## What this funds

will provide U.S. industry with the technologies needed to maintain economic competitiveness, enhance energy security, and ensure continued American leadership in aviation. This budget restores NASA's role as the nation's engine for aeronautics innovation. It enables the agency to resume groundbreaking research and development, build and fly new X-planes, and deliver the transformative technologies that will define the next century of flight. By investing in NASA Aeronautics, the nation recommits to the NACA legacy of discovery and ensures that American aerospace remains unmatched--higher, farther, and faster than ever before. The NASA Aeronautics budget includes a planned decrease to the Low Boom Flight Demonstrator project as the project moves into flight. The budget request supports five programs within the agency's aeronautics portfolio: Airspace Operations and Safety Program (AOSP) - advances mobility through modernizing and transforming the national air traffic management system, in partnership with the FAA and the aviation community. The program conceives, develops, and demonstrates technologies to safely improve air traffic management systems for use in the National Airspace System (NAS). The program develops advanced technologies for a service oriented and federated NAS architecture to enable seamless integration of small, AAM vehicles with present-day aircraft to assure continued U.S. global leadership and industrial competitiveness. AOSP also works with other ARMD programs to define safe NAS operational requirements for the next generation of vehicles, mature new transformative concepts, and demonstrate integrated systems. In FY 2027, AOSP, in collaboration with FAA and industry, will: ' Evaluate capabilities, performance requirements, and safety assurance methods needed for safe automated taxi operations to reduce human workload in airfield operations; and ' Complete flight evaluation of a portable airspace management system with beyond visual line-of-sight and nighttime operations to enhance wildland fire aerial responses. Advanced Air Vehicles Program (AAVP) - develops tools, technologies, and concepts to enable safe new aircraft that are faster, quieter, and more fuel efficient. The program pioneers fundamental aeronautics research and matures the most promising concepts for transition to the community. AAVP works closely with the DoW to advance dual-use technologies for both civilian and military applications. Key focus areas include enabling major leaps in the safety and performance of subsonic fixed and rotary wing aircraft; overcoming noise and other technology challenges to high-speed flight, including demonstration of quiet supersonic flight with the X-59 aircraft; and understanding and resolving critical challenges of hypersonic flight. In FY 2027, AAVP will: ' Advance hypersonic propulsion technologies through flight testing with other government agencies and through ground testing of advanced engine concepts;
