NASA’s X-59 quiet supersonic aircraft completed its first cross-country journey from Edwards Air Force Base in California to Kennedy Space Center in Florida, with stops in El Paso, Fort Worth and Birmingham along the way.
The milestone follows the X-59’s maiden flight, which occurred on an October 28, 2025 date, marking the first flight anniversary.
During the cross-country trip, the aircraft reportedly achieved a maximum speed of Mach 1.53 (about 1,010 mph or 1,625 km/h) and an altitude exceeding 56,000 feet, according to the reported highlights.
NASA notes that the X-59 has conducted more than 40 additional test flights, gradually expanding its flight-test envelope as part of its extensive testing program.
Developed by Lockheed Martin’s Skunk Works for NASA’s Quesst mission, the aircraft is designed to replace the traditional sonic boom with a quieter sonic thump, a hallmark of its revolutionary quiet supersonic technology.
NASA is moving toward acoustic validation to measure the aircraft’s actual noise signature during supersonic flight, as the program gathers data and public feedback that could influence future regulations on overland supersonic flight.
