X-59 Soars: A New Era in Supersonic Flight Begins

PALMDALE, Calif., Oct. 28, 2025 /PRNewswire/ -- Lockheed Martin Skunk Works^® (NYSE: LMT), in partnership with NASA, successfully completed the first flight of the X-59, a revolutionary, quiet supersonic aircraft designed to pave the way for faster commercial air travel. 

The X-59 took off from Skunk Works' facility at U.S. Air Force Plant 42 in Palmdale, California, before landing near NASA's Armstrong Flight Research Center in Edwards, California. The X-59 performed exactly as planned, verifying initial flying qualities and air data performance on the way to a safe landing at its new home.

"We are thrilled to achieve the first flight of the X-59," said OJ Sanchez, vice president and general manager of Lockheed Martin Skunk Works. "This aircraft is a testament to the innovation and expertise of our joint team, and we are proud to be at the forefront of quiet supersonic technology development." 

The X-59 is a one-of-a-kind supersonic aircraft designed to demonstrate the ability to fly at supersonic speeds while reducing the sonic boom to a gentle thump. In doing so, the X-59 aims to overcome one of the primary barriers to supersonic commercial flight, which is currently restricted over land due to noise concerns. The X-59's successful development and flight testing will inform the establishment of new data-driven acceptable noise thresholds related to supersonic commercial flight over land, paving the way for a new generation of supersonic aircraft that can efficiently and sustainably transport passengers and cargo twice as fast as aircraft today. 

"X-59 is a symbol of American ingenuity. The American spirit knows no bounds. It's part of our DNA – the desire to go farther, faster, and even quieter than anyone has ever gone before. This work sustains America's place as the leader in aviation and has the potential to change the way the public flies," said Sean Duffy, acting NASA Administrator. 

Skunk Works will continue to lead the aircraft's initial flight test campaign, working closely with NASA to expand the X-59's flight envelope over the coming months. Part of this test journey will include the X-59's first supersonic flights, where the aircraft will achieve the optimal speed and altitude for a quiet boom. This will enable NASA to operate the X-59 to measure its sound signature and conduct community acceptance testing. 

This achievement demonstrates Lockheed Martin's commitment to pushing the boundaries of aerospace innovation and its dedication to creating cutting-edge solutions for the future of flight.
