potential for competitive acquisition.
