The F/A-18 was used to test a transmitter for an air navigation system, called the Airborne Location Integrating Geospatial Navigation System, or ALIGNS. This system, designed to allow pilots to position their aircraft at precise distances to each other, will be critical for acoustic validation efforts of NASA's next supersonic X-plane, the X-59 Quiet SuperSonic Technology.

NASA’s Cross Flow Attenuated Natural Laminar Flow test article is mounted beneath the agency’s F-15 research aircraft ahead of the design’s high-speed taxi test on Tuesday, Jan. 12, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California. The 3-foot-tall scale model is designed to increase a phenomenon known as laminar flow and reduce drag, improving efficiency in large, swept wings like those found on most commercial aircraft.

NASA ground crew prepares the agency’s F-15 research aircraft and Cross Flow Attenuated Natural Laminar Flow (CATNLF) test article ahead of its first high-speed taxi test on Tuesday, Jan. 12, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California. The CATNLF design aims to reduce drag on wing surfaces to improve efficiency and, in turn, reduce fuel burn.

NASA’s Cross Flow Attenuated Natural Laminar Flow (CATNLF) scale model completes its first major milestone – high-speed taxi test – Tuesday, Jan. 12, 2026, at Edwards Air Force Base in California. NASA’s F-15 research aircraft, with the 3-foot-tall test article mounted on its underside, reached speeds of approximately 144 mph during testing. If successful, the technology could be applied to future commercial aircraft to improve efficiency and potentially reduce fuel consumption.

NASA’s Crossflow Attenuated Natural Laminar Flow (CATNLF) scale-model wing flies on a NASA F-15 research jet during a test flight from NASA’s Armstrong Flight Research Center in Edwards, California. The CATNLF technology is designed to maintain smooth airflow, known as laminar flow. NASA will continue flight tests to collect data that validates the CATNLF design and its potential to improve laminar flow, reducing drag and lowering fuel costs for future commercial aircraft.

NASA’s Crossflow Attenuated Natural Laminar Flow (CATNLF) scale-model wing flies for the first time on a NASA F-15 research jet during a test flight from NASA’s Armstrong Flight Research Center in Edwards, California. The 75-minute flight confirmed the aircraft could maneuver safely with the approximately 3-foot-tall test article mounted beneath it. NASA will continue flight tests to collect data that validates the CATNLF design and its potential to improve laminar flow, reducing drag and lowering fuel costs for future commercial aircraft.
