NASA’s new quiet supersonic jet has completed its first successful test flight, marking a historic step for future commercial aviation. The X-59 aircraft, developed in partnership with Lockheed Martin, aims to transform how people travel by air through advanced noise-reduction technology.
The experimental jet lifted off from Palmdale, California, at U.S. Air Force Plant 42, and flew alongside a NASA chase plane. After roughly an hour, it landed safely at NASA’s Armstrong Flight Research Center, confirming the success of its initial subsonic flight. Engineers described the launch as a major validation of the aircraft’s innovative design.
Unlike traditional supersonic planes, the X-59 reduces the sonic boom to a gentle “thump.” Its long, needle-shaped body diffuses shock waves that normally create loud noise when breaking the sound barrier. The unique shape, while aerodynamic, limits forward visibility, so pilots use cockpit monitors instead of a windshield view.
The quiet supersonic jet represents years of collaboration between NASA and Lockheed Martin’s Skunk Works division. Since 2018, NASA has invested more than $500 million to develop the technology. The 100-foot aircraft reached about 230 mph at 12,000 feet during its debut flight but is designed to cruise at Mach 1.4, roughly 925 mph.
NASA officials praised the achievement, calling it a milestone in sustainable aviation. Acting NASA Administrator Sean Duffy said the aircraft embodies the American spirit of innovation and determination to “go farther, faster, and quieter than ever before.” Lockheed’s leadership echoed that sentiment, emphasizing how the project pushes boundaries in both science and engineering. Data gathered from these tests will help regulators reconsider long-standing bans on supersonic flight over land.
If approved, the technology could lead to new passenger jets capable of cutting travel times between major cities by half. The quiet supersonic jet could reintroduce supersonic travel to commercial aviation—without the thunderous sound that once grounded it.
