NASA and Lockheed Martin successfully tested the X-59 supersonic jet’s systems in a subsonic flight on October 28, 2025, advancing quiet supersonic travel.
NASA and Lockheed Martin successfully completed the first test flight of the X-59 supersonic jet on October 28, 2025, over southern California.
The subsonic flight tested the aircraft’s structural integrity and systems, marking a key milestone in NASA’s effort to develop quiet supersonic technology.
The X-59 is designed to produce only a mild "thump" instead of a disruptive sonic boom, potentially enabling future commercial flights over land.
If noise levels meet expectations, the technology could revolutionize air travel by cutting flight times between major U.S. cities in half and paving the way for regulatory approval of supersonic travel.
