NASA’s X-59 supersonic jet has completed its first test flight on Tuesday morning, marking a major step toward reviving high-speed commercial air travel, only this time, without the thunderous sonic boom.
Developed in partnership with Lockheed Martin’s Skunk Works division, the X-59 was built to achieve supersonic speeds while dramatically reducing noise. During its debut flight, the single-engine jet flew from Palmdale to NASA’s Armstrong Flight Research Center in Edwards, reaching subsonic speeds of 230 mph (370 km/h) and a peak altitude of 12,000 feet. Lockheed Martin confirmed the aircraft “performed exactly as planned.”
Stretching just under 100 feet in length, the X-59’s long, sculpted nose and slender frame are designed to reshape shockwaves created at supersonic speeds. Instead of the disruptive sonic boom that has restricted commercial supersonic flight over land for decades, NASA says the X-59 will produce only a gentle “sonic thud”, roughly as loud as a washing machine.
The agency hopes this breakthrough could lead to new regulations allowing faster-than-sound travel over populated areas, potentially halving flight times between major global cities. Future tests will confirm the jet’s true noise signature once it hits its intended cruising speed of 925 mph (Mach 1.4) and altitude of 55,000 feet, more than twice the cruising height of standard passenger jets.
“This is part of our DNA, to go farther, faster, and quieter than anyone before,” said NASA’s acting administrator, Sean Duffy. “This mission could redefine the way the world flies.”
NASA’s X-59 joins a growing field of supersonic contenders, including Boom Supersonic and Spike Aerospace, who are all racing to succeed the iconic Concorde. The British-French airliner was retired in 2003 after three decades of service due to high operating costs and environmental challenges.
For now, NASA and Lockheed Martin will continue refining the X-59’s design and sound data, with more test flights planned in the coming months, including its first official supersonic run. The age of quiet speed may finally be upon us.
